Transcript of Conservation and waste minimisation

  • 1.Conservation and Waste Reduction

2. Conservation: is an ethic of resource use, allocation, and protection. Its primary focus is upon maintaining the health of the natural world: its, fisheries, habitats, and biological diversity. Secondary focus is on materials conservation and energy conservation, which are seen as important to protect the natural world. Those who follow the conservation ethic and, especially, those who advocate or work toward conservation goals are termed conservationists.
3. Waste minimisation: is the process and the policy of reducing the amount of waste produced by a person or a society.
4. Incineration
5. Positives: Energy reclamation Reduction in volume of waste Long-term security of waste handling
6. Negatives: Large amount of air pollution and ash generated Generation of hazardous residues Large impact on surrounding communities that must deal with unpleasant side effects Loss of potential recyclables Large investment required and long lead time before operation
7. Recycling
8. Positives:You can get money for what you recycle (aluminum just about everywhere, and places that have CRV tax you get it back, sometimes up to $.10 a bottle, etc) You reduce the amount of resources needed to make the same item compared to making it without recycling It saves natural resources as it takes less energy to make something with recycled material rather something new It saves space in landfills. The items that we recycle are not biodegradable.
9. Negatives: Causes people to buy more waste because they feel good for recycling. For example, plastic bags in supermarkets and such. Its inconvenient (you have to wash all the products that had sticky substances in them (coke can)In some areas you have to pay to have your items recycled at home and its illegal not to recycle and its a hassle to drive to the nearest recycling plant and it costs gas + the plastic bags you need to store the recycled items in.
10. Landfills

  • Negatives:

11. The cost of lining systems, leachate collection, leachate treatment, covering and capping is prohibitive 12. Costs tend to drive the building of regional mega-landfills which excite intense opposition from host communities 13. Release high concentrations of methane and water pollution 14. Unpleasant odours and visual impacts affect surrounding communities Positives:

  • Can hold large amounts of waste in inert condition

15. Cheap and fast
