WASTE GENERATION AND MANAGEMENT Waste Materials  Classification of Waste 1. Solid Waste 2. Liquid Waste 3. Gaseous Waste Solid Waste  Solid Waste Solid waste- all discarded household, commercial waste, non-hazardous institutional and industrial waste, street sweepings, construction debris, agricultural waste and other non- hazardous/ non-toxic solid wastes.  Solid Waste It cause land pollution Toxic solid wastes affects plant growth Serve as breeding place for disease-carrying animals  Solid Waste Cause aesthetic degradation of the environment Lowers the quality of the land  Solid Waste (Management) 1. Reduce- means limiting the amount of generation of waste.  Solid Waste (Management) 2. Reuse- refers to the recovery of materials with the intention of using it either in the same or for a different purpose, without changing its physical or chemical properties.  Solid Waste (Management) 3. Recycle- means covering any used material or waste material into a new product that is useful.  Solid Waste (Management) Phases of Recycling 3.1 Segregation- the practice of separating solid waste at the point of origin. 3.2 Collection- the removal of solid waste from the source.  Solid Waste (Management) 3.3 Production of new product- the original product loses identity and may be used as raw material for the production of other goods or services.  Solid Waste (Management) 4. Composting- refers to the controlled decomposition of organic matter by microorganisms into a humus-like product.  Solid Waste (Management) 5. Landfill- refers to a waste disposal site, designed, constructed, operated, and maintained so that the potential environmental impact of the operation in the facility is controlled.  Solid Waste (Management) 6. Incineration- is the combustion of waste in the presence of oxygen, converting it into carbon dioxide, water vapor, and ash.  Solid Waste (Management) RA 9003, also known as the Ecological Solid Waste Management Act of 2000.  Solid Waste (Management) - It provides systematic, comprehensive, and ecological solid waste management policies that ensure the protection of human health and the environment and maximizes the utilization of valuable resources among others.  Solid Waste (Management) - is the integration of ecological solid waste management and resource conservation and recovery topics into the academic curricula of formal and nonformal education in order to promote environmental awareness and action among the citizenry.  Solid Waste (Management) RA 9512 also known as the National Environmental Awareness and Education Act of 2008. - the act promotes environmental awareness through environmental education.  Solid Waste (Management) - It mandates the integration of environmental education in the school curricula at all levels- public, private, formal non-formal, technical- vocational, professional, indigenous learning, and out-of-school youth courses or programs.  Liquid Waste Liquid Waste Liquid Waste Liquid Waste Liquid Waste Liquid Waste  Liquid Waste Liquid Waste- are wastes that originate from industrial, commercial, mining, and agricultural operations and from community and household activities  Liquid Waste a. Agricultural waste b. Domestic wastes c. Industrial wastewater d. Sewage  Liquid Waste Cause water pollution Affects fishes Harmful to aquatic life Sickness or death  Liquid Waste Gastroenteritis Dysentery Diarrhea Cholera  Liquid Waste (Management) RA 9275 known as Clean Waste Act of 2004 - it is the policy that aims to protect, preserve, and revive the Philippines freshwater, brackish water, and marine waters. Gaseous Waste Gaseous Waste  Gaseous Waste Gaseous Waste- is a waste product in gas form resulting from various human activities, such as manufacturing, processing, material consumption or biological processes.  Gaseous Waste 1. Carbon dioxide - produced by the burning of fossil fuels. 2. Nitrogen oxides - are usually produced from the burning of automobile and power plant fuels.  Gaseous Waste 3. Hydrocarbons- come from transportation vehicles. 4. Carbon monoxide - comes from internal combustion engines.  Gaseous Waste 5. Sulfur dioxide - is produced by the burning of coal. 6. Hydrogen sulfide - comes from geothermal power plants.  Gaseous Waste 7. Methane - is produced by the anaerobic decomposition of organic matter.  Gaseous Waste Some gaseous are wastes called Greenhouse gases. - It include carbon dioxide, methane, nitrous oxide, water vapor, and chlorofluorocarbon.  Gaseous Waste - Nitrogen and sulfur oxides, along with water, form acid rain. - Acid corrodes cement and metals  Gaseous Waste Acid rain lower the pH of rivers and affect aquatic life. It also reduces forest and crop productivity. Hydrogen sulfide, nitrogen, and sulfur oxides may cause respiratory ailments.  Gaseous Waste (Management) RA 8749, also known as Clean Air Act of 1999. - governs the management of gaseous wastes. - it provides a framework for sustainable development by balancing development and environmental protection.  Gaseous Waste (Management) - its primary focus is the prevention of pollution rather than its control, and the promotion of a system of accountability for the citizenry for increased compliance.
