Untha shredders process C&I waste into fuel
Sita UK has invested in three high-specification Untha shredders at its new solid recovered fuel (SRF) plant, part of its Integrated Resource Recovery Centre (IRRC) in Birmingham. The shredders are set to produce 60,000 tonnes of SRF a year, which will be used in Cemex UK’s plant in Rugby.
One XR pre-shredder (pictured above) and two TR post-shredders will process commercial and industrial waste from the Midlands into SRF with a particle size of less than 30mm.
The shredders will operate in conjunction with trommels, air shifters, magnets and eddy current separators to ensure the specification is achieved. A near-infrared unit will be used to measure output quality in real time and ensure the SRF has the correct chlorine, moisture content and calorific value.
Sita UK strategic development manager Tim Hughes said: “The plant enables us to offer our customers a recycling solution which is cost- effective and avoids the use of landfill. It is also great to see that the SRF will stay and be put to good use in the Midlands area.”
Engineering specialist Sutco designed the state-of-the-art SRF production plant. The IRRC aims to divert up to 200,000 tonnes of waste from landfill each year.
Fast and legal transaction processing
Scrap metal transaction software program Metaltrack has now processed more than £10m in transactions since the end of 2012.
Designed with Dudley scrap metal merchants Mason Metals, the program was designed specifically to handle transactions in line with the latest legislation and police initiatives. The system completes the weighing and waste transfer notes (WTNs), then stores the customer’s ID electronically.
Mason Metals managing director Andrew Jones said: “The WTN element is very quickly completed, and for returning customers who are set up with bacs, transfers leave within seconds.
“Cheques are also electronically printed, which again saves time. It means we process our clients legally, which is most important to us, and quickly, which is most important to them.
“Metaltrack has improved the administration to our account-based clients who can receive documents and payments electronically - which many prefer.”
Vehicle movements are recorded for safety
Hills Waste Solutions (HWS)has specified the latest hard disk recording technology from Innovative Safety Systems for its 13-strong fleet of RCVs that carry out commercial waste and recycling collections across Wiltshire.
HWS divisional director Steve Burns said: “We have been using reversing cameras for four years and the number of accidents has reduced significantly. The digital video recorder (DVR) systems from ISS are an excellent additional safety tool for drivers.
“They and provide a clear record of each vehicle’s operational movements which is useful for staff training and service monitoring.”
The ISS system was recommended to HWS by Wiltshire Council, for which it handles municipal waste.
Council transport officer for environment services fleet Ian McKinnon said: “We trialled the ISS system a couple of years ago and, due to efficiency of the products and the longer warranty period, we decided to convert to ISS from our previous supplier.
“Since then we have installed ISS DVR systems and reversing radars to around 30 vehicles.”
Council renews refuse vehicle contract with SFS
Hyndburn Borough Council is to retain Specialist Fleet Services (SFS) as its vehicle provider, signing a three-year contract with the contract hire and fleet management company to renew its refuse collection fleet.
Council head of street scene Steve Riley said: “SFS provided the best combin-ation of price and quality in response to our tender.”
The vehicles to be provided by SFS are six Dennis Eagle Olympus narrow chassis with Terberg OmniDEL Xtra bin lifts, delivered in stages starting this September.
Mixer helps with AD system throughput
Weltec Biopower has developed a rugged liquid input system which prevents outages, so safeguarding the technical stability of anaerobic digestion systems.
The company claims that productivity is increased at the same time, due to the option to flexibly mix the input materials as an alternative to using expensive maize silages.
It claims that with its Multimix system, fibrous and sticky input materials such as grass silage, solid manure or co-substrates are reduced in size, so increasing their surface, making them more suitable for bacteria. Multimix also separates foreign matters such as rocks or metals before input, so decreasing the risk of damage to the pumps and agitation systems as well as build-up occurring in the fermenter and pipelines.
Weltec claims the system aids decomposition and allows for a faster and greater gas yield, as well as reducing the risk of floating or sinking layers developing in the fermenter.
