Commercial Food Waste Collection

We collect all types of food waste throughout the UK if you require a commercial food waste collection, recycling and disposal service contact us today.

What are the different types of food waste?

    Solid and liquid food by-products from agriculture, the manufacturing process or food and drink processing
    Un-saleable food that’s out of date (from shops and supermarkets)
    Leftover food from restaurants and food preparation waste
    Bakery and packaged food waste.

Commercial food waste disposal

What are the legal obligations for food waste disposal?

Organisations must remove food waste from areas where fresh food is present as quickly as possible to avoid cross-contamination.

Food waste must be disposed of in containers that can be sealed shut, are made of appropriately robust material, are kept in good condition, and are easy to clean and disinfect.

You must also have adequate facilities for keeping and disposing of food waste, as well as other rubbish.

Waste stores need to be well designed and managed to keep them clean and free from animals and pests.

When finally disposing of food waste, it must be done in a hygienic and environmentally friendly way, in accordance with your local authority’s rules about the way certain types of food waste must be collected and disposed of.

Enforced by your local food inspectors, there must be no signs of contamination from waste to food preparation.

Commercial food waste bins

What type of bin do you need for food waste?

Under the FSA’s rules, food waste should be disposed of in a durable, easy to clean bin that’s ideally colour coded and sealable to avoid pests, cross-contamination with active food preparation areas and spillages. We will supply the right food waste bins to make sure you comply with the regulations.

As you might expect, we have a wide range of wheelie bins available, ranging from 120-litres to a more substantial 660-litre unit. These units are all compliant with regulations that food waste must be placed in bins that can be sealed (cleaning up after a fox has been through your bins is never a pleasant experience), easily cleaned, and colour-coded to clearly signify its purpose. These bins are complimentary and you, as a business owner, will only have to pay for the collection.

Commercial Food Waste Recycling

How do you dispose of food waste?

It does not matter how carefully food is prepped and served, there will always be food waste. Disposing of food waste in a sustainable and hygienic manner can be problematic if businesses are unsure of the choices available. Broadly, there are four methods of food waste disposal. Let us examine them in turn.

What is anaerobic digestion?

Anaerobic means without needing oxygen while digestion refers to the consumption and processing of food to create nutrients. This helps to understand anaerobic food digesters and also goes some way to showing why these food disposal plants are sometimes called ‘concrete cows’

How does anaerobic digestion work?

They are referred to as ‘concrete cows’ because they work in a remarkably similar way to a cow’s stomach. Waste food is sorted and shredded, removing any packaging materials that might have been caught up with it. A little liquid is added at this point, often waste liquids from food manufacturers, to mix the food matter into a kind of ‘soup’. This is the ‘mouth process’ of the concrete cow.

Moved along to the ‘stomach’, the soup is gently warmed to promote the growth of the anaerobic bacteria and stirred to prevent a crust forming. Then it is left for upwards of sixty days while the bacteria do their job, breaking down the food particles and producing rich methane biogas which can usually be used to power the digester after its initial start. Any surplus gas can be fed into the National Grid or used for other purposes that currently use fossil fuels.

Aside from the gas, the process produces rich fertiliser which can be used on crops to improve harvest and enrich the soil.

What are food waste dewatering systems?

Even fairly dry things can hold a fair amount of water, and food tends to be moist rather than otherwise. Removing as much water from the waste can reduce its bulk and weight by up to as much as 80%.

How do food waste dewatering systems work?

Waste food is gathered and ground into small even pieces, and it is then fed into a long threaded tube out of which liquid can escape but food solids are retained. The screw is then turned, pushing the food particles along into an ever-smaller block, squeezing out as much of the water as the machine is able to. The resulting blocks are smaller and lighter, needing less energy and expense to be transported elsewhere. These blocks of food waste can then be used in cattle feed or converted to biofuels, while the water can be purified and returned to the water system of the area.

What are pump and vacuum systems?

Commercial kitchens need to be kept immaculate at all times, but food waste can be a critical control point fail. Old food, peels, inedible parts of meals (bones and gristle, for example) and expired items need to be disposed of, which generally means keeping this unwanted food in the premises for some time, until shift change or the end of the working day. Pump and vacuum systems whisk old food and debris out of the kitchen using a vacuum-sealed pump system to carry it into a sealed container. This keeps the old food from attracting flies and rats and has the disposed-of foods ready to go when the collection service arrives, so there’s no need to remember to put bins out.

How do pump and vacuum systems work?

Each pump and vacuum system is installed to be sympathetic to the kitchen in which it is installed, with the collection container stored in an appropriate place. It is best to have this sort of system installed when the kitchen is being overhauled with access points at appropriate places, that is to say, where the food is prepared and where plates would be scraped and perhaps other points around the kitchen flow where food might be disposed of. Once the system is in place, the kitchen workers simply put the food into the access point, much as they would into a bin, and the vacuum system pumps it through to the collection tank. These systems tend to be self-cleaning, washing themselves out on a regular basis, using detergents that would commonly be found in a commercial kitchen. The cleaning cycles can be adjusted to cope with increased or decreased disposal amounts according to the needs of the kitchen.

What is on-site composting?

Perhaps the most eco-friendly method of food disposal, composting is also one of the oldest methods of food disposal and recycling that we know. It consists, very simply, of allowing food to decompose naturally, and then using the results of that process as a fertiliser for current food crops. It is perhaps the most sustainable method of food disposal.

How does on-site composting work?

Composting is something of a science, needing more than just foods to be used. Newspaper or discarded brown paper or torn up cardboard is vital to balancing the acidity and heat of the compost, soil containing the micro-organisms responsible for the decay of the foods, and air are all necessary to this process. Unlike anaerobic digestion, where no oxygen is needed, this is an aerobic process, needing 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 mould and mildew which is not ideal. In order to circulate enough air and encourage 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 heap should be carefully turned every other day. In optimum conditions, the composting process can be completed within just a few weeks and the result will be a rich and nourishing fertiliser that can be used on flower beds, vegetable gardens and in planters.
