Questions related to Recycling
There is a debate of what's going to happen to those "obsolete" solar panels that will be discharged in the next ten years.
My first observation is: we know that there is a great potential in second hand panels because most of them can still produce electricity. This is more evident in third world countries where there is enough space to compensate for that loss in efficiency.
Second observation: even if the panels efficiency is 10% is still tempered glass with a frame which can be used for shading of open areas and could replace at a quarter of the price other materials such us policarbonate, acrilic or even thick non tempered glass !
Imagine you could cover your roof or porch with this "useless" solar panels and have a great picnic area, have playground for your children or even a green house where you can grow your veggies.
For me, the possibilities are end less.
What am I not seeing here? Is it possible that the logistics prices will out run the economic benefits? How about the environmental and social benefits?

I need to know the complete calculation how much mol percentage of palladium is left after recycling my catalyst do that I can understand how much metal has leached from the prepared catslyst
We are looking for a suitable sorbent to remove phosphorus (relatively low concentration of ca. 1 mg/L PO4-P) from lightly brackish water with around 6 PSU (Practical Salinity Unit, ca. 10 mS/cm), which can subsequently be reused as soil conditioner / fertilizer. So far we considering sorbents such as coated/modified biochar, calcareous materials or even recycled material such as crushed concrete according to various literature. However, we were wondering whether there is a sorbent which is specifically suitable for such a lightly brackish water.
I´m interested in the water usage of C&D recycling plants in relation to the capacity (water [m³]/waste [t].), following a "dry" treatment process to produce recycled aggregates. I´m assuming most water is used for cooling/irrigation for dust reduction. Thank you for any hints towards helpful information.
Hi everyone, i'm a student and a user of Simapro. In my actual study i need to modify an existing process on simapro. The particular process i have in input is chromium steel 18/8, but i need to define that the 70% of the composition of that material comes form recycled steel. Can someone help me please?

The demand for metals in the coming decades is expected to be booming due to the revolution occurring in the car industry and energy supply toward greener options. This phenomenon has led to a dilemma of how we should supply the metal required for this transition and achieve zero carbon emission targets. So my question is should we focus on mining new primary sources or pay attention to retrieving metals from generated solid wastes? What can be the proportion of each strategy in supplying metals? What's your opinion?
I am preparing polymeric blends from recyclable materials. What are the characterization techniques that should be used and how to prepare the samples (IR, DRX, SEM, TEM, etc)? Could you suggest technical sources and papers/books?
--- For all the Cities / Towns along the Rivers in India, the task of establishing the Sewerage Network alongwith Sewage Treatment Plant might not be a feasible option immediately at this point of time. So if all the Waste Outfalls / Drainage Channels leading to the River can be initiated as a points of Bioremediation ( onsite treatment option ), then it may eventually provide the scope for its' reuse or recycle for different meaningful purposes. Finally, as a whole the the pollutants loads to the Rivers might get reduced / minimised.
I need to find a proper method to prepare sample solution by digestion for Pt-Pd-Rh elements from spent automotive catalysts. Any suggestion except application of microwave-assisted digestion would help me.
Hello! I have a problem with a reformer kinetic implemented in Aspen Plus. I have a PFR reactor that need to be closed with a recycle. In this recycle there is a very small amount of H2 that invalidate the kinetic and gives me error, this is because in the reaction rate expression, some terms are divided for the partial pressure of H2, and therefor being so small, is like dive everything for zero and that is causing problem in the converge.
Is anyone of you familiar with such problem? There is a way to "eliminate" a component from a stream is present below a certain amount?
I’m currently searching statistical data about the use of plastic in food packaging and the waste derived from it, but I don’t find first hand updated information about it. Could you recommend me any publication, website or institution where I can obtain information?
