Questions related to Recycling
Which mixing approach is the best for producing recycled concrete ? in term of performance, cost and time ?
Are there technologies available to produce biofuels based on organic compost, from organic crop waste, that could serve as engine fuel to power tractors and other agricultural machinery in sustainable, organic, pro-environmental, pro-climate farming?
In recent years, in connection with the inclusion of the agricultural sector in the process of green transformation of the economy as well, new solutions are being sought, created and implemented to enable the transformation of productive farms into sustainable, pro-environmental, pro-climate, organic farms growing crops and other aspects of agricultural activity in accordance with the principles of organic farming and with the simultaneous implementation of sustainable development goals. Accordingly, on a farm operated in accordance with the formula of sustainable organic agriculture, pesticides and other chemical pesticides and chemically produced fertilizers are not used in agricultural crops, energy is obtained from renewable and emission-free energy sources, water is obtained mainly from rainwater catchment facilities, organic manure and processed organic waste from composters are used to fertilize farm fields, crop rotations are used within the framework of multi-year cycles to restore high soil quality and prevent soil aridity, individual farm fields are separated by green belts and flower meadows to provide foraging areas for pollinating insects, on-farm mini-treatment plants are built to treat wastewater generated on the farm and not used in a specific way for farm purposes, etc. Besides, on a farm run according to the formula of sustainable organic farming, available technologies for the production of biofuels based on organic compost, from organic waste from agricultural crops, through which motor fuel is produced to power tractors and other agricultural machinery, should be used. These may include the construction of biogas plants, where biogas can be produced, which can then be used to power agricultural machinery. Besides, in a sustainable, ecological, pro-environmental, pro-climate farm, agro-tourism activities may also be developed, and certain preserves, food products, such as jams, juices, cheeses, etc., may be produced within the framework of a micro-production activity or manufactory, within the framework of local brands on the basis of organically produced, cultivated crops. In addition, such sustainable, organic agritourism farms may be associated within a local producers' cooperative with silos, warehouses, etc. in which crops from the cultivation of several or more locally operating farms and/or agritourism farms are stored, including or mainly, only those operating under the formula of sustainable organic farming.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
Are there technologies available for the production of biofuels based on organic compost, from organic crop waste, which could be used as motor fuel to power tractors and other agricultural machinery in a sustainable, organic, pro-environmental, pro-climate farm?
Could biofuels from agricultural waste be used as engine fuel to power tractors in sustainable organic farming?

Hello, This is Romesha & I am working on a research project based on Reduce, Recycle & Reuse Wastes in Hospitals. So should i add the AI factor to improve the system more effectively or leave it for the way ahead?
Can recycling materials lead to environmental sustainability and recycling process of waste have any impact on the environment?
I want to apply green supply chain process to reduce, reuse & recycle wastes which I think is a very critical case for hospitals.
Hi All
How is chemical recycling of composite materials done in Simapro?
How does the uniqueness of each sperm relate to the probability reincarnation? The fact that each sperm fertilizing the egg results in a different individual being conceived, and then maybe born, causes reincarnation to fall in probability. The recycling of consciousness(the theme of reincarnation) is further lowered in probability by the uniqueness of each sperm. Also each sperm, forming a completely different individual than another sperm, creates a completely different consciousness than another sperm would have. How could someone who had died have their consciousness recycled through the genitals of others? Thus, the uniqueness of each sperm( and the randomness of which sperm fertilizes which egg) causes reincarnation to be a less parsimonious explanation of the afterlife than heaven without reincarnation is.
How can we maintain environmental sustainability and what are the effects of recycling and reuse for environmental sustainability?
Currently, I am studying related to integrated assessment model for modelling of plastic waste recycling using system dynamics approach. The factors will be considered in model framework are environmental, economic and material performance (mechanical properties). I am still confused, how to evolve the last factor (mechanical properties) in System dynamics. Anybody has the experience related to the similar case?
Thank you in advance.
A lot seems to be coming out in publications about the circular economy or sustainable development and the circular economy or circular economy and sustainability or circular economy, sustainable development and global warming...and so on.
All researchers and publications seems to have the same theme of directly or indirectly indicating that the broken circularity traditional market economy can be made circular by non-green market means; and hence, they advocate circularity without indicating where the circularity problem came from or comes from; hence, without indicating whether they are fixing a broken circularity problem or patching that broken circularity problem plus their circularity thoughts seem to be disconnected from the need to one day transition away from the pollution production based economies to the pollution free economies....
They seem to start with addressing the consequences of the broken circularity problem without any regards with respect to fixing the root cause of the broken circularity problem.
And this raises the question, Can you have a circular green economy without green markets? If No, why No? If Yes, why yes?
What are the 5 R's of waste reduction and what are the habits we can adopt to reduce waste and promote recycling?
Is recycling green marketing and how does green marketing affect consumers andchallenges of green marketing?

