Waste Management - Science topic

THANKS MR JASON

Waste management programs have become a significant political promise in EU countries due to a combination of environmental, economic, social, and regulatory factors. Here’s why:

1. Environmental Concerns

2. Economic Implications

3. Social Pressure and Public Awareness

4. Regulatory Pressures

5. Urbanization and Infrastructure Needs

6. Electoral Strategy

Political parties use waste management programs to demonstrate environmental responsibility, economic foresight, and responsiveness to citizen concerns, aligning with broader EU goals while appealing to voter priorities.

To answer your question, it's important to consider the context and objectives of the vote. If the issue relates to the environment or waste management, I would generally support decisions aimed at more sustainable resource management and minimizing negative impacts on nature.

Reasons for support include:

Of course, the specific answer depends on the details of the proposal and how it will be implemented in practice. If the proposed measure is considered effective and sustainable in the long term, I would be inclined to support a vote in favor of it.

greats help, thanks Mr Abhijit

thanks You, Mr Abhijit, so Why do some political parties in the Netherlands use environmental issues and How do political parties define their political issues?

thanks

Sure, and that should be the priority. Have a look at some practices in the article.

Ayesha Khan sustainable development waste management seeks to balance economic growth with environmental protection and social equity. It aims to reduce waste generation, promote recycling and reuse, and divert waste from landfills. This approach not only protects natural resources but also creates jobs and contributes to a healthier, more sustainable future.

Dear college,

In the determination of platinum group of elements in Pt catalyst samples can be used different decomposition procedures.

Please, pay attention, that the analytical evaluation function is assumed to be straight line through the origin. There are is not spectral interferences. But the correct calibration from the point of view of multiplicative interferences means a precise matching of the acid in both the reference and sample solutions.

I recommend the decomposition procedure in the determination of platinum group of elements in Pt catalyst samples because the platinum group of elements must be dissolved in aqua regia, but in the end of the dissolution procedure, the final sample solution contains Pt, Pd and Rh in hydrochloric acid only in an appropriate acidity, because the undissolved material (γ-alumina+silicates) has settled down. Under these conditions you must prepared the calibration solutions for Pt, Pd and Rh with hydrochloric acid in an appropriate acidity.

With kind regards, N. Daskalova

Waste-to-energy (WTE) is a process that involves converting various types of waste materials into usable forms of energy, such as electricity, heat, or fuel. This is typically done through various methods including incineration, gasification, and pyrolysis.

Here are some key technologies used in waste management:

1. Incineration: This process involves burning waste materials at high temperatures to produce heat, which is then used to generate electricity or steam. The remaining ash can be disposed of in a controlled manner.

2. Gasification: Gasification converts solid waste into a gas mixture called syngas by heating it in a low-oxygen environment. The syngas can then be used to generate electricity, produce biofuels, or as a chemical feedstock.

3. Pyrolysis: Pyrolysis is a thermal decomposition process that breaks down organic materials in the absence of oxygen, producing bio-oil, syngas, and char. These products can be used for energy production or as feedstock for various industrial processes.

4. Anaerobic Digestion: Anaerobic digestion is a biological process that breaks down organic waste materials in the absence of oxygen, producing biogas (primarily methane and carbon dioxide) and digestate. Biogas can be used as a renewable energy source for heating, electricity generation, or vehicle fuel.

5. Landfill Gas Recovery: Landfill gas, primarily methane and carbon dioxide, is generated as organic waste decomposes in landfills. This gas can be captured and used as a renewable energy source for electricity generation or heating.

6. Mechanical Biological Treatment (MBT): MBT combines mechanical sorting and biological treatment processes to recover recyclable materials from mixed waste streams and stabilize organic waste for further treatment or disposal.

These technologies play a crucial role in waste management by reducing the volume of waste sent to landfills, recovering energy from waste materials, and minimizing environmental impacts associated with waste disposal.

