The efficient large-scale recycling of plastic waste is of increasing interest from an ecological and economic point of view but it represents a goal that has yet to be achieved by the recycling industry. European project W2Plastics (FP7) aims at a fundamental change of the present status of plastics recycling by applying the Magnetic Density Separation (MDS) technology as well as the Ultrasoun...

Nowadays rules of environmental protection strictly regulate pollution material emission into environment. To keep the environmental protection laws recycling is one of the useful methods of waste material treatment. We have developed a new method for the treatment of industrial waste water and named it boundary layer separation method (BLSM). We apply the phenomena that ions can be enriched in...

Biofiltration is one of the air pollution control technologies that utilizes the microorganisms to biologically degrade Volatile Organic Compounds (VOCs) and odor contained in waste air streams. The microorganism exists on the surface and in a thin water film surrounding the surface of biofilter material and degrades the pollutants present in the fluid. This method is distinguished from other b...

Waste separation and recycling programs in higher education institutions requires an approach that reach people in different ways. Social marketing approach has proved to be effective in helping reach the desired change for very different initiatives. In this paper is presented a sixteen month experience of a paper and cardboard separation program at the Ensenada Campus of the Autonomous Univer...

Separation of plastic from various types of waste streams represents one of major problematic process in energy recovery through different thermochemical processes. The sorting of plastics is a very essential step in different waste management technique. Manual sorting is suitable when plastic component are present in large amount but it is a labor intensive process. In automated sorting techni...

This paper describes the context, the basic assumptions and the main findings of a joint research project aimed at identifying the optimal breakdown between material recovery and energy recovery from municipal solid waste (MSW) in the framework of integrated waste management systems (IWMS). The project was carried out from 2007 to 2009 by five research groups at Politecnico di Milano, the Unive...

processing and recovery is a key functional element in municipal solid waste management system (mswms). reuse, recycle and recovery of valuable components of waste stream are given much attention in mswms in both developed and developing countries. the main concern of municipalities is the sound management of recyclable materials. source separation as a best practice for management of trash and...

A critical assumption of studies assessing comparatively waste management options concerns the constant average cost for selective collection regardless the source separation level (SSL) reached, and the neglect of the mass constraint. The present study compares alternative waste management scenarios through the development of a desktop model that tries to remove the above assumption. Several a...
