The production of activated carbons (ACs) from dirty plastic wastes derived the mechanical/biological treatment urban solid wastes, disposable plastics and used in agriculture is reported. use these precursors innovative contributes to circular economy by valorization that are usually disposed landfills. ACs were produced physical activation, with air or CO2, chemical KOH K2CO3. presented a BET...

We consider a cost allocation problem arising from a consortium for urban solid waste collection and disposal. A classical allocation rule is the proportional division according to the volume of waste collected. For example in Italy this is the proposal of the so-called " Decreto Ronchi " (a collection of laws that rule this topic). We propose a different allocation method rooted in game theory...

This paper analyses the interest which developed in Great Britain around composting from the late 1920s. It argues that before the current vogue for composting, the technique attracted considerable attention in the middle of the twentieth century and that interest in this technology was not limited to a few 'mystical' members of the organic movement. This paper also analyses the role of an inst...

Municipal solid waste (MSW) management has emerged as an important human and environmental health issue. A large number of poor, downtrodden marginalized urban women are thriving on these recyclable wastes and are potentially exposed to a variety of occupational biohazards and safety risks. At present there are about millions of women in India who scavenge the city’s garbage bins and MSW dispos...

Waste treatment facilities are often shared among different municipalities as a means of managing wastes more efficiently. Usually, management costs are assigned to each municipality depending on the size of the population or total amount of waste produced, regardless of important environmental aspects such as per capita waste generation or achievements in composting or recycling. This paper pr...

The operating conditions in spouted bed regime of uniform beds consisting of different biomass wastes dry and wet have been studied to determine the applicability of conical spouted beds with a draft tube in the drying of biomass wastes. This experimental study has been carried out at room temperature and the effect of the solid humidity on the stability of beds of biomass wastes has been deter...

In several countries, low-level radioactive wastes are treated and stored awaiting construction and operation of a final repository. In some cases, interim storage may be extended for decades requiring special attention regarding security issues. The International Atomic Energy Agency (IAEA) recommends segregation of wastes that may be exempted from interim storage or ultimate disposal. The pap...

Objective: Dental solid wastes often contain hazardous substances. The first step of management of dental solid wastes includes detection and classification of these substances. This study aimed to qualitatively and quantitatively assess the management of solid wastes by dental offices in Urmia city in 2013. Methods: This descriptive study was conducted on all private dental offices in Urmia...

As populations and economies expand, increasing quantities of natural resources are extracted and processed, more goods are moved, more people travel, more energy is used, and more wastes are generated. One outcome is over 800 million motor vehicles operating in the world today, consuming around 40 million barrels per day of petroleum, producing about half the urban pollution, and emitting over...
