Food Waste Disposal Stations

The hot topic in today’s food industry is the sheer volume of food that is wasted on a daily basis.  Every 240 litre wheeled bin filled with food waste costs around £240 for food purchase costs and waste disposal alone. Just one bin of food waste per week across 52 weeks of the year could cost a business more than £12,000 a year.  Schools being no exception producing 13% of all non-domestic food waste in England.  This amounts to throwing out 123,000 tonnes per year of which most goes straight to landfill.   This is money that could be saved if a few things were done differently.

Waste management is the process of treating solid wastes and offers variety of solutions for recycling items that don’t belong in landfill. It is about how rubbish can be used as a valuable resource. Waste management is something that each and every catering establishment, school or otherwise would benefit from. Waste management disposes of the products and substances that you have, in a safe and efficient manner.

Food disposal units are a great way to keep your school catering environment sustainable giving you the opportunity to do as much as you want from creating fuel from your food or just reducing the size of your waste.

  • Dewatering – The idea of a Dewatering unit is to reduce the size of the waste created by your establishment by removing the water with in it – most food items carry 80% water. By using the dewatering units to reduce the water content in food waste your catering environment you will notice many advantages especially with in waste disposal costs.
  • Waste Composter – these are designed to recycle food wastes from catering or food service on site. By recycling these wastes on site the need for costly collection and disposal for the waste is eliminated and a useful end product is produced instead.
  • Food waste bio-digester – This way of disposing of food waste is using micro-organisms to digest the food waste while starting the breakdown of fats, oils & grease. Waste water is the only output with no solids to manage.

Why use these methods?

Rotting food waste that is dumped in landfill sites creates methane, a climate change gas that is 22 times more powerful than CO2. It makes sense that any organisation or company with a responsibility for our future environment should look to 100% recycle their food waste and give us a more sustainable future.  This also makes for global and recycling awareness within in the school and promotes good practice – a great example for the pupils to gain.

If your school is struggling with food waste costs or simply wants to promote an ethical way of disposing of food waste, please contact us for more information about how a food waste disposal station can benefit you.

The Problem

Food waste is a major problem for any organisation that produces it. It’s notoriously difficult to process and dispose of safely and efficiently and is the most likely waste stream to contaminate other waste fractions. Most waste streams are relatively easy to recycle. Glass, plastic, aluminium and even metals can be recycled into useful by‐products, but not so much food waste.

The Solution

By utilising IMC’s WasteStation food waste processor, many of these problems are removed or reduced leading to large savings in many areas. Food waste typically represents around 40% of total commercial catering waste. Of this 40%, approximately 77% is liquid. WasteStation grinds the food waste into fine particles, these particles feed directly into the built‐in dewatering system. Through centrifugal action, the WasteStation forces out the excess liquid from the macerated waste. This “grey water” is fed directly to drain, the resulting solid fraction of the food waste is collected in small, easily managed, lidded bins, ready for onward processing. Benefits to St John’s College
Reduce waste collections by up to 80% by reducing the food waste volume and weight requiring collection. By reducing the waste volume, on site storage facility requirements are also reduced. The self cleaning system reduces staff time managing and processing any food waste. Compact design and short processing times ensure low operating costs and minimal use of floor space. Future proof your business. Waste disposal is becoming more expensive year on year and legislation is pushing us to now consider other disposal techniques and move away from waste disposal units and waste to landfill.

Based upon the information provided during our meeting, the potential savings are illustrated below:
