Learn to Manage Waste -household, commercial, garden, etc what is waste and how can be minimized what is pollution how to dispose of waste naturally harness natural processes to better manage waste disposal. Lesson Structure There are 6 lessons in this course: Domestic Waste Definitions The Earths environment Conservation and use of resources Value of resources: economic, ecological and aesthetic Damage being caused Urbanisation The impact of humans Sewage and it's treatment Characteristics of sewage Components of sewage - solids, organic material, industrial waste Decomposition of sewage The nitrogen cycle Classification of sewage systems Storm water systems and management Dry rubbish Nature of refuse Placement and protection of bins Trade waste Refuse collection systems Refuse collection vehicles Salvage materials Safe disposal of household chemicals Street Cleaning & Disposal Of Refuse Types of street refuse Methods of street cleaning - gritting, sanding, sweeping, washing, etc Cleaning storm water pits Managing snow Refuse disposal-separation, controlled tipping, combustion, pulversisation, etc Refuse for fertiliser Methods of refuse Sorting - screening, magnetic, hand sorting Types of incinerators Vacuumn systems for refuse collection - garchey system, gandillon Harvesting energy from combustion Industrial Waste Types of industrial pollution The greenhouse effect Ozone depletion Toxic and Nuclear Waste Nuclear power Nuclear fission Mining nuclear fuel Uranium enrichment Gas diffusion Gas centrifuge Nuclear waste Transporting nuclear waste Reprocessing Health risks of nuclear waste Water Quality and Treatment Industrial effluent Pricing control compared with direct control Types of water impurities Scope of purification Managing water for public supply Water treatment methods Purification methods - sedimentation, filtration, disinfection, aeration, screening, etc Recycling sewage water Recycling waste water Reed bed treatment Improving water quality from any source - physical, chemical, biological impurities Water borne diseases Recycling Waste Scope and nature of recycling Rubbish tips (dumps) Recycling plastics Recycling metals Recycling glass Recycling paper Recycling rubber Actions by individuals (at home or work) - reducing, reusing and recycling waste Consider both the Quantity and Quality of Waste Even waste that is able to decompose safely, and is not toxic to humans, can still be a problem if it occurs in excessively high quantities. Too much of a good thing can become a bad thing! Education of the general population is an important way of protecting the environment from the negative impacts of both safe waste, and more dangerous waste. Where potentially dangerous chemicals are required in a household only the minimum amount should be kept. They need to be stored and disposed of in a safe manner. Dangerous household chemicals should not be disposed in the garbage, burned, buried, or poured down the sewer without processing. Storage, usage and disposal of dangerous chemicals can be regulated by various authorities, be they local, national or international. Disposal and processing of dangerous wastes is conducted by special organisations. Processing of dangerous waste can start with mechanical conversion of waste form one form to another (e.g. disassembling spray cans or mercury lamps). The aim of processing is to convert dangerous waste into non-dangerous material that can be safely disposed using one of four methods depending on the laws and regulations in your area: Sewer; Landfill; Recycling centre; Combustion.
