Editor's Notes
- Good morning, My name is Isabel Monreal, I’m going to present the “ENVIRONMENTAL SUSTAINABILITY OF ORGANIC WASTE” I will talk about Vermicomposting, The Big red worm program in Nebraska and Environmental sustainability benefits
- Vermicomposting is the use worms to break down the organic waste in to products rich in nutrients for gardening, also this allows reduce the cost in landfill waste.
- The Farmers Union’s Big Red Worm Program, launched in August 2015, collects food scraps from Lincoln public schools (LPS), restaurants, and pubs, and also collects animal compost from Lincoln Zoo and horse barns. Lincoln, NE’s City of Public Works and Utilities Department awarded grants to the Nebraska Farmers Union and LPS to support a program that diverts food waste from Lincoln's landfill, which is projected to reach capacity in 16 years. The project will decrease food waste landfill and reduce cost taxpayers in garbage fees. The cost cutting in landfill waste will be reduce in 16%. Also the product of vermicomposting will be turned into a commodity that benefits farmers, gardeners and others. The money and environment saving goal has been one that Lincoln has tried to find new ways to achieve.
- ENTRY Worms do not have teeth. They pull food in through their mouths into a throat structure called the pharynx. Then, strong muscles push the food down into the digestive system for storage and processing. PROCESSING Much of the hard work happens in the gizzard, where worms collect hard particles of sand, soil or wood chips that grind ingested food into digestible bits. Nutrients are absorbed. The rest passes into the intestines on its way out. Enzymes and microbes help with digestion along the way. EXCRETION Waste comes out of the anus as individual pellets, about 0.08 inches in diameter. They are soft – usually more than 60 percent moisture and initially hydrophobic (they don’t absorb water right away). Clumped together, these “castings” have the consistency of clay.
- In the work of Guo et al., presented in 2015, they found that the digestion of cattle manure by earthworms converts the wasteful cattle manure into more valuable organic fertilizer that is friendly to the environment. Some nutrients are used by earthworms, and plentiful earthworms have been obtained. The activities of earthworms made the remainder compost product contain some plant growth regulators which led to the plant to fully use the agronomic nutrients to generate greater above ground biomass and higher grain yield. Vermicomposting increased biomass by 7.7 % and maize grain yield by 18.3 %. The global output of vermicomposting was thus higher by 304 % due to higher grain yield and earthworm income
- Dajko & Vasilikiotis worked in a research about olive mill waste they found that its production presents a serious soil and water pollution threat to the environment in the Mediterranean region. Their study demonstrated that vermicomposting of olive mill waste can produce a vermicompost with no phytotoxicity allowing the recycling of this olive mill by-product into the soil and reducing the environmental impact of olive mill waste, Vermicomposting using the earthworm Eisenia fetida reduce environmental pollution and produce of a high quality organic fertilizer and soil amendment soil.
- The benefits of composting are being exploited in Lincoln, NE’s City of Public Works and Utilities Department awarded $14,750 to the Nebraska Farmers Union to support a program that diverts food waste from Lincoln's landfill, which is projected to reach capacity in 16 years. The Farmers Union’s "Big Red Worms" (BRW) "vermicomposting" program, launched in August 2015, collects food scraps from Lincoln public schools (LPS), restaurants, and pubs, and also collects animal compost from Lincoln Zoo and horse barns. The food scraps and other organic waste will be precomposted and fed to worms, which produce vermicompost castings, the end result of broken down organic matter from earthworms. Nebraska Farmers Union’s BRW program now collects over 10 tons of food waste per month, and plans to double that figure in time. The City also awarded $20,000 to LPS, which will be used to add nine schools to its organic waste composting pilot project, which currently has 13 participating schools that collect food waste and transport it to Prairieland Dairy to compost with dairy cattle manure.
- In this program have been turning a negative into a positive Save money in reduce cost taxpayers in garbage fees. The cost cutting in landfill waste will be reduce in 16%. Also the product of vermicomposting will be turned into a commodity that benefits farmers, gardeners and others. The money and environment saving goal has been one that Lincoln has tried to find new ways to achieve.
- Vermicomposting of combined industrial and municipal organic waste offers multiple benefits on the carbon footprint for industry, the community and for the agribusiness sectors. Of significance is the reduction in greenhouse gas emissions originating from the land filling of organic waste and the avoidance of the high economic penalties associated with the design, construction and ongoing monitoring of landfills. For the farming and horticulture sectors, soil carbon would be increased and higher carbon sequestration by increasing root mass and crop yields. A reduction in mineral fertilizer application would reduce the carbon footprint and a better soil structure would reduce nitrous oxide (N2O) emissions from pastoral soils.
- As we have seen vermicomposting is a great viable operation and model for: industrial, commercial and domestic organic waste management. Also vermicomposting reduce cost in landfills, it has benefits to environment, turning the waste in a useful product for gardening and crops. The city of Lincoln Nebraska Launched in August 2015 vermicomposting program, the program now collects over 10 tons of food waste per month with plans to double that amount. In the next 16 years, the Lincoln Landfill of Bluff Road is expected to be full, thanks to programs like these the life's time of landfills can be extended.