Thank you for your attention
We know that, thermosetting plastic is a kind of unrecyclable material. It's melting point is estimated to be around 6000 degree C but starts to degrade at a temperature above 250-350 degree C. On other side of story a huge industry is already there remolding/recycling the thermo plastics. In such senerio taking thermosets as a sand and thermoplastic as cement, can we make a mixture of thermosets and thermo plastics with more durability like a concrete formed by mixture of sand and cement? What might be the challenges on this process? Is this way feasible? Is there any other better idea for recycle of thermosetting plastic?
I am 1st year 1st semester student of civil engineering. Hope to get your respond......!
I am working in the waste tires recycling area so, I am wondering if the problem of sand moving as a result of wind (which causes various obstructions for drivers) can be reduced by using waste tire rubber or other material. I would like to know is that possible? Is there anyone who has any idea about that?
1. You use Material 1 in Biology and after using it, you recycle it in Chemistry to come up with Material 2.
2. You use Material 1 in Biology and then its product is used in Chemistry, Physics, Earth Science.
3. Or any related activities that make use of similar or related ideas.
If you can share also your related studies, I highly appreciate it. Thanks!
Good morning, I am trying to understand whether pharmaceutical glass (Type I, II, and III) can be recycled in the US. Specifically my questions are as follows:
Glass (Type I, II, and III glass (used in pharmaceutical vials etc).
- Can these be recycled?
- If the caps are plastic, should they be separated or kept on?
- If the glass is coated on the outside with PE or PVC, can it still be recycled?
- Are there any limitations on recycling the container if it held a hazardous material?
Any guidance or related links/documents would be helpful!
Using electricity, a new method offers the possibility of recycling CO2 while also performing a notoriously difficult reaction, producing compounds potentially useful for drug development.
Scientists at the Institute for Chemical Reaction Design and Discovery (ICReDD) in Hokkaido University have developed a method that has the potential to help recycle waste CO2 while also producing molecules useful for drug development.
They demonstrate that a wide variety of substrates that exhibit highly negative reduction potentials can very efficiently undergo this unprecedented dearomative addition of two CO2 molecules.
Diverse organic resources like crop residues, dairy generated manures and byproducts from agro-industries are available for recycling in agriculture. It is known that these organic sources provide plant nutrients, improve soil properties and help mitigate climate change. So efficient organic recycling with the diverse organic resources is very important from agricultural production and climate change mitigation point of view. But to get real benefits from this, how to upscale the recycling at farm, village, regional and country level?
I tested my compressive strength samples at 3, 7, 28, 56,91, 182, and 360 days for standard concrete and recycled aggregates concrete. Up to 56 days, standard concrete samples behave better than recycled, but at later ages, especially 182 and 360 days, recycled aggregate concrete is better in strength increment.
As we all know that the rate of using display technologies has been soaring up with each passing day. The need for glass materials for display devices such as smartphones, touch screens, or the like emerges as indispensable. In this sense, what are their rate of recycling and/or reusing for fostering the circular economy model, as well as towards carbon neutrality aims? Can anyone help to realize the facts in terms of statistical data?
Many thanks in advance for your kind contributions.
Catalytic depolymerization of polyoleﬁns is a promising chemical recycling strategy to create value-added products from waste plastics, which are accumulating in landﬁlls and the natural environment at unsustainable rates. Consequently, what is the cheapest way for the chemical recycling of polypropylene (PP) and what will be the product or products? All posts are welcome. Thanks for your kind interaction.
How many times actually we can recycle the solar panels? Is the recycled one cost less? Does using the recycled one affect its energy absorption efficiency?
I want to isolate Plasma membrane, ER from cultured cancer cells for lipidomics. Would like to discuss the protocol for the same and your experience, any suggestions welcome!
What are the possible polymers that can sustitute commercial polypropylene? Such substitutes should be "chemically recyclable", that is, depolymerizable into monomers and the monomers are repolymerizable. Examples and relevant publications are needed!
