Compost is an important Organic product of Organic Chemical Industries. Compost can be prepared in industries and also in homes. Compost prepared in chemical industries is known as industrial compost. Here we will also discuss the industrial manufacturing of compost.
What is Compost:
Compost is made up of the decomposition of organic materials like leaves, shredded twigs, kitchen waste materials, dead animals, etc. It is known as black gold for farmers. It is also used in gardens. By adding compost plant growth and health increase.
Compost is a very important organic product of chemical industries used to synthesize organic food. Compost plays a key role to synthesize USSD organic food that full fill the health standards. So, organic industries producing compost had grown economically as organic food has high requirements and high prices. As we know topsoil where microorganisms and plants exist composed of inorganic material(air, water, minerals)
and organic materials(hums) these materials provide bio elements to living things.
With increasing the human population cultivation of crops has also increased causing deficiency in soil ingredients/materials. To overcome this issue chemical industries have played a vital role. It provides inorganic fertilizers and also organic compost to full fill the deficiency of ingredients in soil. But these days requirements for organic food are high. Everybody wants organic food grown by using organic compost; because it is full of nutrients obtained from organic sources and it also provides assistance to the soil to enhance its fertility. On the other hand, inorganic fertilizers can increase the yield of crops but they damage the natural fertility of soil and food using inorganic fertilizers also causes health problems.
- Adding compost to clay soils makes it easy work for farmers.
- In sandy soils compost increases the holding capacity of the soil.
- composting is also a way of recycling leaves, dead animals, toiletries wastes, kitchen wastes, shredded twigs, etc.
Industrial compost Synthesis:
It involves the following steps;
Step no.1
Raw materials for compost are collected from curbside bins from homes, restaurants, parks, etc.
Step no.2
In step two contaminations are removed for further processing.
Step no.3
some food wastes and nitrogen-rich materials and nitrogen-rich sludge are mixed into a machine.
Step no.4
carbon-rich items, for example, leaves, branches, paper, etc. are mixed with sludge to get proper carbon to nitrogen ration
Step no.5
In this step carbon and nitrogen organics obtained from the above steps are converted into the final compost products. Chemical Industries follow three methods to obtain the compost, these are;
- Windrow Composting: In this method, the organic material is arranged in long rows called windrows. These windrow piles are aerated by turning piles manually or mechanically. It provides optimal air, heat, and moisture to get the final compost. These rows are usually4-8 feet tall and 14-16 feet wide. This size is enough to generate enough heat and temperature for chemical reactions.
- Static Pile Composting: In this method, organic wastes are mixed in a large pile. To aerate the piles' layers of loosely plied bulking agents(wood chips, shredded newspaper)are adjusted in such a way to pass air from the bottom top. These piles can also be placed on pipes that could provide or take away air from piles. In this method, compost is prepared in 3-6 months.
- In-Vessel Composting: In this method, organic wastes are placed into drums, silos, and concrete-lined trench. In this method, a large volume of organic waste is processed without taking much space as in the windrow method. It provides good control of conditions like temperature, air, moisture, airflow, etc. The mixture is mechanically turned for aeration. The size and capacity are variable. This way compost is prepared in just a few weeks, but also requires more weeks or months for ready to use Step no.6: In this step dark soil compost-enriched in nutrients obtained from the above steps after 3-6 months is packed and sold to farmers or individuals for gardening and landscaping.
