Although informal waste collectors are sometimes organized in cooperatives, their working conditions remain extremely precarious and unsafe. The paper discusses the findings of action oriented, participatory qualitative research with several recycling groups in the metropolitan region of São Paulo, Brazil. During workshops with the recyclers mapping, acting, and drawing methods helped reveal he...
Over 380000 tons of vegetable waste is produced annually in the “Campo de Dalías” zone (Almería, Spain), deriving from the diverse existing crops grown under plastic cover). Landfills containing this vegetable waste are a potential breeding ground for diseases and pests, they can also be the subject of uncontrolled burning, cause a riverbed blockage and, at the same time, they are an unsightly ...
In the fall of 1976 Congress enacted the Resource Conservation and Recovery Act, commonly referred to as RCRA. The objective of the statute is to create an orderly system for the generation, handling and disposal of hazardous waste by means of a comprehensive tracking and record keeping mechanism. RCRA does not regulate directly by statute so much as it delegates rule making authority to the U....
Increasing the production of hazardous waste during the past few years and stricter legislation in the area of permanent disposal and transportation costs were significantly elevated above activities. This creates a new, highly lucrative gray market which opens the way for the criminalization. Of great importance is the identification of illegal trafficking of hazardous waste since it can have ...