How matter is recycled used over and over again in an ecosystem and why does energy flow but matter is recycled?
Remark_1: science is not only about publishing papers dealing with problems that are acceptable (well seeing) by the "normal" academic canon or, on the other hand, with problems that are, relatively speaking, much easier to solve or, at least, it is not highly complicated to try to "solve".
Remark_2: scientists from the developing world, regardless the discipline, might start thinking farther on what does the "hard" Sustainable Development (SD) version mean for their countries, and how bad is to replicate (to support) discourses that comes from communities (whether interested stakeholders, nations, international organizations, think-tanks...) that want to keep the high rates of economic growth regardless any physical, ecological, and climate-based constraints. Much to my regret, there is a concerning amount of advocates to such an approach (outer-space mining) in Latin America as a whole... We need to rethink what development is all about and what will be the fate of the Latin American nations under such sustained trend of a lack of governance of the outer space domain.
- Is it really necessary to go far beyond Earth atmosphere to carry out very risky outer-space mining activities...?
- Why specific sectors are pushing for investing in the outer space mining when it is highly visible and measurable (at naked eye) the amount of thrash that it is piling up and surrounding all cities in the world...?
- What about the amount of metal, plastic and other "strategic" material (including wood/timber) that should be recycled at great scale in all continents and regions in the planet...?
- What education policies should transfer the current effort aimed at funding already useless careers and titles to empower the next generation of skilled workers, technicians, and experts in recycling al at levels of the society....? What impede that transformations in the labor force worldwide...?
- To the fans and advocates of the circular economy scheme: (1) have you already thought about the huge amount of energy that would be required for such a large-scale recycling (The thermodynamics laws always will matter despite economics could claim)...? (2) Shouldn't be a maximum number of human population that make circular economy feasible...? (Human population trends) are not in the equations of the hard SD version). (3) Do we (humans) have time for a step-by-step circular economy development (more action and less "floppy" business papers)...?
As I have pointed out in all my questions, the 2030 SDGs agenda is already compromised and no major advancement is being achieved regarding the speeding up overlapping and non-linear climate and Earth's ecology breakdowns, therefore, why humanity should embark in another wishful-thinking reckless economic push within the "New Space Economy"...?
As we keep trying to keep humans outside the equations..., all what be published regarding sustainability (science), governance, and the so-called cutting-edge research on Climate Policies and Action will be just a futile act of absolute incompleteness and despair.
Thus, I call scholars from all the disciplines to carry out their major effort in adding the humans into their equations (schemes, models) and start writing as we are the root of the current problems , but also the solutions to those human-sparked messes... A major shift must be empowered in the way science is made... Science has being under crisis for twenty years or so... We all know by 2000 the problem will be greater and will advance faster than our potential response as a species... All has been an unprecedented large-scale denial...
Willing to interact to write more realistic (with policy implications) papers and for teaming (network-building) in searching for implementing sound "cutting-edge" research proposals whenever funds will be available.

Hernan L. Villagran
How do nutrients move through biotic and abiotic parts of an ecosystem and why is it important for matter to be recycled in ecosystem?
Is energy recycled in the biosphere and matter recycled within and between ecosystems?
Is energy recycled through Earth's ecosystems and how energy flows and chemical recycling in ecosystems?
In which stage would minerals be added during the formation of soil and recycling of matter between living things in the environment?
How does energy get transferred and recycled within an ecosystem and energy recycled through an ecosystem why or why not?
When addressing the socio-environmental challenges associated with the traditional economy mainstream researchers and organizations start from the point of view "Our current economy is linear” “ The economy of the future is circular”, taking the position that linearity is the root cause of sustainability problems, see for example: https://www.metabolic.nl/what-we-do/circular-economy/?gad=1&gclid=CjwKCAjwpJWoBhA8EiwAHZFzfoJkA5YMY6R6Crk_hIVmoam5SZZ8zjojNJOsh6PgMWygbt0t8LV8TRoCupMQAvD_BwE
They seem to be doing this without asking themselves the question, why is the current economy linear? Since when it has been linear? Could not be that the root cause of that linearity is the root cause of sustainability problems? If this was the case, then addressing linearity by going circular a la traditional market still leaves the root cause of the problem untouched and active.
And this raises the question: Is economy linearity the root cause of social, economic, and environmental challenges? If yes, why?. If not, why not?

