The pros and cons are intermingled because what might be a pro to one person is a con to someone else. Digestion can be either aerobic or anaerobic, but is more often configured as an anaerobic process for the purpose of producing and capturing methane-rich biogas (aerobic digestion is used in some sewage sludge treatment schemes for stabilization and pasteurization, but is very energy-intensive). Composting is a biological process in which both aerobic and anaerobic microorganisms decompose the organic matter. Experts vary in their opinions of the proper balance between browns and … Every hot compost pile needs some materials high in nitrogen (called “green materials”) and some materials high in carbon (called “brown materials”). Advantages and disadvantages of composting methods. When raw organic materials like crop residues, animal wastes, food wastes, some municipal wastes and suitable industrial wastes having undergone composting, can make them become more suitable to apply to the soil as a fertilizing resource.

Composting is one of the waste management options available to us, along with other common options like landfill, recycling and incineration. The advantages of in-vessel composting are tighter control of temperature, odors, rodent control and the ability to compost meat and dairy products. And over-feeding the worms can kill them and cause the bin to stink. Can Take Work & Time To Develop Good Humus/Fertilizer – Developing a good compost soil nutrient mix can take work and time (right balance of nitrogen and other nutrients, and manual turning and stirring of the mix) – and if you aren’t putting the right balances of organic matter into the compost, the end compost ‘humus’ can actually be damaging or have a neutral effect on the soil you spread it on. (Best Waste Management Options). Composting also has limitations in that only certain materials can be composted. The anaerobic process, which is essentially putrefaction (sorr… Another main disadvantage is the labor in digging a trench. There are a many good reasons for getting into the habit of NOT tossing your organic waste into the trash. Disadvantages of Composting. This also applies if the composting is done under aerobic conditions, Available On Several Scales & Levels – Composting can be done at the commercial and industrial levels, but also on a household level – it’s available to everyone to do, Keeps Organic Matter Out Of Landfills – Composting means that organic matter like food waste and yard trimmings stays out of landfills where it might decompose anaerobically – a major cause of methane greenhouse gas emissions. The resulting compost is dried to produce a bio-fertiliser. Composting is an aerobic process, so oxygen is essential for its success.

Also sizeable amount of sludge is produced in aerobic method. Well-composted sludge can meet the requirements for class A biosolids and can be sold to distributors and the public. Disadvantages of Anaerobic Composting Putrification of organic materials can lead to very unpleasant odors, due to release of sulfur-containing compounds such as hydrogen sulfide Process requires a lot more time to produce usable compost compared to aerobic composting Aerobic process, also called Composting, is a natural process that rot or decompose organic matter by microorganisms under some controlled conditions. It is suitable for a relatively homogenous mix of organic waste and work well for larger quantity generators of yard trimmings and compostable municipal solid waste (e.g., food scraps, paper products), such as local governments, landscapers, or farms. A major disadvantage of trench composting is that it’s a slow process. In my case of using compost bins, the obvious disadvantages are having an out of ground system that is a little unsightly in the garden. Aerobic digestion, or composting, is a commonly used treatment method for BW of different origins or a mixture of such wastes. In addition, temperature, moisture content and aeration must be carefully monitored during decomposition to eliminate pathogens and completely convert the organic waste into compost. The theory of automated composting system further reduces investment and operating costs in engineering applications and achieves good engineering results. With roughly 27% of landfill waste (in some countries) being made up of organic matter – it’s interesting to think how much waste could potentially be kept out of landfills if we composted more often, Can Produce A Natural Fertilizer – Composting can produce a type of fertilizer or nutrient rich ‘humus’ mix which can be used for growing plants and food, and generally to enrich or even restore some types of damaged soils, Can Help Decrease The Use Of Synthetic Fertilizer – Composting can decrease the use of synthetic fertilizers (which has it’s own environmental issues it causes), Can Help With Soil Health – Compost that improves soil health (through improved soil water retention for example) can also indirectly save water and other natural resources – it encourages resource sustainability. The brown materials add bulk and air flow, preventing anaerobic decay from taking over and creating a foul smell. In-vessel reactors have limited flexibility to handle changing conditions and are maintenance intensive. tonnes of compost, and about 72 MW of electricity from biogas [2]. they are penalised for doing the right thing, Potential Contamination Issues – Compost can be contaminated if the wrong waste is put in there – which spoils the whole compost mix.
