Waste to energy
The majority of operations utilise the GateHOUSE™/ISYSMobile and Mediwaste weighing applications to record all vehicle/container movements for the sites and provide vital management reporting and invoicing capabilities. The sites are tightly controlled and many have integration with driver operated consoles/barrier control systems to provide for efficient turnaround times.
Integrated treatment technologies include:
Incineration/Energy from Waste (EfW) - (GateHOUSE™ Applications)
GateHOUSE™ is instrumental for the data collection at many incinerator/EfW complexes, two of these sites are LondonWaste Eco Park in Edmonton and the new Cory Riverside Energy from Waste facility at Belvedere in the London Borough of Bexley- an important strategic river-served waste management facility for London.
Energy from Waste (EfW) generates both electricity and useable heat in the form of steam or hot water for local industry, while safely treating non-recyclable residual wastes.
Anaerobic digestion - (GateHOUSE™ applications)
Anaerobic digestion is a renewable energy technology that captures gas (methane) from the decomposition of organic materials, such as manure and slurry; sewage sludge and food waste. By harnessing the natural process that occurs when organic matter is broken down by bacteria in a closed vessel the biogas produced can be used as an energy source for both heat and power.
In-vessel composting - (GateHOUSE™ applications)
The in-vessel composting (IVC) process is aerobic. Once the material is sorted and shredded, it is processed in an enclosed building where optimum temperatures and oxygen supply are maintained to accelerate the composting process.
Mechanical biological treatment - (GateHOUSE™ applications)
MBT is the name given to several processes that are used to treat the waste that arrives at the plant. Several processes are used for preparing and separating the waste when it arrives at the plant. The organic fraction gets mixed with water and processed to recover any more recyclable materials, such as sand or plastic, and to produce slurry. Light material is incorporated into a High Calorific Value Refuse-Derived Fuel (HCV-RDF) and heavy residue is reused as aggregate.
Autoclave - (Mediwaste applications)
Autoclave treatment technology specialists provide a viable ‘greener’ alternative to landfill. The processes are two stage – sterilisation at temperature and pressure followed by mechanical separation.
A combination of the steam and pressure raised internally and the rotation of the vessels results in a reduction in volume of the input waste material by 60/70%.
Rotoclave - (Mediwaste applications)
Rotoclave® systems provide one of the most cost effective methods of treating medical waste, as well as the highest level of sterilization of any alternative treatment.
The Rotoclave® (rotating autoclave) system utilizes a pressure vessel, fitted with a unique rotating internal drum that accepts waste materials in unopened containers and subjects them to agitation. The Rotoclave® operations are governed by a Process Logic Controller (PLC), to ensure that the parameters of time, temperature and pressure required to sterilize the waste, are met and continually maintained. After the Rotoclave® processing is complete; the fully sterilized materials are automatically discharged.
