Sustainability by recycling food waste

To achieve a sustainable society then food waste must be recycled as opposed to being sent to landfill sites around the country. We all know the problems that our planet is suffering through global warming that is partly  aided by the greenhouse gasses that are produced when food waste is sent to landfill and the ensuing fluctuations in temperature that is suffered around the globe.

green recycleSustainability is something that should have been put into operation by the world’s leaders during the past century but in their defence they did not have the information that the modern day scientists have given us. Live for today and don’t worry about tomorrow cannot be allowed to continue any longer if our children and grandchildren are not to suffer in the future.

By recycling food waste,which is a perfectly acceptable sustainable solution, for this form of waste will certainly help the environmental impact on our planet in the future. Firstly, by diverting the food waste away from landfill will stop the greenhouse gasses being produced and make our planet a better place to live but by actually recycling the food waste, both commercial and residential, it can actually turn a waste stream into a useable commodity.

There are two main area’s where food waste can be recycled and both are fully sustainable.

In vessel composing – This is a process where the food waste is turned into compost.Eco Food Recycling currently take their food waste to a local IVC and the extract below fully explains how this process works.

Eco Sustainable Solutions operate a fully licensed EU Category 3 Invessel Composting facility, allowing us to process cooked and uncooked meat and foodstuffs from source separated and commercial sources. The material is first of all shredded through a 12mm screen and then put in to sealed units (clamps), where it is left for 10 – 12 days to heat up to a minimum of 70c for at least 1 hour to sterilise. The temperatures are automatically monitored and recorded during this period. Once the batch has reached the required standard and is sampled and analysed, it is moved outside for maturation for a further 12 – 14 weeks. After this, the nutrient rich compost is screened (with any plastic residue separated) and used on our turf fields to replenish the soil harvested during the turf process, thereby allowing us to grow sustainable and nutrient rich turf.

Anaerobic Digestion – Is the process favoured by the coalition government and many large corporations within the UK and is explained by wikipedia as below.

Anaerobic digestion is a series of processes in which microorganisms break down biodegradable material in the absence of oxygen, used for industrial or domestic purposes to manage waste and/or to release energy.

It is widely used as part of the process to treat wastewater. As part of an integrated waste management system, anaerobic digestion reduces the emission of landfill gas into the atmosphere.

Anaerobic digestion is widely used as a renewable energy source because the process produces a methane and carbon dioxide rich biogas suitable for energy production, helping to replace fossil fuels. The nutrient-rich digestate which is also produced can be used as fertilizer.