I am looking for articles or case studies that quantify how long and by what method an education and outreach campaign persists long-term. I am looking for environmental campaigns but would take input from the health sector too. For example, if a recycling program provides multiple targeted education and outreach "touches" to get households to recycle a particular commodity or keep a particular contaminate out, how long would one expect that the change would last before needing to go back into the community and message again as a reminder? Any research with not only short-term evaluation results but an analysis showing "long-term" change using targeted outreach for an environmental action would be welcome.
During the DC casting process of aluminum alloys, the use of bone ash, which contains Ca, is widely used and in many cases overly used and thus creates the potential for significant Ca contamination when recycling the scrap over and over. What effect will this have to the oxide generation on the surface of the as-cast product?
In this project we need to compare the environmental impact of two valorization routes for a shielding antistatic bag: incineration with energy recovery and chemical “destructuration” in formic acid followed by mechanical recycling of the different layers.
We already identified that the anti-static bag was made of 2 layers (one of PE, one of PET (there is an aluminium layer that is out of our scope in that case)).
Once we have our flow sheets for the two valorization routes, does someone can help us with the quantification of our inputs/outputs? Are we supposed to check on SimaPro or with some scientific literature?
Then, we'll be able to compare the environmental impacts of the new valorization/recycling processes with the incineration process based on a life cycle assessment (LCA) analysis
Thank you :)
In general dentistry metal waste materials are discarded as biomedical waste and handled with other biomedical waste materials,is there any special way of discarding or recycling the metals?
What are the examples of eco-innovations that can significantly reduce the scale of environmental pollution and reduce greenhouse gas emissions and slow down the faster global warming process?
Currently, the problem of growing garbage with unsorted waste is ignored in many countries, but because in the future the negative aspects of the problem of environmental pollution, including plastic, will grow, so in the future other countries will also try to solve this problem.
The problem of environmental pollution with plastic waste is one of the key global problems. This problem should be solved in all countries, and above all those that "generate" the most. The European Union has already undertaken specific measures in this direction, eg by introducing legal regulations under which plastic will be withdrawn from packaging by 2021 and replaced with biodegradable materials such as vegetable origin. However, these regulations concern only European Union countries.
Similarly with other aspects of environmental pollution and greenhouse gas emissions. Also, some large global economies are currently ignoring growing problems. But such an approach must be quickly changed, because there is little time to implement pro-ecological reforms, primarily in terms of reducing environmental pollution and reducing greenhouse gas emissions.
As regards the reduction of greenhouse gas emissions, it is necessary to reform the energy sector in such a way as to switch from the production of electricity based on the classic energy based on the combustion of minerals to technologies based on the development of renewable energy sources. In addition, it is also important to develop electromobility in the automotive industry and other types of transport.
The global warming process is progressing faster, the scale of the negative effects of climatic disasters and weather anomalies, which are a consequence of the ever-faster global warming process, is increasing. There is little time left, according to climatologists only max. over a dozen years to implement the necessary ecological reforms and innovations, including in the area of energy development based on renewable energy sources, to stop or even significantly slow down the ever-faster global warming process.
In addition, one of the main types of eco-innovations includes innovative technologies for building zero-energy houses and residential buildings. The special design and materials used ensure low energy consumption and closure of the energy cycle in a cycle in which household power plants generating heat and electricity based on renewable energy sources are an integral part, primarily through the use of photovoltaic panels and wind farms.
As part of the implementation of the necessary pro-ecological reforms, it is also necessary to develop eco-innovations that will improve the automation of waste segregation and recycling processes. In addition, it is also important to create innovative technologies for the creation of new biodegradable materials that will replace plastic in packaging.
A good solution is the use of packaging made of biodegradable materials of origin, eg vegetable, on the basis of raw materials in the form of crops. These types of packaging could be consumed after their use, such as plates and cutlery made of rice or other cereals, or could be processed into compost for animal feed or for fertilizing arable land, or for incineration in a specially built incineration plant.
