Choosing the correct trailer to carry Food Waste at 44 tonnes on UK roads is a tricky decision. Offals (or other loads linked to offals) are often mixed with other abatoir or rendering and food waste products - hides, bones, feathers and blood or even whole carcasses and animals. The primary consideration when choosing a trailer and it's options is the quantity and proportion of free liquid in the Food Waste load carried. Does the trailer need to be watertight at the rear door? Will there be sufficient liquid depth and pressure to find leaks in the floor welds, door, sidewalls and headboard and seep out? Will other items such as bones, heads, horns etc scrape or puncture the body of the trailer? Will the load of Food Waste move and surge within the trailer under acceleration and deceleration. Often in Food Waste waste transport there is a need to have drainage plates in the trailer and drainage taps in the base of the trailer. Will the trailer be stood loaded and unsupported for long periods of time? Will the trailer be sheeted or sealed lid? There are safety and operating considerations in purchasing the correct trailer for Food Waste around safety of releasing material from the rear door.
Newton Trailers' current first choice trailer for the transport of Food Waste is: STAS 65 cuyd Watertight Tipping Trailer
Sales Options For Food Waste Transport: Watertight door, internal drainage plates and taps, surge plates, internal doors, automatic sheet systems or automatic solid roof closing systems for Food Waste. VWS weighers with GPS location trackers and cameras for food chain traceability and animal disease control.
Alternative options: Turner Autogate Door
Seasonal Hire: No but there are peak food waste times of year such as Christmas.
Tascc Product: No
Product Density: 900 kgs/m3
Trailer Volume: 65 cuyd - the trailers are often half full. The extra capacity allows surge and other less dense versatility.
Region: Not regional - it is a pan European trailer type.
9 Million Tonnes of Food wastes are produced per year.
Food wastes are produced both domestically and by business. Much household food waste is composted in the home. Most food waste is removed in small bins and removed to municipal centers for bulk transport away. Business waste varies in the bin sizes from 100 liter to full 29 tonne trailer loads. At the business or domestic door most people pay a contractor to remove the waste. Once in a central location the food waste begins to have positive £ per tonne as at scale it is a raw material to compost, fertilser or energy feedstock in Anaerobic Digestion energy plants. The industry is highly regulated for human and animal health reasons such as water course protection, foul smells and human and animal disease reasons.
Watertight tipping trailers such as the excellent STAS Watertight tipping trailer are used on more liquid wastes. Typically this may require sliding lids and side drainage. Drier food waste can move in more standard tipping trailers with good rubber door seals and automatic sheet systems. If the food waste is less dense walking floors become useful as they are able to move up to 100 m3 in a single load. It is possible to purchase water tight moving floor trailers. However it is technically more challenging to make such a trailer and maintain it's water tight integrity. Many companies moving bread wastes and bulky food wastes use water tight walking floor trailers made by companies such as Knapen Trailers of Holland - the larges floor manufacturer in Europe. These are available with Automatic Sheet systems or sliding lid systems.
Watertightness is not easy to achieve in a 30 tonne loaded trailer. A complete rear door seal unbroken in the corners is a must. Thicker inner face body side planks is preferrable - say 4.2mm not the normal 2.8mm. This allows a better weld and reduces wall flex. Sawtooth rear door is the best, followed by Turner Autogate Door. Plenty of clamps. Remote door release prevents full welly boots and swept back hair. Reinforced door to prevent bowing and side leakage. Fully certificated water tight test ex factory on EVERY trailer. Straight-frame body NOT STEP body. A step body suffers surge pressure at the step and promotes weld fractures and leaking. Fork lift bump strips on the outside. Fill level indicator on inside to prevent over loading. Drainage sides and taps reduces liquid pressure. Inclined rear door reduces pressure on the door base.
As discussed here Food Waste and Animal Waste Trailers are a specialist sport. They require careful operational management and safety items. The number of companies with this capabilty it therefore more limited:
Fabra UK: Foodchain and Biomass Renewables Associationan excellent source of information for foodchain and rendering knowledge. Visit there site and learn about Food Waste transport and Food Waste trailers in the UK.

Food Waste Trailer Option: STAS Sawtooth Watertight Door. Hydraulic powered wedges force the door closer and closer to the rubber seal.
Food Waste Trailer Option: internal drainage. Punctured aluminium side strips allow the load to drain internally to valves.
Food Waste Trailer Option: Internal Rear Doors. Internal doors are possible to allow different product streams to be carried in the same trailer eg Food Waste in the back half; feathers in the front half.
Food Waste Trailer Option: Bolt on surge plates front and rear. Reduce spills under braking and acceleration. Reduces the chances of the lady with the pram getting covered at the zebra crossing and recharging her dry cleaning bill to you.
Food Waste Trailer Option: VWS Weighing System: Traditonally Food Waste trailers have not taken weighing sytems. But these systems now allow live GPS tracking of the trailer and camera recording and logging of loading and unloading events for auditing.
If the liquid element can be drained at the time of loading this helps to achieve greater efficiency in achieving 30 tonne payload of higher density Food Waste or food waste or animal by-products. It is a customer option to add external taps for decanting the liquid and blood before transport begins. Any number of drain taps can be fitted. Typically 2 per side - one towards the front of the body and one towards the rear. There will be a requirement to regularly wash the drainage perforated aluminium out and remove debris caught inside. This is accepted practice in the industry although there is not normally a queue at the door to do that work?
