  3. 3. What are 3 R’s of Environment? • The three R's – reduce, reuse and recycle – all help to cut down on the amount of waste we throw away. They conserve natural resources, landfill space and energy. Plus, the three R's save land and money communities must use to dispose of waste in landfills.
  4. 4. Reduce • "Reduce" means using fewer resources in the first place. This is the most effective of the three Rs and the place to begin. It is also the hardest because it requires letting go of some very American notions, including the bigger the better, new trumps old and convenience is next to godliness. But you don't need to let go completely or all at once. "Reduce" is a comparative word. It says: cut back from where you are now.
  5. 5. Ways to Reduce • Buy products in bulk. Larger, economy-size products or ones in concentrated form use less packaging and usually cost less per ounce. • Avoid over-packaged goods, especially ones packed with several materials such as foil, paper, and plastic. They are difficult to recycle, plus you pay more for the package. • Avoid disposable goods, such as paper plates, cups, napkins, razors, and lighters. Throwaways contribute to the problem and cost more because they must be replaced again and again. • Buy durable goods – ones that are well-built or that carry good warranties. They will last longer, save money in the long run and save landfill space. • At work, make two-sided copies when ever possible. • Maintain central files rather than using several files for individuals. • Use electronic mail or main bulletin board.
  6. 6. Reuse • Reuse is the action or practice of using an item, whether for its original purpose (conventional reuse) or to fulfil a different function (creative reuse or repurposing). It should be distinguished from recycling, which is the breaking down of used items to make raw materials for the manufacture of new products. Reuse – by taking, but not reprocessing, previously used items – helps save time, money, energy and resources. In broader economic terms, it can make quality products available to people and organizations with limited means, while generating jobs and business activity that contribute to the economy.
  7. 7. Ways to Reuse • Reuse products for the same purpose. Save paper and plastic bags, and repair broken appliances, furniture and toys. • Reuse products in different ways. Use a coffee can to pack a lunch; use plastic microwave dinner trays as picnic dishes. • Sell old clothes, appliances, toys, and furniture in garage sales or ads, or donate them to charities. • Use reseal able containers rather than plastic wrap. • Use a ceramic coffee mug instead of paper cups. • Reuse grocery bags or bring your own cloth bags to the store. Do not take a bag from the store unless you need one.
  8. 8. Recycle • Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution (from incineration) and water pollution (from landfilling).
  9. 9. Ways to Recycle • Buy products made from recycled material. Look for the recycling symbol or ask store managers or salesmen. The recycling symbol means one of two things – either the product is made of recycled material, or the item can be recycled. For instance, many plastic containers have a recycling symbol with a numbered code the identifies what type of plastic resin it is made from. However, just because the container has this code does not mean it can be easily recycled locally. • Check collection centers and curbside pickup services to see what they accept and begin collecting those materials. These can include metal cans, newspapers, paper products, glass, plastics and oil. • Consider purchasing recycled materials at work when purchasing material for office supply, office equipment or manufacturing. • Speak to store managers and ask for products and packaging that help cut down on waste, such as recycled products and products that are not over packaged. • Buy products made from material that is collected for recycling in your community. • Use recycled paper for letterhead, copier paper and newsletters.
  10. 10. Which items can be recycled? • Paper including newspapers, magazines, and mixed paper. • Cardboard (OCC) • Glass bottles and jars. • Rigid plastic products. • Metal containers, including tin, aluminum, and steel cans. • Food waste, if your city has an organics collection program.
  11. 11. Biodegradable Waste • Biodegradable waste includes any organic matter in waste which can be broken down into carbon dioxide, water, methane or simple organic molecules by micro-organisms and other living things by composting, aerobic digestion, anaerobic digestion or similar processes. In waste management, it also includes some inorganic materials which can be decomposed by bacteria. Such materials include gypsum and its products such as plasterboard and other simple organic sulfates which can decompose to yield hydrogen sulphide in anaerobic land-fill conditions.
  12. 12. Advantages of Biodegradable Waste • Biodegradable Plastics are easy to Recycle • They consume Less Energy during their Manufacture • Reduction of the Amount of Waste Produced • Lower Petroleum Consumption • Compostability • Reduction of Carbon Dioxide levels • Reduction of Emission of Greenhouse Gas Levels
  13. 13. How these 3R’s help our Environment • The three R's – reduce, reuse and recycle – all help to cut down on the amount of waste we throw away. They conserve natural resources, landfill space and energy. Plus, the three R's save land and money communities must use to dispose of waste in landfills. Siting a new landfill has become difficult and more expensive due to environmental regulations and public opposition.
