The integrated food waste management using vermiculture-vermicomposting technology
There are many ways to reduce the food waste, but the food waste is always out of there in our modern society. Food waste is any food that is discharded or uneaten by human. It seems impossible to stop the food waste production and accumulation. How can it be? Nearly half of food produced worldwide is waste. The loss and wastage of food occurs at all stages of the supply chain during production, postharvest, processing, retailing, and after consumption.
Based on the report of Food and Agriculture Organization (FAO) of the United Nations: Global Food Losses and Food Waste, distinguishes between food loss and food waste. Food loss measures the decreases in edible food mass, that loss includes weight originally meant for human consumption also used for some other purposes, such as fuel and animal feed. Food waste is food loss accuring during the retail and final consumption stages due to the behavior of retailers and consumers e.g. throwing away of food. In low-income or developing countries most food waste occurs during production and postharvest, while in developed countries much food is wasted at the consumption stage.
According to the CBC News business section reported at the end of last year December 2014, in the case study of Canada, for about 50% of food waste can be described in detail that distribute in 4 major losses. About 20% of food waste happens by food manufacturing and processing. 10% of food waste happens on a farm, before even entering the distribution system. Retailers waste another 10%. Households, restaurants and hotels waste a further 10%.
Food waste is a complex infinite resource and a very diverse in quality, quantity and continuity of the waste proportion and combination. It needs universal recovery process and strategy to ensure optimized the management of the available technologies and recapture of different high added value through the end-products such as high quality of protein and compost from the food waste sources. Safety and cost issues are the utmost important parameters in the realization of food waste management. On the other hand, cleaner production of waste by reducing the food waste is always the cornerstone for the integrated food waste management rather than using more end of pipe technology.
The conventional flow of food waste from the source of pollution usually starts from garbage bins to the collection trucks and then stays for a while at the district garbage stations before distributed to the traditional food waste recycling companies such as in-vessel composting facilities to produce regular compost for plant and/or anaerobic digestion facilities to produce biogas for electricity.
The breakthrough processing of food waste becomes energy for growing compost worms (protein) and beneficial soil microbes are associated with the high quality of worm castings or vermicompost using vermiculture-vermicomposting technology that ranged from simple windrow system to fully automated continuous flow-through vermicomposter. It is the natural way of the environmentally friendly approaches for a better local habitat and profitable solutions for health. The food waste need to be macerated, homogenized, screened and pressed to reduce the moisture prior for pre-composting before offering to the compost worms and their symbiotic beneficial soil microbes.
The compost worms or red wigglers have a high reproduction rate, a short life cycle (2 months) to produce the offsprings, and a high longevity (up to 4 years). Furthermore, they are fast growing and easy to culture. They will produce protein for animal feed, enzyme lumbrokinase for anti blood-clot in human, antibacterial protein to eliminate the human and plants pathogens, and high quality of worm compost or vermicompost which is rich in available nutrients, plant growth regulators/hormones, humic substances (fulvic and humic acids), and high in beneficial soil microbial activities for plant.

The clockwise sequence of the integrated food waste management using vermiculture-vermicomposting method will increase the value of the conventional composting products by producing worm protein for feeding fish and supreme vermicompost for indoor and outdoor plants.
