Mitigating greenhouse gases emissions in processing fossil carbon containing industrial waste
Researchers assessed best available techniques (BAT) for reducing greenhouse gas emissions from waste treatment of fossil carbon-containing materials including oil, plastic, and rubber. The analysis found that recycling is the primary recommended method, and that effective GHG mitigation policy requires integrating waste management with full product life-cycle optimization.
Optimizing plastics recycling networks
Researchers developed mathematical optimization models — including linear programming tools — to help plan efficient plastic recycling networks that can tolerate some contamination from mixed plastic waste streams. These models could help overcome a key barrier to large-scale recycling by intelligently matching waste sources with the plants best equipped to handle them.
Development of a Decision Support System Prototype for Time and Cost Reduction in Collecting Recyclable Waste
This study developed a decision support system to optimize routing for waste pickers collecting recyclable materials, reducing collection time and cost. Improving recyclable waste collection efficiency is important for diverting plastic waste from the environment where it would fragment into microplastics.
Optimization of Renewable Energy Supply Chain for Sustainable Hydrogen Energy Production from Plastic Waste
Researchers developed an optimization model for producing hydrogen energy from plastic waste in Iran using a renewable energy supply chain approach. They found that converting plastic waste into hydrogen fuel through gasification is economically feasible, with costs potentially decreasing over time as the system scales. The study presents a strategy for simultaneously reducing plastic waste volume and generating clean energy.
Reconciling Waste Management and Ecological Economics
Researchers examined how the concept of the "circular economy" — designing products and systems to minimize waste — fits within ecological economics, which emphasizes physical limits like energy and material flows. The chapter argues that effective waste management policies, such as landfill taxes, extended producer responsibility, and deposit-refund schemes, must align environmental costs with economic incentives to achieve meaningful sustainability gains.
Environmental Impact Assessment of Plastic Waste Management Scenarios in the Canadian Context
Using life cycle assessment, this Canadian study compared current plastic waste management against two alternative scenarios and found that shifting away from landfill-dominated disposal could significantly cut environmental impacts including greenhouse gas emissions. The findings underscore that how we manage plastic waste matters as much as how much plastic we produce, with implications for future policy.
Recycling of Plastics as a Strategy to Reduce Life Cycle GHG Emission, Microplastics and Resource Depletion
This study quantified the environmental benefits of recycling widely consumed plastic polymers, demonstrating that increased plastic recycling significantly reduces life cycle greenhouse gas emissions, microplastic pollution, and resource depletion.
A hybrid machine learning-mathematical programming optimization approach for municipal solid waste management during the pandemic
Researchers combined machine learning forecasting with mathematical supply-chain optimization to model municipal solid waste management in New York City under COVID-19 conditions, revealing trade-offs between economic efficiency and landfill diversion that could inform planning for future pandemic scenarios.
Green Supply Chain Coordination with Considering Carbon Emissions and Product Green Level Dependent Demand
Researchers developed a green supply chain coordination model that incorporates carbon emission costs and product green-level dependent demand, finding that green development policies and cost-sharing mechanisms can incentivize enterprises to adopt more sustainable supply chain operations.
Optimization of solid waste collection using RSM approach, and strategies delivering sustainable development goals (SDG’s) in Jeddah, Saudi Arabia
Researchers used statistical optimization software to improve solid waste collection efficiency in Jeddah, Saudi Arabia, where the country generates over 15 million tonnes of municipal waste annually. The study identifies cost-reducing strategies and highlights the urgent need for a resilient, modern waste management system aligned with Saudi Arabia's Vision 2030 sustainability goals.
Life cycle assessment based optimization of scenarios of reusable glass bottles using context-specific key parameters
Researchers analyzed the environmental trade-offs of switching from single-use to reusable glass bottles, finding that reusable systems can cut both carbon emissions and microplastic pollution, but only when designed with context-specific factors like local energy sources and trip distances in mind.
Integrated Recycling and The Impact of Plastic Waste from Industry and Agriculture on The Environment
This review examined the environmental impacts of plastic waste from industrial and agricultural sources and assessed integrated recycling strategies for reducing those impacts. The paper discussed how plastic waste prevention, collection, and recycling can minimize pollution and climate contributions from the growing global plastic waste stream.