In connection with the above, the increasingly common application of ecological innovations, which are necessary to reduce greenhouse gas emissions and to limit, slow down the faster global warming process, will also contribute to increasing the scale of sustainable green economic development realized according to the green economy concept.
These processes of implementation of ecological innovations and implementation of pro-ecological reforms should be conducted in all countries, and to the largest extent in developed and developing countries, industrialized countries, including the largest economies in the world, which are the largest emitters of greenhouse gases and producers of garbage and non-degradable waste, toxic or hardly degradable.
Do you agree with me on the above matter?
In the context of the above issues, I am asking you the following question:
What are the examples of eco-innovations that can significantly reduce the scale of environmental pollution and reduce greenhouse gas emissions and slow down the faster global warming process?
I invite you to the discussion
Thank you very much
In spite of constantly improved waste segregation systems and recycling, the problem of growing garbage dumps on which waste is not biodegradable and polluting is still growing.
In view of the above, will replacing all plastic packaging with their biodegradable substitutes solve the problem of rubbish?
The CO2 used in supercritical extractions can be recycled?
If yes, for how long can we use the same CO2?
If no, do we despose the same amount used in the beginning? Does it have the same chemical and physical structure?
With the increasing demand, the consumption of metallic materials is increasing. But the primary sources of these materials (ores) are limited. So, there is an urgent need for an efficient recycling technique to meet the increasing demand. There are mainly two techniques, powder metallurgy and casting, used for recycling metallic materials. Which is the better technique, powder metallurgy or casting?
I am urgently looking for information on the amount [t] of waste from used photovoltaic panels and lithium batteries at the level of Poland, the EU and the world from 2019 with projections until 2050.
I would need to prepare a review on wastewater treatment and recycling solutions for treatment of water from wash downs of aircraft and parts. Since it is not my typical area of expertise I would appreciate if you can help me with some links or your experiences. Do you know some airports and way they treat wastewater from planes and parts washing? Thanks a lot.

Life Cycle Analysis is considering ideal situations of recycling, etc. For example when using EcoInvent database in simaPro, I can't see how to get real-life scenarios of landfills. Anyone who had already worked on LCA of real-life landfills / discharge in Developing Countries ?
I have residue of solid silica and I want amorphous nano-silica in 4-6 hours? Which technique or process will be more efficient to bring down the size of silica below 100nm in 4-6 hours?
There seems to be interest in circular economy thinking of the type production-consumption-externality such as produce-use-recycle or firm-consumer-pollution cost, which means this thinking is still business as usual thinking, but with a plus.
The Brundtland commission (1987) wanted us to go beyond business as usual to properly address the environmental crisis, which Rio plus 20 conference (UNCSD 2012) took to be to shift to green economy thinking, which would lead us to think that by this time end of 2019 those heavily involved in RIO + 20 2012 should have by now a sound and accepted idea of circular green market economy thinking....But that seems not to be the case.. .and curiosity in my mind is why not?
It looks to me that academic attention since 2012 has been misplaced and given to a non-green circular process, which raises the question posted above: Circular economy thinking vrs circular green economy thinking, which type of thinking should be now the priority, if not the rule in the face of the environmental crisis?
What do you think? I am interested in the views/ideas of the participants not on views/ideas of third parties.
Wish an excellent new year to all!

Dear All Researchers and Engineers,
We are organizing an International Symposium on Construction Resources for Environmentally Sustainable Technologies (CREST) during 10-12 March, 2020. On behalf of the chairman Prof. Hemanta Hazarika, we would like to invite all those interested in participating in the event. Please send your abstracts and papers, which will be published by Springer.
In india many rural people are creating jugad using some garbage and recyclable waste saving so much of natural and man made resources।The people making such rural tecno products must be rewarded as they help us to save lots of energy fuel human labour and natural resources।
In my opinion, such factors as effective waste segregation, recycling, reduction of plastic packaging, development of renewable energy sources, electromobility in motorization, afforestation, architectural ecological innovations, etc. are one of the most important factors to enable real implementation of sustainable pro-ecological development based on a new, green economy.
