Waste Management
We have expertise in all aspects of Wastes Management, involving domestic, commercial, industrial and clinical wastes. The disposal of wastes is of increasing concern internationally in terms of both economics and conservation of the environment. Efficiency of operation with proper environmental control is essential in the handling of wastes through treatment plants and recovery techniques, through promotion of reuse and reduction of generated wastes, and through strategies underpinned by a targeted use of landfill capacity. We can provide expertise in the following areas:
- Energy from Waste
- Gas Extraction
- Transfer Station
- Materials Recovery Facilities
- Liquid Waste & Leachate Treatment
- Solid Waste Handling
- Anaerobic Digestion and Composting
- Waste Strategy
- Landfill Design and Management
- Planning and Permitting
- HACCP Monitoring
- HAZOP and SIL Assessments
Featured Projects
With limited availability of landfill space, waste disposal is a major problem in Devon. In an effort to address this issue in an environmentally sustainable manner, Exeter City Council was the first authority in Devon to introduce a two-bin, alternate week recycling collection. To coincide with the scheme, the Council established its first Materials Reclamation Facility (MRF). The City Council's former vehicle maintenance workshop was demolished to make way for the new facility, as this building was too small, and its roof not high enough, to house the required equipment. We provided detailed design for the new MRF. read more
Viridor Waste (Thames) Ltd operate an existing solid waste landfill site at Beddington near Croydon, South London. With tightening legislation on landfill licensing and reductions in disposalcapacity, Viridor have developed the facility and invested in ‘new’ technology to maximise the remaining solid waste landfill capacity. This project is for the provision of a solid waste reception building housing a Dano Drum for processing 110,000 tonne/annum of the waste to separate out the organic and small materials, known as Dano Fines from the larger rejects material. The reject material, being approximately 50% by volume, is taken to landfill, whilst the Dano Fines material is further processed by two-stage composting to meet the requirements of the Animal By-Products Regulations. read more
The plant is sized to handle a varied waste stream (municipal, clinical, commercial, industrial, rubber tyres, liquid, etc.) of 120,000 tonnes p.a. and recovers 5,500 tonnes of metal for resale. It replaces a similar size mass-burn plant from the 60’s unable to meet current emissions standards. The new plant comprises a waste reception hall, solid waste separation, shredders, processed waste storage, 2 fluidised bed boilers providing steam to a 10.5 MW turbine generator unit and providing 8.3 MW electrical power available for net export. This project had a long project development phase as it was one of Scotland’s first PFI projects. read more