As the demand for sustainable energy solutions continues to surge, the importance of battery recycling has never been more evident. Batteries power our lives, from mobile devices to electric vehicles, and their responsible disposal is a pressing concern. 🌍
However, the path to effective battery recycling is not without its challenges. One of the key hurdles is the diverse range of battery chemistries and designs. Each type requires a unique recycling process, making it complex and costly to handle them all efficiently. ♻️💡
Additionally, the shortage of specialized recycling facilities and infrastructure poses a significant challenge. Developing proper collection, transportation, and recycling systems is crucial to prevent improper disposal and environmental damage. 🚮🌱
Technological advancements are crucial in overcoming these challenges. Innovation in battery design for easier disassembly, improved sorting techniques for better segregation of materials, and refining recycling processes can all contribute to a more sustainable future. 🛠️🔬
Any conversation starters about current gaps in the industry?

Hello everyone friends
Is the issue of recycling TetraРak packaging relevant now? What do you say about the production of composites from ТetraРak?
Thank you very much
According to the Regulation, issued by the Commission Regulation (EU) 2017/833, it is not allowed to produce insect biomass on manure and catering wastes. Is it because of potential contamination of these wastes with deleterious chemicals, like pesticides, antibiotics, and endocrine disruptors (which can be applied in farming processes and in kitchens), or because of potential contaminations with pathogens, which is common for agricultiral animals and human? This legislative restriction significantly reduce the opportunity of the recycling of the valuable compounds (fat, amino acids etc.) from the by-products. So, I want to understand, what can we do in order to make the by-product save for recycling by means of insects, earthworms and other invertebrates? For instance, we can use manure from animals, which are free from pharmaceutical usage (I mean veterinary treatments), or we can thermally sterilize the by-products to prevent the propagation of human pathogens.
What do you understand by the adaptations in organisms and why do they adapt and types of organisms recycle nutrients in a food web?
Gasification and pyrolysis are two thermochemical processes that are compared for plastics recycling. Gasification breaks down solid waste into simple molecules, mainly CO and H2, which can be converted into value-added liquid chemicals through catalytic synthesis processes. This route is preferred for its ability to produce several key petrochemical products in high yield. Pyrolysis, on the other hand, involves the conversion of plastics into liquid fuel. Catalytic pyrolysis of homogeneous waste plastics produces better quality and higher quantity of liquefied fuel compared to non-catalytic pyrolysis at lower temperatures. The pyrolysis process allows for the transformation of plastic mix into profitable liquids, gases, and solids, with the composition of the plastic waste affecting the products obtained. Both gasification and pyrolysis offer potential solutions for plastic waste recycling, with gasification being favored for its ability to produce high-value petrochemical products and pyrolysis being effective in producing liquid fuel from plastics

In the context of the human-induced accelerating process of global warming, the increasing scale of environmental degradation, the extinction of many species of flora and fauna, the decline in the biodiversity of the planet's natural ecosystems, people are increasingly asking themselves: where do you think each of us can start in terms of protecting the climate, nature and biodiversity of the planet?
A key premise for formulating such questions is the adage that a drop beats a rock. Often, when we wonder whether to choose a bicycle instead of an internal combustion car as a means of transportation in a situation of driving to a nearby store, the answer appears that, after all, with this one gesture, this action performed only by us in a situation where many other people, including neighbors, friends, etc. do not do it, we ourselves will not save the climate and the biosphere. But, after all, this is what many people think. And each individual, if this thinking would change and replace the car with a bicycle then one drop will turn into thousands and then into millions of drops, into rain, into a river and large-scale changes will be realized. The same applies, for example, to the issue of segregating waste, to the use of pesticides in the home garden, to the creation of a flower meadow instead of mowing the lawn, to changing consumption habits to more prudent and sustainable ones, on the reuse of used products and recyclables in the sharing economy, etc. Of course, green financial subsidies, regulatory change are key instruments to motivate this kind of change, to systemically address the issue of smoothly carrying out the green transformation of the economy to build a sustainable, zero-carbon, green closed-loop economy. However, the adage that a drop drills the scale is valid. In this regard, it is particularly important to change the consciousness and mentality of individual people individually and, at the same time, of many people in society.
In view of the above, I address the following question to the esteemed community of scientists and researchers:

How to solve the problem of illegal toxic waste dumps, which contribute greatly to environmental pollution, threaten the biosphere and the health of people, local residents?
In some countries, especially poorer developing countries in recent years, the scale of the problem of illegal toxic waste dumps, which greatly contribute to environmental pollution, threaten the biosphere and the health of people, local residents, has grown. The problem is caused, among other things, by the low scale of waste segregation and recycling and the illegal import of toxic waste from other countries. This illegal practice has become one of the most profitable illegal businesses run by organized crime groups. Some of the illegal toxic waste dumps become fires after some time, in whose combustion processes toxic, carcinogenic, carcinogenic chemical compounds that are harmful to human health are formed and enter the atmosphere, soil and water. In addition, some illegally created toxic waste dumps, before they become a source of dangerous fires for the environment and human health, can also be a source of pollution of the surrounding groundwater, subsoil and surface water, if the landfill was created without adequate protection of the land on which it was created. This problem also affects the country in which I operate. I am very much asking for your recommendations, advice, recommendations on how to solve this problem. I ask for publications that describe the results of research on this issue and recommendations for solving this serious problem. What are the practical and effective solutions to this problem used in various countries? What technologies should be used to dispose of illegally stored toxic chemicals? What changes in national legal norms should be applied to effectively reduce to a large extent the scale of the aforementioned practice of creating more illegal toxic waste dumps? How should environmental and waste management policies be improved? How to increase the scale of waste sorting and recycling? How to increase the scale of development of sharing economy? How to solve the problem of illegal toxic waste dumps, which greatly contribute to environmental pollution, threaten the biosphere and the health of people, local residents?

