What You Need to Know About Waste Management

Organic fertilizer

Organic composts are manure derived from animal matter, animal excreta (compost) human excreta & vegetable matter (e.g. manure & crop residues).Naturally occurring organic fertilizers include animal wastes from meat processing, peat, compost, slurry & guano. In contrast the majority of fertilizers used in commercial farming is extracted from minerals (e.g phosphate rock) or produced industrially (e.g ammonia). Organic farming a system of farming allows for certain composts & amendments & disallows others that are also distinct from this topic.

Mineral

By various definitions minerals are separate from organic materials. However certain organic fertilizers & amendments are mined specifically guano & peat. Other mined minerals are fossil products of animal activity such as greensand (anaerobic marine deposits) some lime-stones (fossil shell deposits) and some rock phosphates (fossil guano). Peat a precursor to coal presents no nutritional value to the plants but improves the soil by aeration & absorbing water. It is sometimes credited as being the mainly widely use organic fertilizer & by volume is the top organic amendment.

Animal sources

Animal sourced materials include both animal manures & residues from the slaughter of animals. Compost Machine are derived from milk-producing dairy animals, egg-producing poultry & animals raised for meat & hide production. When any animal is butchered only about 40% to 60% of the live animal is converted to market product with the remaining 40% to 60% classed as by-products. These by-products of animal slaughter, mostly inedible -- blood, bone, feathers, hides, hoofs, horns, -- can be refined into agricultural fertilizers including blood meal, bone meal fish meal & feather meal. Chicken litter which consists of chicken compost mixed with sawdust is an organic fertilizer that has been proposed to be superior for conditioning soil for harvest than synthetic fertilizers.

Plant

Processed organic fertilizers include compost humic acid, amino acids & seaweed extracts. Other examples are natural enzyme-digested proteins. Decomposing crop residue (green compost) from prior years is another source of fertility. Other ARS studies have found that algae used to capture nitrogen and phosphorus runoff from farming fields can not only prevent water contamination of these nutrients, Compost Machine Manufacturers also can be used as organic manure. ARS scientists originally developed the "algal turf scrubber" to reduce nutrient runoff & increase class of water flowing into streams, rivers & lakes. They found that these nutrient rich algae once dried can be useful to cucumber & corn seedlings & result in development comparable to that seen using synthetic fertilizers.The waste hierarchy refers to the 3 Rs reduce, reuse & recycle which classifies waste management strategies according to their desirability in terms of waste minimization. The waste hierarchy is the cornerstone of mainly waste minimization strategies. The aim of the waste hierarchy is to extract the most practical benefits from products & to generate the minimum amount of end waste; see: resource recovery.[6] The waste hierarchy is represented as a pyramid because the basic is that policies should promote measures to prevent the generation of waste. The next step or preferred action is to seek choice uses for the waste that has been generated i.e. by re-use. The next is recycling which includes composting. Following this step is material recovery & waste-to-energy. The final achievement is disposal in land-fills or through incineration without energy recovery. This last step is the final resort for waste which has not been prevented diverted or recovered. The waste hierarchy represents the progression of a manufactured goods or material through the sequential stages of the pyramid of waste management. The hierarchy represents the latter parts of the life cycle for every product.

Life-cycle of a product

The life-cycle begins with design then proceeds through manufacture, distribution & primary use & then follows through the waste hierarchy's stages of reduce, reuse & recycle. Each stage in the life-cycle offers opportunities for policy intervention to rethink require for the product to redesign minimizing waste potential to extend its use. Product life cycle analysis is a life to optimize the use of the world's limited resources by avoiding the unnecessary generation of waste.
