Wet Waste Treatment

Wet Waste Transfer, Treatment and Recycling

UBU ensure that waste received at our treatment plant is transported and treated using the correct EWCs. UBU understands that the Waste Producer has a responsibility to ensure their waste is transported, treated and or disposed of using the correct Environmental Waste Codes. We ensure that there is a full Audit Trail of all applicable waste from ‘Cradle to Grave’. The EWC used for general Road sweeping and jet vac tanker gully waste is 20 03 03 and this EWC should be listed on the ‘Permitted Waste Codes’ of any disposal facility which receives Road sweeper waste.

Other permitted wastes include; leaves, litter, mud, dust and aggregates. UBU’s Jet Vac Whale Tanker can collect and remove waste from a diverse range of sources, such as; drains, sewers, gullies, septic tanks and storage tanks.

UBU Environmental Ltd is licensed through the Environment Agency to collect, keep and treat wet waste at our own premises in Manchester.

UBU Environmental is fully licensed to take away waste under the following codes:

Wet Waste Treatment

Where construction sites are not licensed to dispose of Road Sweeper waste on suitably approved locations on site, UBU Environmental Ltd. can provide an environmentally sound, and extremely cost-effective alternative to Landfill.

This system allows the recovery and re-use of recycled material including the use of sand and stone for offsetting virgin materials. This includes pipe bedding, landscaping uses and sub-bases, resulting in far-reaching environmental benefits.

Annual increases in landfill tax have significantly increased the costs associated with disposal of road sweepings and gully waste for companies who offer reception and collection services for this waste. As disposal costs continue to rise, the commercial argument for cleaning Road Sweepings and Gully Waste becomes even stronger.

Road sweeping material enters the UBU treatment facility which uses density separation and attrition to separate organics and trash from the aggregate. The treatment facility has the ability to receive and process both wet wastes and dry waste, with a combined throughput of up to 25 tonnes per hour, or 250 tonnes per day.

Depending on the composition of the feed stock, the treatment facility has the ability to produce up to 50 tonnes per day of washed aggregates and up to 125 tonnnes per day of washed sand. This system allows the recovery and re-use of recycled material including the use of sand and stone for offsetting virgin materials. The washed aggregate is dewatered, and the smaller fraction is separated for further classification to capture valuable metals. After further removal of contamination, the aggregate is sized into two ranges to allow for use in different applications.

The wastewater is then chemically treated before undergoing further treatment to create thickened sludge. The recycled water is sent to the water storage tank for recirculation around the system. Approximately 90% of the water in the system is recycled for re-use. The sludge is sent to a buffer tank for further treatment..