Is an economics model based on the concept of sharing economy an essential element of a sustainable circular economy?
Is the sharing economy model an essential element of a sustainable circular economy and an important factor in protecting the climate, biosphere and biodiversity of the planet's natural ecosystems?
Is the sharing economy model an essential element of a sustainable circular economy and thus a sustainable green zero-carbon economy or one that strives for zero-carbon, green transformation of the economy, protection of the climate, the biosphere and the biodiversity of the planet's natural ecosystems?
The sharing economy model, i.e. the sharing economy, the sharing economy, the collaborative economy, is an important element of what is more broadly referred to as a sustainable circular economy. On the other hand, the processes of green transformation of economies aimed, among other things, at reducing the consumption of natural resources, decreasing waste generation and decreasing greenhouse gas emissions are expected to lead to a reduction in the scale of carbon emissions, i.e. greenhouse gas emissions and thus slow down the progressive process of global warming and reduce the scale of environmental pollution, reduce the scale of loss of biodiversity of natural ecosystems and the consumption of strategic natural resources such as water and rare raw materials. The phenomenon is based on people's willingness to cooperate, help others and share their time and resources, which is reciprocated in various ways (material and non-material). In the past, this form of cooperation was limited to a narrow circle of family, friends and neighbours, and with mass production, the development of trade and services and stronger migration resulting in the separation of multi-generational families and the loss of networks of acquaintances, this phenomenon slowly lost its importance and its functions were taken over by companies and institutions (e.g. public institutions). The other side of human nature, which is the desire to compete and look after narrowly defined self-interest, is the basis of classical economics, but under market economy conditions it sometimes leads to distortions (exploitation, fraud, etc.). Thanks to the development and application of new technologies, collaborative economics is once again gaining popularity and economic rationality. A key determinant of the dynamic development of the sharing economy was the financial crisis in 2008, as well as the need to save money, make better use of resources and change social relations. The development of the concept of a sustainable circular economy should therefore also take the sharing economy into account. The circular economy takes into account, among other things, the minimisation of the environmental impact of the production cycle. An important element of the closed loop economy can be the production method called in Polish 'from cradle to cradle'. This idea specifies methods for designing and producing objects in accordance with the concept of sustainable development, so that, at the end of their useful life, they can be put back into the production cycle. The circular economy also has a territorial dimension. In the context of the functioning of regions and especially urban areas, it refers to yet other economic solutions, e.g. the concept of the sharing economy, according to which unlimited consumption or accumulation of property gives way to sharing, exchanging or borrowing. According to this concept, people give up many goods for their own exclusive use in favour of others, i.e. they reduce the need for products whose production cycle often requires large amounts of raw materials and energy. The sharing economy is defined as a social and economic phenomenon that involves a shift in organisational and distribution models towards distributed networks of interconnected individuals and communities, involving both the direct provision of services by people to each other, as well as sharing, co-creation, co-direction, etc., enabling a radical increase in resource efficiency. Accordingly, the sharing economy model is an essential component of a sustainable circular economy and thus a sustainable green zero-carbon economy or one that strives towards zero-carbon.
In view of the above, I address the following question to the esteemed community of scientists and researchers:
Is the sharing economy model an essential element of a sustainable closed loop economy and thus a sustainable green zero-carbon economy or one that strives for zero-carbon, a green transformation of the economy, the protection of the climate, the biosphere and the biodiversity of the planet's natural ecosystems?

How the flow of energy in an ecosystem justifies is unidirectional and how do decomposers help in recycling of matter to maintain balance?
What contrast movement of energy through an ecosystem with movement of matter & decomposition help in recycling of nutrients among their environment?
Why is decomposition important how does decomposition help the living and microorganisms in soil help recycle chemicals in dead plants?
Does movement of energy similar to movement of nutrients & microorganisms feed on dead & decaying plants & animals & recycle minerals?
Can cycling of matter different from flow of energy in an ecosystem & microorganisms in soil recycle carbon from leaves so carbon is used for plant growth?