In view of the above, I would like to ask you: What are the key determinants of the implementation of sustainable pro-ecological development according to the concept of green economy?
Please, answer, comments. I invite you to the discussion
I need help in knowing the economic feasibility of waste recycling projects, especially in developing countries where unemployment rates are high. This is on the one hand, and on the other hand, how does waste recycling contribute to achieving environmental sustainability.
All contributions and responses are accepted from you with appreciation
In 2017 more than 11.4 million tons of solid glass waste was produced.Since the last 3 decades glasses have been used in many construction elements mainly in GFRC. While using the glass, the glasses cant be directly used in the construction process and first it needs to be molded into shapes and size and nature as required. While adding chemicals to the glass or while melting the glass to give different shape and sizes what further effect will it carry? Is it possible to complete eradicate the solid glass waste either by recycling or by using it as a construction material? And also can glasses replace the aggregates or sand?
In the case of water splitting the water oxidation (OER) is the bottleneck for the process and because of the harsh conditions of the WO reaction, molecular catalysts with high TOFs are not stable in the matrix and quickly decompose. On the other hand heterogeneous catalysts are more stable but they often do not have high TOF quantities. Now what is your opinion about the future catalyst type? Will the ideal catalysts fabricated by turning the molecular catalysts to heterogeneous catalysts ( by loading the molecular catalysts on the solid surfaces ) or it will be from the single atom heterogeneous catalyst type?
Plastic is now integral part of our life. Plastic industry is growing with a lot many Environmental problems.
We have various options and technologies but each one has its own merits and demerits.
1. Is it possible to ban plastic? The answer may be a big No.
2. We may ban a particular type of plastic? If yes, what type of plastic could be banned?
3. Reduce it use? But the problem will be there again.
4. Recycling is one good option but not cost effective.
5. Biodegradable plastic is one attractive alternative but not practical or may be very expensive?
In such situations what may be recommended?
Will waste segregation, recycling and ecological innovations solve one of the biggest civilization problems of the 21st century, which are rapidly growing landfills?
The problem of garbage appeared in the history of the development of civilization relatively late, because only in the nineteenth century, when the first industrial wastes, including petroleum plastics, began to appear.
Previously, it was dominated by the almost complete biodegradation of waste and the recycling of secondary raw materials.
The problem of growing waste heaps and landfills of unsorted municipal waste gradually grew in the 20th century with the development of industry.
The development of the industry was not burdened with almost any costs of environmental protection, cleaning up degraded environment, recovery of recyclable materials from waste.
Proecological concepts of industrial development, waste segregation and recycling have emerged and are practiced on a larger scale mainly in developed, richer countries, because these countries usually produce the most waste but also have financial resources for pro-ecological activities, waste segregation and recycling.
Technological, ecological and material innovations should help in the future to reduce the growing landfills of unsorted municipal waste.
One of the key problems of growing garbage dumps is still plastic, which is not subject to rapid biodegradation.
One of the solutions introduced in some countries is, for example, replacing plastic cutlery and plates in cutlery restaurants and dishes made of rice, bran or other types of cereals.
In addition, the complete elimination of plastic bags used to pack different products on paper or other organic biodegradable materials.
Gradually more and more restrictive solutions will appear. A lot of pro-ecological actions in this matter have been inspired by the above-national rock in the European Union.
But this is just the beginning of this process. The question arises whether the emerging new technological solutions, including ecological innovations, will solve this growing problem?
Will this problem be solved only when pro-ecologic activity begins to be a profit-making activity and not one that needs to be paid for?
But even if the next new technological solutions in the field of substituting plastics with other biodegradable materials, the innovations of ecological innovations that improve the recycling and reclamation of fugitive environments, would gradually solve the problem of growing landfills of unsorted landfills, will a man in this technological progress manage this problem? solve in the XXI century?
