Pretreatment equipment mainly includes metering equipment, compost fertilizer crusher, mixer, feeding equipment and screening machine. In the whole commercial composting process, the functions of these equipment are as follows: Increase the organic matter in raw materials. Provide appropriate material granularity for fermentation.
What is the difference between pre-treatment and post-treatment in composting?
The raw material processing before the start of one composting is called pre-treatment, and the raw material processing after the post-cooking stage is called post-treatment. Whether the pre-treatment or post-treatment needs to depend on the characteristics of the raw materials and the desired product quality.

Composting is a method for treating solid waste in which organic material is broken down by microorganisms in the presence of oxygen to a point where it can be safely stored, handled and applied to the environment. Composting is an essential part of reducing household wastes.

Benefits of Composting Enriches soil, helping retain moisture and suppress plant diseases and pests. Reduces the need for chemical fertilizers. Encourages the production of beneficial bacteria and fungi that break down organic matter to create humus, a rich nutrient-filled material.
What is composting in short answer?
Composting is a microbial process that converts plant materials such as grass clippings and leaves to a more usable organic soil amendment or mulch. Gardeners have used compost for centuries to increase soil organic matter, improve soil physical properties, and supply some of the essential nutrients for plant growth.
What are the 3 types of compost?
Composting means breaking down organic material. There are three kinds: aerobic, anaerobic, and vermicomposting. Each has its pros and cons. Households, farms, restaurants, schools, offices and places of business produce compostable materials.

What is a dry system?
Dry: Dehydrators and accelerated composters are dry systems. They dehydrate food waste through high temperature heating or through slow turning and agitation over a longer period of time. Outputs from dry systems can be cured into mature compost onsite or transported to a dedicated compost manufacturing facility.
What is in-vessel composting?
In-vessel composting systems allow you to batch your organics – food scrap, yard trimmings, biosolids, manure, animal mortalities are all possible feedstocks – and are popular because they take up less land, produce little to no leachate and odor when operated properly, and speed up organics processing.
Is compost good for plants?
Compost is typically used as a soil amendment, but may also contribute plant nutrients.”.
What is compost used for?
Improves Soil Health and Lessens Erosion. Compost is an essential tool for improving large-scale agricultural systems. Compost contains three primary nutrients needed by garden crops: nitrogen, phosphorus, and potassium. It also includes traces of other essential elements like calcium, magnesium, iron, and zinc.
What are the benefits of composting?
Composting 101. Recycling food and other organic waste into compost provides a range of environmental benefits, including improving soil health, reducing greenhouse gas emissions, recycling nutrients, and mitigating the impact of droughts. July 20, 2020 Shelia Hu.
Why is it important to keep your compost pile moist?
Moisture is essential for composting —your pile should always feel like a wrung-out sponge. Too dry a pile may cause the composting process to slow down. Too wet a pile may create an anaerobic environment, which can cause bad odors and also slow down decomposition.
How to make composting process faster?
To ensure a faster home composting process, you will need to make sure your compost system has the right amount of air and water. As mentioned above, if you are not in a rush for finished compost, you do not have to maintain your waste; the decomposition will still take place, just at a much slower pace.
How big is a compost bin?
A 3-foot cube is the ideal size for a compost bin or pile. You need a large volume of waste to be able to produce a high enough temperature for aerobic organisms to thrive. However, piles larger than 5 cubic feet are not likely to allow enough air to reach the decomposers at the center; they may also be harder to turn. Chop up larger pieces of food or yard scraps before adding to your bin or pile. The smaller the pieces, the quicker the decomposition process will be. A good rule is not to include anything thicker than a finger.
How to get rid of fruit flies in compost?
Here are some things you can do: Increase the carbon-rich browns in your compost pile to help the organic waste dry out. Fruit flies are primarily attracted to greens and will be less likely to linger if you dig a hole in your compost pile and bury greens under a layer of browns. Buy or make a fruit fly trap.
What are the elements that make up compost?
Organisms that decompose organic waste need four key elements to thrive: nitrogen, carbon, air, and water. Since all compostable materials contain carbon, with varying amounts of nitrogen, composting successfully is just a matter of using the right combination of materials to achieve the best ratio of carbon to nitrogen and maintaining the right amounts of air and water to yield the best results. The ideal carbon-to-nitrogen ratio for a compost pile is 25 to 30 parts carbon for every 1 part nitrogen. If your pile has too much carbon-rich material, it will be drier and take longer to break down. Too much nitrogen-rich material can end up creating a slimy, wet, and smelly compost pile. Fortunately, these problems are easily remedied by adding carbon-rich or nitrogen-rich material as needed.
