Composting is a complex, aerobic microbiological process capable of converting the organic fraction of municipal solid waste, and many other organic wastes, into beneficial compost products. When free of contaminants, it is an excellent soil fertilizer as it increases its humus content. << /Type /Pages Aerobic Composting.

Performance of two-phase anaerobic high solid digestion 49 Table 19. These include moisture contents of around composting involve accelerated aerobic decomposition using a range of measures: chopping raw materials into small pieces; using mineral compounds such as ammonium sulphate, chicken manure, and urine; and turning the material on a daily basis. In aerobic composting, oxygen is used to accelerate the decay of organic material into compost. endobj /Pages 2 0 R /Resources 12 0 R /Parent 2 0 R << It is a process of using the proper materials and mixing them to achieve that right consistency and balance. 7 0 obj The treatment of solid waste can be carried out by various methods like sanitary landfill, composting and incineration. Organic matter is turned into compost by micro-organisms living in the composting material (biomass). It can therefore be used to recycle organic material. When the compost pile cools down, it may mean two things: (1) composting is complete or (2) anaerobic organisms have taken over your compost pile….which means you need to mix the pile to keep oxygen circulating enough to encourage aerobic microbes to start working again. Aerobic and anaerobic digestion methods have their own advantages and disadvantages. Unlike aerobic composting, the pile will not heat up. The microbes responsible for composting are naturally occurring and live in the moisture surrounding organic matter. /Type /Page << /Length 19 0 R Aerobic composting is the process by which organic wastes are converted into compost or manure in presence of air.In this process, aerobic microorganisms break down organic matter and produce carbon dioxide, ammonia, water, heat and humus, the relatively stable organic end-product. Carbon from organic compounds is used as asource of energy while nitrogen is recycled. The opposite of this, without air, is anaerobic composting. /MediaBox [0 0 595.2199707031 842] Aerobic composting is a bio-oxidative process whereby a large portion of the degradable organic carbon is converted into carbon dioxide and water in the presence of oxygen [4]. aeration) and moisture content. /Version /1.4 /CropBox [0 0 595.2199707031 842] The term „composting“ describes a natural process, in which microorganisms transform organic residues in stabilized products. 1 0 obj /Thumb 8 0 R /MediaBox [0 0 595.2199707031 842] Aerobic composting means composting with air.

There are two fundamental types of composting aerobic and anaerobic: 4.1 Aerobic Composting is the decomposition of organic wastes in the presence of oxygen (air); products from this process include CO2, NH3, water and heat. Aerobic composting is the creation of fertilizing compost that relies on bacteria that thrive in an oxygen-rich environment. Composting is the controlled aerobic biological de-composition of organic matter into a stable, humus-like product called compost. /Thumb 17 0 R /Rotate 0 Advantages of aerobic hot composting process a) … 7.2 Know the monitoring and control requirements for the aerobic composting process. Many tropical farming systems have been evolved during last few decades and If the supply of oxygen is limited, the composting process may turn anaerobic, which is a much slower and odorous process. Aerobic composting. After the thermophilic phase is com-pleted, the compost temperature drops, and it is not restored by turning If the proper amounts of food (carbon), nutrients, water and air are provided, aerobic organisms will dominate the compost pile and decompose the raw organic materials Oxygen and Aeration An aerobic composting process consumes large amounts of oxygen.
