Hazardous waste management incorporates collection, separation, treatment, recycling and disposal of hazardous wastes. In this paper, a new multi-objective mixed integer model is presented for hazardous waste collection problem. The model aims to minimize transportation and construction costs, and environmental and population risks in hazardous waste management systems. This model is applied in...

The ZeroWIN project has identified four key strategies for the realization of zero waste in industrial networks: industrial symbiosis, supply chain management (including collaboration of actors along the supply chain), product stewardship and eco-design. A review of the current European policies has shown that “industrial symbiosis” is the ZeroWIN strategy least addressed by European Union (EU)...

The background and development of the new production philosophy are presented. The conceptual basis of the traditional and the new production philosophies, as applied in manufacturing, are examined. The traditional conceptual basis of construction is criticized, and an initial new interpretation of construction is given based on the new philosophy. Finally, the challenges of implementing the ne...

There are more than half million tons of serpentine waste produced per year during mining operation in Taiwan. This study is to develop a process to manufacture fire-resistant geopolymer based on serpentine waste. The experiment results show that the waste serpentine-based geopolymer have very good physical/mechanical characteristics. For fire resistance tests, a 10 mm thick geopolymer panel wa...

Plastics are low molecular weight organic materials, that are non degradable in the natural environment. Generation of plastic waste constitutes a major part of Municipal Solid Waste. This creates a lot of environment pollution, which in turn affects ecosystem and human health. The solution to tackle this dreadful situation lies in following 3R namely Reduce, Reuse and Recycle. Waste plastics c...

In this paper, we present the ZenRobotics Recycler, a system that sorts construction and demolition (CND) waste by picking valuable objects from a conveyor belt using robotic hands. It is the first CND recycling system that reaches a useful purity of wood, stone, and metal without resorting to human sorters. We describe how we applied machine learning to solve some of the key problems such as r...

A key challenge over the next decade for some national programmes and an important learning opportunity for many others will be the construction and operation of the first deep geological repositories for High Level Waste (HLW) and Spent Fuel (SF). As the orientation of work on disposal shifts from mainly research, development and demonstration to industrial implementation, waste management age...

Introduction: Countries around the world are looking for an appropriate, stable, and affordable replacement for the natural energies. Therefore, the waste is considered as an available resource to produce energy, which by controlling, its effects on the environment could be minimized. Materials and Methods: To conduct this review article, the scientific data related to the topic were gathered ...
