Why We Manage Food and Organic Waste?

We are one of the top producers of waste in the world. With the amount of rubbish that we produce, it is necessary that we are aware of how to manage and dispose of it efficiently and responsibly.

Organic waste should not be a source of environmental pollution that has to be gotten rid of by putting it in landfills or burned in incinerators, as this could cause other pollution problems. It should be a valuable resource that can be transformed into marketable products providing employment and profits.

One of the most known processes in organic waste management is composting. Basically, in composting you collect organic wastes, process them, and they’re available for use. You can then use the compost to enrich your plants and garden with nutrients and other natural materials. In this way, you transform harmful organic products into a safe and valuable compost.

How to manage organic waste and provide solutions for organic waste management

1 Food Waste

Food waste represents a significant proportion of organic material found in residential waste. It is generated primarily by the residential and ICI sectors, and can be either post-consumer, originating from residential and commercial kitchens (i.e., restaurants and hospitals), or pre consumer, coming from distribution and retail agents (i.e., transporters and supermarkets). Food waste has a high moisture content, which can lead to the generation of leachate and odors during handling and processing.

2 Leaf and Yard Waste

L&YW consists of green grass clippings and thatch, leaves, weeds, brush, and small tree pruning. L&YW is generally small enough that it does not require grinding or shredding before being processed through composting or anaerobic digestion.

3 Animal Manure

Animal Manure is common in daily life, including poultry manure, livestock manure and so on. Animal manure compost contains multiple necessary plant nutrients, including potassium, phosphorus, nitrogen and a variety of micronutrients. Therefore, composting animal waste is a good way to convert animal waste to valuable organic fertilizer. As high-quality fertilizer, composted animal manure can be used as soil amendment and excellent fertilizer.

Options for Organic Waste Management

1 Biogas production with central collection and pre-treatment (collection in bins)
2 Biogas production with decentralized collection and pre-treatment, respectively
3 Collection with ordinary mixed waste for incineration
4 Composting with decentralized collection and pre-treatment


Composting is the aerobic (in the presence of air) decomposition of organic waste, and it significantly reduces or even prevents the release of methane during the breakdown of organic matter. Compost can be used to return nutrients to depleted soils and support moisture retention, which boosts crop productivity – it can increase crop production by 15–25%, while reducing the use of chemical fertilizers. Compost can also be used for urban forestry initiatives, as it supports the early growth of seedlings.

Anaerobic digestion

Anaerobic digestion is the decomposition of organic waste in controlled conditions using a sealed, oxygen-free tank. It creates biogas – a renewable energy resource that can be used or sold to generate revenue – as well as avoiding the release of methane into the atmosphere. Biogas can be used locally to produce hot water and for cooking, for example. It also produces digestate, a bio-fertilizer that can be used as a bio-based supplement for food production.

Rapid Treatment Technology

Rapid Treatment Technology may be the key to solve the problem of organic waste recycling for thousands of years. By adding enzyme and sub-material, the organic waste can be composted and odor removed rapidly. The end product of Rapid Treatment Technology is high quality organic fertilizer. It can be applied to agriculture, forestry, fishery, livestock, industry and living organic waste. While composting requires long time and big space for natural decomposition by microbial, the Composting-free Technology can speed up the entire process by applying enzyme. By using the enzyme produced by micro-organism, the organic waste can be converted into organic fertilizer in 3 hours.

As waste management is usually within the power of cities, cities can often implement food and organics waste schemes quickly. This is how cities that are early on a sustainable waste management path can tackle food and organic waste to deliver swift, local rewards. Cities taking the first steps towards sustainable food and organic waste management can reap the biggest and most rapid benefits by prioritizing the segregated collection of organic waste for safe disposal or treatment.