Yes, very correct because various kind of waste under mesophilic temperature provide and enhance the activities of bacteria even before the waste get to the gut of the worms. In this regards, waste deposition from vegetables, fruits, waste food without salt can be minimized. Vermicompost maybe but not to a large extent because the worms may die if the environment is toxic instead of producing compost.

In any organization, Waste generation is associated with multiple stages in the supply chain starting from the process used for raw materials generation to the waste generated by the end users/customers. You can manage the waste by supply chain management. by cutting your carbon footprint, establishing upstream and downstream reporting, and ensuring waste management programs are optimized. Waste reduction is crucial to supply chain management since it affects the system's effectiveness and efficiency. These can also help boost your ESG (Environmental, Social, Governance) score. Poor Inventory Management: Inaccurate inventory tracking can result in products expiring before they are sold. The main cause of waste pollution is poor waste management. We must take into in mind that waste is not the material, but the way it is managed. For example, a piece of paper will be waste or raw material depending on how it is managed. Green supply chain management (GSCM) involves sustainable environmental processes built into conventional supply chains.

Dear Jorge,

Thank you for your comments. I agree that we should continue to research air pollution. My focus is on human health but there are also implications for more than just health. Thinking more broadly, the concept of sustainable cities comes to mind as well as essentials for human existence and potential interaction with air pollution such as its impact on Maslow’s Hierarchy (some question this, I however, believe it to be still relevant).

One of the objectives of the educational institution is to spread, develop and continuously improve education, and to establish high-level scientific, cultural, professional and social bases. Educational institutions must move towards being flexible organizations, to be able to respond quickly to change, and to build best practices in a rich and sustainable knowledge environment.

Yes, there is an accepted taxonomy or categorization of environmental issues. Environmental issues can be broadly categorized into several key areas, and these categories help organize and address various challenges related to the environment. Some of the major categories of environmental issues include:

These categories are not mutually exclusive, and many environmental issues are interconnected. Environmental scientists and organizations often use this taxonomy to study and address specific challenges and develop strategies for environmental conservation and sustainability. Additionally, new issues may emerge as our understanding of environmental systems and their interactions evolves.

The most accepted guideline for waste management plans in veterinary hospitals and veterinary laboratories can vary by region and jurisdiction. However, there are common principles that are widely recommended and followed. The primary goal is to ensure safe handling, proper containment, and responsible disposal of different types of waste generated in these facilities. These waste types typically include general waste, hazardous materials like chemicals and pharmaceuticals, infectious waste, and sharps. Proper segregation, labeling, and storage of waste are emphasized to prevent contamination and safeguard both human and environmental health. Compliance with local regulations and standards is crucial, and staff members are usually trained to follow established protocols diligently. By implementing comprehensive waste management plans, veterinary facilities can minimize potential risks associated with waste disposal and contribute to environmental sustainability

Any residue that contains a high percentage of VTS, pH around 7 and balanced TOC/NTK ratio, can be submitted to the composting process and then to vermicomposting.

Very interesting discussion there Samuel...

Following the discussion, I strongly believe that these points could be of a greater help.

1. Incorporating the ‘Extended Producer Responsibility’ (EPR): The EPR principle requires the producers to take responsibility for the entire life cycle of the product. This approach is expected to reduce plastic waste by providing incentives to producers to design products so that they are recyclable and reusable.

2. Promoting the ‘Circular Economy’ (CE): The CE is a system that focuses on reusing, refurbishing and recycling products. This approach will reduce plastic waste by encouraging consumers to purchase products that are ‘closed loop’, meaning that the products are designed in such a way that their components can be recycled or re-used.

3. Encouraging ‘Zero Waste’ Development: This approach focuses on reducing waste by using renewable energy sources and encouraging the reuse of materials. This can be done through promoting the use of renewable energy sources, such as solar and wind power, as well as encouraging the use of reusable containers and packaging.

4. Promoting the ‘Polluter Pays Principle’ (PPP): This approach requires those who produce pollutants to pay for their own clean-up costs. This will encourage producers to design products that are less harmful to the environment and reduce the amount of plastic waste generated.

