Food waste is a new energy source that ends up decomposing in landfills, in this manner releasing greenhouse gases into the atmosphere. Food waste disposal is a difficult process unlike junk removal and is not easy to recycle since it contains high levels of sodium, salt and moisture and is mixed with other waste during collection. Main generators of food wastes include hotels, restaurants, supermarkets, residential blocks, cafeterias, airline caterers, food processing industries, etc.
Food Waste Management Strategy
The amount of food waste is progressively increasing and a proper food waste management strategy needs to be developed to ensure its eco-friendly and maintainable disposal. The two most corporate methods for food waste recycling are:
Composting: An action that breaks down recyclable waste by naturally occurring micro-organisms with oxygen, in a bounded vessel or tunnel.
Anaerobic digestion (AD): A treatment that breaks down decomposable waste in the absence of oxygen, producing renewable energy that can be used to generate electricity and heat.
What is on-Site Food Composting?
Perhaps the eco-friendliest method of food disposal, composting is also one of the oldest methods of food disposal and recycling that we know. It permits food to decompose naturally and then use that procedure’s results as a fertilizer for current food crops. It is possibly the most ecological method of food disposal.
How Does On-Site Food Composting Work?
Composting is part of science, needing more than just foods to be used. Newspaper or torn-up cardboard is energetic to balance the compost’s acidity and heat, soil containing the micro-organisms guilty for the decay of the foods, and air are all essential to this process. Unlike anaerobic digestion, where no oxygen is needed, this is an aerobic process that needs air. The compost must also have a good balance of water, not enough and the micro-organisms will not flourish, too much and they will drown and the decomposition process will go wrong, producing mound and mildew which is not supreme. To circulate enough air and reassure a rapid composting process, the food and paper or wood chips should be alternated, each with a layer of soil in between, and the whole mound should be wisely turned every other day. In ideal conditions, the composting process can be completed within just a few weeks. The result will be a rich and nourishing fertilizer that can be used on flower beds, vegetable gardens, and planters.
How Much is Food Waste Recycled in the UK?
Food waste refers to the food or food products that are thrown away as opposed to being consumed. Food waste occurs for a variety of reasons. Perhaps the food has gone out of date or you simply purchased too much. Though, unsuitable disposal of food waste, particularly from large businesses, has massive implications on the environment.
We produce around 10 million tons of food waste in the UK, but only 1.8 million of this waste is recycled.
