  1. 1. Recycling- Compost<br />Zespół Szkół z <br />Oddziałami <br />Integracyjnymi<br /> im. J. Korczaka<br />w Smólniku<br />Poland<br />
  2. 2. Recycling<br />Recycling - one of comprehensive methods of environmental protection. Its aim is to reduce consumption of natural resources and reduce waste.<br />
  3. 3. Composting<br />Composting (organic recycling) - a natural method of disposal and waste management, involving the decomposition of organic matter by micro-organisms - aerobic bacteria, nematodes, etc.. It is the processing of the substance under controlled conditions in the presence of oxygen (air) at a suitable temperature and humidity.<br />
  4. 4. Purpose of composting<br />The purpose of building a system of composting is to provide a healthy and nutrient-rich living environment for bacteria. The fastest composting occurs when the ratio of carbon to nitrogen in the environment is 25:1 - 30:1. For example, cut grass, this is a ratio of 19:1 and autumn leaves - 55:1. Mixing these two ingredients in equal proportions gives a ratio of nutrients. In industrial composting observe this relationship quite closely, in the case of household composting is too complicated and easier to apply more recipes.<br />
  5. 5. Types of composting<br />Backyard composting — If you have a yard and a balance of browns (fallen leaves or straw) and greens (grass clippings and food scraps), you have all you need to make compost. <br />Worm composting (vermicomposting) — If you have a tiny yard or live in an apartment or have an abundance of food scraps, this type of composting is for you. <br />
  6. 6. GrasscyclingIf you have grass clippings <br />and don't want to use them in a<br /> compost pile you can leave them on <br />the lawn to decompose. <br />
  7. 7. 10 good reasons why you <br />should compost: <br />Yard and food waste make up 30% of the waste stream. Composting your kitchen and yard trimmings helps divert that waste from the landfill, waterways and water treatment facilities. <br />You will significantly reduce pest problems–and your use of pesticides. <br />Healthy plants from healthy soil look better, produce better and have a much greater ability to fight off pests and diseases. <br />Adding organic materials to the soil improves moisture retention. <br />
  8. 8. Adding decomposed organic material to the soil feeds beneficial organisms. <br />Compost amends both sandy and clay soils. <br />Compost provides a balanced, slow–release source of nutrients that helps the soil hold nutrients long enough for plants to use them. <br />
  9. 9. Composting saves money–you avoid the cost of buying soil conditioners, baggedmanure etc. <br />Feeding your plants well will improve your own diet. Plants grown in depleted soils have a reduced nutrient content. <br />Home composting is a valuable tool in educating children about nature and the cycle of life. <br />
  10. 10. Backyard Composting<br />Basics<br />Nature has been composting since the beginning of the earth. All organic matter eventually breaks down. Composting in your backyard uses the same principles that nature uses - we just try to speed it up by creating an environment that supports microbial activity. The elements<br /> necessary <br />to promote this environment are: <br />- Air - Moisture - Organic matter - Carbon to nitrogen ratio - Temperature - Volume<br />