5. Facilitating ‘Producer-Consumer Partnership’: This partnership focuses on engaging producers and consumers to work together to reduce plastic waste. This can be done through marketing campaigns that promote the use of reusable containers and packaging and encouraging producers to design products that are more sustainable and less wasteful.

6. Establishing ‘Plastic Waste Management Programs’: These programs will focus on creating awareness about the hazards of plastic waste and encouraging the use of alternative materials. This can be done by providing incentives for people to switch to reusable materials and providing educational resources on the proper disposal and reuse of plastic.

7. Promoting ‘Green Procurement’: This approach focuses on purchasing products that are sustainable and environmentally friendly. This can be done by instituting green procurement policies and providing incentives to producers to design products that are more sustainable and less wasteful.

8. Developing ‘Local Waste-to-Energy Systems’: This approach focuses on using the energy produced from waste to generate electricity. This can be done by converting plastic waste into fuel or using plastic waste to generate electricity. This will reduce the amount of plastic waste that is going to landfills and reduce the amount of energy needed from other sources.

Thank you.

To get impact of economic growth of waste management, need society participation and society awarness. In indonesia, we have a program that we called "waste bank". In the waste bank, waste from households should be separated and collected such as : paper, plastic and other waste can be recycle.

The waste that collected from waste bank can be sold to waste collector and the revenue from that transaction can gived to the society.

Digital twins could be highly effective in the context of carbon neutrality and energy consumption reduction in the home sector. By leveraging the power of data, digital twins can provide an accurate picture of energy consumption and allow homeowners to take proactive steps to reduce their energy consumption and emissions. For example, digital twins can create detailed energy models of individual homes, track energy usage in real-time, and provide insights into how different energy-saving measures can impact energy consumption and emissions. Additionally, digital twins can also help homeowners optimize their energy usage by providing personalized recommendations and alerts. Ultimately, digital twins can be used to empower homeowners to make better decisions about their energy consumption and reduce their carbon footprint.

One manifestation of material 'upcycling' can be 'chemical recycling'. Recent studies have been published by companies like BASF, Plastic Energy, and independent think tanks like The Consumer Goods Forum that will be useful to read for this.

Dear Researcher.

Adding to information on odour removal or neutralisation is best done

Hi Thalita Laua Reis Campos! Thank you very much for participating in this discussion. I believe that TBL is essential for the development of solid waste management. In my vision, I suggested that it should be an indirect action because it doesn't directly operationalize waste treatment and disposal, but with actions that could improve its impacts on the environmental level (as in the case of developing awareness campaigns), social level (as in campaigns that encourage the exchange of waste for food), and economic level (encouraging the structure of the commercialization of recyclable items, so that the collectors can have better profit margins and can dedicate themselves to the activity because they are key players in the reduction of waste). In the case of Environmental Solution, I classified it as direct, because this pillar deals directly with the operationalization of waste management, such as thermal or biological treatment plants or the use of waste to produce renewable energy. But anyway, this is just an opinion in which I am analyzing its consistency, and the insights that you are providing me are very important. Best regards!

Hi Wissam, I think there are two approaches to treating organic waste to convert it into fertilizer depending on the waste composition. If the waste N content is high (animal protein) directly convert to fertilizer using common composting techniques, if not first feed to an anaerobic digester and collect the methane and use it as a fuel. The waste generated from the digester is a fertilizer.

Tamjid Us Sakib depends on the type of technology selection and project

microlage is preferred in case of biological and if you have space and time with low cost investment however if you go via chemical route there are many like activated carbon, haaluminum sulphate or few other sales can also be used

The transition to a circular economy is not uniform and varies depending on a series of factors such as the degree of industrialization, the level of technological development, the availability of qualified human resources and access to financing, among others.

Dear Rishi Singh,

In my opinion, the most relevant research topic on plastic waste management in the face of global warming and environmental degradation may be to analyze the possibility of launching the mass production of biodegradable plastic substitutes of organic origin for the packaging of various products as well as fast moving products with a short shelf life.

Best regards,

My personal favourite journal is the Journal of cleaner production and ESPR.

