In-Vessel Composting of Segregated Wastes and Food Processor Wastes

The ciVic® process of in-vessel composting delivers:
The ciVic® process starts with the delivery of wastes, which are deposited from the collection vehicle into the waste reception area. The waste is then fed by a mobile loading shovel into a shredder, which reduces the size of the waste material, breaking up any solid or bulky elements (wood etc). The shredded waste is fed into the top section of the ciVic® digestion tower. Each batch of material is processed in a closely controlled environment with all critical parameters being constantly monitored and used to control the agitation of the material and addition/extraction of air as required. The waste is kept under these tightly controlled conditions for 6-10 days, during which time the biodegradable content (paper, food waste, grass cuttings etc) is rapidly digested to form compost, water vapour and carbon dioxide. The system is completely closed, allowing total control of the carbon dioxide produced - this is passed through a bio-filter to ensure that no odours escape. A major advantage of the ciVic® system is that every element important in the process is constantly monitored and controlled all the time. All elements and operations are recorded by the bespoke Supervisory Control And Data Acquisition SCADA system and logged for each individual batch. This provides a complete history showing the batch identity, batch size, water additions residence time/temperature achieved and any other significant details. All of which can be formatted to the operators requirements to enable full compliance with both the Animal By Products Regulations and the operators own quality control system.
