Introduction to Waste Management Flashcards
unwanted or useless materials
Waste
any of the many unwanted substances or toxins that are expelled from living organisms, metabolic waste; such as urea and sweat.
waste
“substances or objects which are disposed of or are intended to be disposed of or are required to be disposed of by the provisions of the law”
Basel Convention Definition of Wastes
“any operation which may lead to resource recovery, recycling, reclamation, direct re-use or alternative uses (Annex IVB of the Basel convention)”
Disposal
an international treaty that was designed to reduce the movements of hazardous waste between nations, specially to prevent transfer of hazardous waste from developed to less developed countries (LDCs)
Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and Their Disposal, usually known simply as Basel Convention
The convention is also intended to minimize the amount and toxicity of wastes generated, to ensure their environmentally sound management as closely as possible to the source of generation, and to assist LDCs in environmentally sound management of the hazardous and other wastes they generate.
Basel Convention
The Basel Convention was opened for signature on __________
March 22, 1989
The Basel Convention entered into force on __________
May 5, 1992
“Wastes are materials that are not prime products (that is products produced for the market) for which the generator has no further use in terms of his/her own purposes of production, transformation or consumption, and of which he/she wants to dispose. Wastes may be generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, and other human activities. Residuals recycled or reused at the place of generation are excluded.”
Produced by the United Nations Statistics Division (U.N.S.D.)
These are materials that are not prime products (that is products produced for the market) for which the generator has no further use in terms of his/her own purposes of production, transformation or consumption, and of which he/she wants to dispose.
Waste
These may be generated during the extraction of raw materials, the processing of raw materials into intermediate and final products, the consumption of final products, and other human activities. Residuals recycled or reused at the place of generation are excluded.
Waste
wastes in solid forms, domestic, commercial and
industrial wastes
Solid Wastes
plastics, styrofoam containers, bottles, cans, papers, scrap iron, and other trash
Solid Wastes
wastes in liquid form
Liquid wastes
domestic washings, chemicals, oils, waste water from ponds, manufacturing industries and other source
Liquid wastes
Any garbage or refuse according to EPA regulations
Municipal Solid Waste
Sludge from a wastewater treatment plant, water supply treatment plant, or air pollution control facility
solid waste
Solid, liquid, semi-solid, or contained gaseous material from industrial, commercial, mining, and agricultural operations, and from community activities
solid waste
Classification of Wastes according to properties.
They can be degraded (paper, wood, fruits and others)
Biodegradable
Classification of Wastes according to properties.
They cannot be degraded (plastics, bottles, old machines,cans, styrofoam containers and others)
Nonbiodegradable
Classification of Wastes according to their Effects on Human Health and the Environment.
Substances unsafe to use commercially, industrially, agriculturally, or economically and have any of the following properties- ignitability, corrosivity, reactivity & toxicity.
Hazardous wastes
Substances safe to use commercially, industrially, agriculturally, or economically and do not have any of those properties mentioned above. These substances usually create disposal problems.
Non-hazardous
Classification of wastes according to their
origin and type.
Solid wastes that include household garbage, rubbish, construction & demolition debris, sanitation residues, packaging materials, trade refuges etc. are managed by any municipality.
Municipal Solid wastes
Classification of wastes according to their
origin and type.
Solid or liquid wastes including containers, intermediate or end products
generated during diagnosis, treatment & research activities of medical sciences.
Bio-medical wastes
