Two very recognizable symbols are the ones for recycling and composting. But what is the difference between the 2 processes? The composting process refers only to what can be "composted" which is the bio-degradation of organic matter, such as yard waste and food. This process, usually done by a garden composter is performed by micro-organisms, mostly bacteria, but also yeasts and fungi. There are many contributors to the different phases of decomposition including earthworms and fruit flies. Composting is usually not considered as recycling.
Recycling involves processing used materials into new products to prevent waste, reduce pollution (both air and water) and to reduce the need for conventional waste disposal. Recyclable materials include glass, paper, metal, textiles and electronics. For the processing of some materials either garden composters or recycling bins are used. The materials are either brought to a collection center or picked up curbside and sorted and reprocessed into new materials.
How does Leonardo DiCaprio figure into all of this? He has been an avid supporter of the "green movement" and the environment for many years and practices what he preaches. He recently moved into a $9M environmentally correct apartment in New York City. His apartment has rotating solar panels that provide 10% of his power. Leonardo says that he lives in the "green manner" and has released a feature length documentary "11th Hour" which focuses on the problems facing the planet's life systems. This film was done with the help of over 50 of the most prominent thinkers and activists including Mikhail Gorbachev and physicist Stephen Hawking. Global warming, deforestation, species extinction and depletion of ocean habitats are addressed. The feature offers hope and solutions. The "11th Hour" calls for a healthier future and this includes recycling and composting.
