In recent years Stopford has developed a strong portfolio of novel environmental technologies. Working in partnership with our clients, and our in-house R&D team, Stopford can offer the market a suite of technologies spanning the energy and waste treatment sectors:
Plasma Arc Gasification is an emerging technology that is being used to generate energy from carbonaceous materials. The process operates at sub-stoichiometric oxygen conditions, using a carbonaceous feedstock, to produce low energy synthesis gas (comprising of hydrogen and carbon monoxide) and an inert silicate slag. The synthesis gas can be used as a fuel to generate electricty or alternatively as a precursor for chemical synthesis and fuel production. The vitrified slag is an inert glass which can be used in a number of applications, ranging from tile manufacture to a construction filling material. Gasification serves as a very valuable process for transforming low value feedstocks into marketable products and fuels.
The Encapsu Waste process is a novel ultra-sonic micro-encapsulation process which can be used for the treatment of hazardous waste streams. The process enables the hazardous component of a waste stream to become “locked up” within the encapsulation matrix, turning an undesirable waste into an inert saleable product. The technology presents industry with a novel method for reducing waste disposal costs, whilst increasing the environmental sustainability of the sector.
The matrix constituent separator (MCS) provides a safe, low-cost, onsite, thermal desorption process for the treatment of hydrocarbon contaminated solids.
The treatment modules use patented low temperature thermal desorption technology to volatilise the hydrocarbon component, from the waste stream, to produce oil and inert material.
Stopford’s strategic partners now operate a continuous process pyrolysis plant for the recycling of tyres. The plant handles 43,800 tonnes of waste tyres per annum, producing approximately 22,000 tonnes of recovered oil, 13,000 tonnes of black carbon and 4,500 tonnes of steel. Stopford are currently working with its partners towards the development and implementation of innovative and environmentally sustainable waste treatment technologies.
The isotope recovery technology is a novel method for treating low level nuclear metals waste. The process uses a chemical solution to remove radionuclides from the surface of contaminated metals. The treated metal can be reclassified as free release (exempt) material or as material that is safe to handle. The radionuclides can then be precipitated from the treatment solution and disposed of as low level nuclear waste. The technology presents the industry with a novel, safe, quick and low cost treatment method which will significantly reduce the volume of low level waste being sent for disposal.
