Rocket Composter B2500

On-site processing of organic wastes with in-vessel composting. In-vessel composting plant 5-7 tons/day. The B2500 Rocket Composter has been uniquely designed and patented. The system comprises a “Double U” shaped hull with a twin longitudinal shaft configuration. This unique arrangement allows much greater mixing of materials which in turn leads to a more uniform degradation. The design also then impacts running costs and maintenance as we can provide a system with no internal support mechanisms for the shafts.

Composting process

• Woody / sewage wastes are shredded and mixed together
• A wheeled loader or similar will be needed to mix/load the wastes
• A heavy-duty shredder may be required depending on the woody wastes provided
• The operator will need to be trained on equipment but also in the management of the incoming feedstock and what requires/does not require mixing and shredding
• The mixed sewage/wood is loaded by the operator into a bulk feed/loading hopper
• The loading hopper belt feeds directly into the composting unit
• The feed rate is 24/7 and determined by the software governing the composting vessel, the system will “feed itself” throughout the day without manual operator intervention
• The main hopper may need filling only once or twice per day
• The Vessel is a continual process system, loaded with wastes daily that gradually process along the unit, being pushed by the weight of the fresh incoming wastes while the shafts agitate the mix
• The material will reduce by weight by c:40% in the process and material that has resided for c:8 days will be automatically ejected by screw discharge onto a belt and into a stockpile
• All this is PLC Controlled
• The vessel is linked to an odour control system
• The vessel is equipped with air injection and air extraction
• The daily compost product will be c:2tonne per composting vessel this will need moving x 2 by loading shovel to maturation bays
• After c: 2 weeks stabilising the compost will be moved into a second adjacent maturation bay
• After a further 2 weeks, the product can be refined further before re-use
• Screening equipment will be required / trommel
• Operator training will be required
• The screening will be x 1 every 2 weeks
