In vessel composting plant 5-7 tons/day.
The B2500 Rocket Composter has been uniquely designed and patented.The system comprises of a “Double U” shaped hull with 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 on running costs and maintenance as we are able to 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 are loaded by 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 byc: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 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 week 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
- Screening will be x 1 every 2 weeks
Why use B2500?
- High temperatures (+60DegC) achieved to ensure pathogen kill
- Minimal footprint for equipment – minimal building space required
- Minimal labour requirements – low operator interaction with equipment
- Enclosed process – no attraction to birds / vermin
- Bio-filtration on site – vented gases are processed through special organic medium to control / eliminate odours
- Simple monitoring of process / adaption of process from “desktop”
- Recognised / regulated technology in Europe for the treating of organic wastes
- Produces sterile biologically degraded material that can be used as compost / soil improver
