Enzymes eat up brownfield waste

MATERIALS

RUSSIAN enzymes could be the answer to treating dangerous waste material left in UK landfill and construction sites, according to Enzyme Tech.

The Essex-based company developed a blend of enzymes, sourced from eastern Europe, that can help remediate building sites and dissolve hazardous wastes such as engine oil.

The enzymes stimulate microbes and organisms that are found in soil and fuel.

These microbes break down fuels and any other natural hydrocarbons into safe chemical elements and compounds including carbon dioxide, oxygen, water, carbon and other bi-products of the feeding process.

The treatment could be useful for contractors working on brownfield sites in town centres and road building projects that cut through contaminated land.

Vincent Harper, managing director at Enzyme Tech, said: 'What is left after the treatment is a completely nonhazardous and natural.

'Wherever the pollution has gone the bacteria follow and break it down.'

He claimed the process could be used to treat contaminated sites in-situ and at licensed hazardous waste sites.

He said: 'Just one gallon of engine oil can pollute approximately one acre of land.

'Recently there were around 250 sites that were licensed to accept hazardous waste but now there are only five.This will increase the disposal costs of hazardous wastes. '