The first step in integarating BIM from design to construction stage is to use one of the software such as Revit, Teklastructures, digital plan and many others for 3 Dimensional representation of the project, these software can be integrated with other software for example can be integrated with robot structural analysis for design and analysis of the structure, with Primavera for scheduling, with Navisworks for construction simulation and clash detection before starting the construction process. this will help visualizing the project for the stakeholders, engineers and project managers and prevent any change orders during the construction phase. Also, clash detection prevent any sudden technical problems during construction which reduce construction waste to great extent.

Dear Prabhat Ranjan,

Yes, the process of global warming is causing disturbing environmental changes also in the Arctic zone.

Dear Ade Brian Mustafa sorry to see that your interesting technical question has not yet been answered by experts. As an inorganic chemist I'm ansolutely not an expert in this field, and personally I never used this software. I assume that you already checked all handbooks and tutorials which are available on the gabi-software.com homepage. Pease also have a look at the following freely available handbook:

This manual is freely available as public full text (see attached pdf file).

It might also be worth having a look at the answers given to the following closely related question which has been asked earlier on RG:

I also suggest that you search the "Publications" section of RG for terms matching your question, e.g.:

I hope this helps. Good luck with your work and best wishes!

Salam Mr. Mohammed.

It's a quite general question. You need to provide more details regarding the nature of this solid waste.

Initially, you need to identify the source of waste, in which are these wastes from agriculture or industrial industry? * This is basically to identify the next step.

If the waste is from the agriculture industry, you need to run a XRF, TGA, LOI analysis to understand the carbon content, chemical compositions.

The wastes generated from the agriculture industry are usually fed back into agriculture activities (e.g. as fertilizer). However, with some treatments, it could be utilized in different industries.

The second case is to be generated from industrial activities, mainly mining and oil extraction activities. In this case, the most important characterization analysis you need to conduct is the XRF analysis. Indeed, you need to assess the value of this waste and what elements could be re-extracted from the waste before it can be processed in different activities.

In short, my opinion is like that, you need to provide more information about the targeted waste and its source. Based on the source and nature of this material, specialists in their field could recommend either a standard or references to characterize the waste materials based on their perspective.

My colleagues discussed the topic well above, but I want to discuss it from another point of view: There are those who abuse the concept of "protecting the environment" so they sell you, for example, a phone for a large amount and does not give you the charger with the phone box, claiming that it preserves the environment even though it took a large amount from you and you will have to buy the charger So you will have two cans to throw in the trash.

I think you mean to say the amount of emission by pharma sector. There is no study available but pharma industry is one of the major contributor of pollution. Pharma market is 28 per cent smaller yet 13 per cent more polluting than the automotive sector

Challenges in waste management - Nigeria are mentioned herewith in the link

although it is very interesting question but I think its quite hard to put a percentage on it.

Thank you all for your responses. I do not really understand one thing. Why would the government not want such issues to be addressed? What is the problem? Is it a monetary issue? If yes, then where does the public have a say in forming or reforming policies like these for the overall betterment of society?

There are various issues with the construction and demolition waste like:

1. Quantity of waste generation is huge

2. These waste is dumped in landfills and now it is falling short

3. New technologies and regulations are required to reduce, recover and recycle this waste

Dear Elhassan,

The current stage of the BIM learning curve and maturity allows construction practitioners to design out both wasteful practices (lean) and solid waste at the design stage. It is definitely a great area of research because construction waste have significant negative implications on cost, society and the environment.

Depending on your research capabilities and availability of data, you may measure, quantify and monetize the quantity of solid construction waste footprint that can be reduced due to the use of BIM in the project. Of course, you would have to compare two or more similar BIM and non-BIM construction projects. Your greatest challenge will be to determine the reduction attributable to solely BIM since lean production principles and offsite industrialized solutions have proven to reduce solid construction waste in projects.

You may search the following paper to use as a good starting point

"How to measure the benefits of BIM" by Barlish and colleague and published in the Journal of Automation in Construction