Will there be enough time for that? In addition, in poor countries, slowly growing for many years, this will be a serious problem.
These countries are illegally transported un-sorted, unprotected, often very toxic wastes.
In recent years, organized criminal groups have been involved in the practice of smuggling toxic, unprotected waste from rich, highly developed countries covered by restrictions of expensive segregation and neutralization process, securing, proper storage of toxic, non-recultivated waste to poorer countries, not subjected to such high restrictions or in which environmental protection and internal security systems do not work well.
In addition, there is a growing problem of sinking this type of waste in the seas and oceans. This process generates a rapidly progressing process of pollution of sea water and fauna and flora living in the seas and oceans.
In view of the above, the current question remains: Will waste segregation, recycling and ecological innovations solve one of the biggest civilization problems of the 21st century, which are rapidly growing landfills?

Despite green market thinking being here formally since 2012 Rio +20 conference finding a definition of a true green market is hard to find even in major publications dealing with green growth and green economies…the term green market a kind of disappeared as we moved towards an environmentally friendly world after 2012, and because it was left unattended in development and economic thinking circles this has led since then to confusion and misused of the term.
Many forms of environmentally friendly markets are called green markets, when they are not. For example, a Google search of what is a green market leads to the following definition in Wikipedia:
--The term "green market" refers to the fact that the resold goods are put back into productive use, which is the most environmentally friendly use of used or discontinued products--
But that is a definition of one type of environmentally friendly market, but that is not the definition of a green market. And this lead to the questions, what is a green market? What is not a green market?. Please feel free to comment, what do you think a green market is and/or what it is not; and why?
How to properly dispose of cigarette butts and ash in the garbage?
I risk poisoning all safe household garbage with dangerous nicotine. In addition, the cigarette butts are very small and light and can be scattered from the landfill by the wind. My city doesn't have a program for recycling cigarette waste, but how can I safely throw cigarettes in the general trash? I've seen the advice on the internet to pack this garbage in a separate dense bag. But I need expert confirmation.

I suspect a similar question would be 'How long is a piece of string?
Is toilet paper a western phenomenon only?
Given the apparent lack of toilet paper in supermarkets, it seems pertinent (or impertinent) to ask how long a roll (of given number of sheets; ply etc) would last an 'ordinary' family or person.
Can both sides be used? Can the material be recycled?
What alternatives to toilet paper are there?
What leaves would you avoid (e.g. poison ivy)?
Is there a database for toilet paper usage?
How much can be hoarded before it overwhelms a family?
This is a question that keeps popping up in the textile and apparel industry. My understanding is that when heat is added, iterations of the polymer are degraded. I'd argue that there is a lot of potential in harvesting and recycling plastic waste, however given our current recycling system and techniques, we are far from achieving circularity or "closing the loop" via recycling plastic.
In most developing countries like Nigeria, low to medium-income earners consume packaged water coming from sachet water. Sachet water is made from LDPE. I am looking at each packaging holistically from LCA, ease of recycling to how much useful products can be recovered from it through recycling.
However, what I find is that the papers on these are rather focused on other things than what I would like to know. For example, while there are several papers on pyrolysis of LDPE, most are focused on the viability of the process and characterising or quantifying the yield. None compares their endproducts gotten from PET or HDPE with LDPE and so on, to highlight the importance of one alternative over the other. So I would appreciate if someone can outline some of the issues associated with each or point me to some resources to get clear guidance on the advantages and pitfalls of each beyond the fact that LDPEs get stuck to machines during recycling.
Ultimately I will like to bring clarity to a question like should the Government ban a product like sachet water because it qualifies as a single-use plastic and is made of LDPE which has the lowest value when recycled compared to alternatives like HDPE or PET?
I am kindly asking for the information about what kind of solution is implemented to recycle diapers in your country / community?
