B2500 Rocket Composter

B2500 Rocket Food Waste Composter

A solution for industrial scale projects

The B2500 is the largest composter in our Rocket range, making it suitable for small scale municipal and remotely located oilfield worker camp environments.

This twin shaft composting system can process up to 6,500 litres of food waste per day, and is ideal for dealing with high volumes of food and green waste, as well as sewage sludges and animal wastes.

  • Description
  • Specification
  • Case studies

Like its smaller sister model the B1400 the B2500’s internal twin agitator shafts, alongside a unique patented w-shaped hull, ensures less compression of materials and airflow through the composting mass. The shafts have no internal support structures, meaning there’s no interior maintenance requirements and no obstructions to the flow of material either.

An integrated PLC control system fully automates the process too intelligently feeding the composter from an attached bulk feed system and controlling the rate of compost output, thus minimising the need for operator interaction.


The B2500 comes with a whole host of options and ancillaries to tailor the system exactly to our clients individual needs. From mixer shredder feed systems, outfeed conveyors, air injection and fully remote monitoring options to a name a few we can supply your site with the perfect solution.

The machine creates a nutrient-rich compost resource in just 14 days, from organic wastes such as cooked and uncooked food waste (including CAT3 meat), sewage wastes, and bioremediation, alongside garden, green and animal waste (including some types of bedding).










Up to 6,500 litres of food waste per day*
*This is determined by the feed materials used, loading frequency and operating conditions. Please get in touch if you need any advice on how to achieve maximum throughput.

120/240 bin loader hopper and screw conveyor

Floor-mounted, stainless-steel hopper equipped with hydraulic bin loader to lift and tip 120/240 wheeled bins. Shaftless screw conveyor from the hopper bottom to the composter vessel inlet.

Bio-mixer hopper & screw conveyor

Twin-shaft mixers in a high-sided hopper mix and blend up to 10 tonnes of material using a 37kw drive. The outfeed from the unit is controlled by the composter PLC, to feed automatically via a shaftless screw conveyor to the composter vessel inlet.


Constructed from 304 stainless steel, with plenum and air distribution system. Organic filter media inside (supplied by customer) removes VOC’s to eliminate odours.

Case studies

The B2500 Rocket Composter is the go-to machine choice for the efficient municipal-scale composting of organic waste. Here are some of our favourite projects…


BP Indonesia

Two B2500 Rocket Composters and a Dehydra Dewaterer are currently converting food waste into compost at BP’s multi-million-pound Integrated Waste Management Facility, at a gas pipeline expansion project in Indonesia. And this solution is also creating jobs for the locals.
