Technically speaking

Black & Veatch's Frank Rogalla looks at moving bed biofilm reactors

Metal recovery from electronic scrap

Researchers at Imperial College London have developed a novel aqueous leaching and electrowinning process for recycling metals including tin, silver gold, lead, copper and palladium from electronic and other scrap material.

Renewable fuel cell

Proton Energy Systems is developing a regenerative solar/proton exchange membrane (PEM) fuel cell demonstration system. The company plans to incorporate its Unigen regenerative fuel cell system, which includes a hydrogen generator, hydrogen storage tanks and PEM fuel cell, with a US Navy supplied solar photovoltaic array.

An impressive vision – but where is the route-map?

The Energy White Paper paints a picture of a low carbon future. But while long on vision, it is short on the detail of what needs to be done, argues Simon Napper

Calling in the effluent experts

Process Engineer at Atkins Water, Fred Gould, discusses the benefits of using an integrated and inclusive approach to dealing with industrial wastewater.

Biotechnology shows its liquid assets

Three recently completed demonstrator projects, part of the DTI's BIO-WISE programme, have successfully proven that biotechnology processes can remove pollutants from waste streams across a variety of industries.

Brownfield developments: an unattractive prospect?

The very term 'brownfield' suggests an unattractive prospect - dirty and unproductive - especially by comparison with the image of sunlit acres conjured up by the alternative: 'greenfield'.

Biological remediation – no longer a black art

The first ex-situ bioremediation project of the 21st Century under the CL:AIRE initiative has been successfully completed at Askern Colliery, near Doncaster, for the regional development agency, Yorkshire Forward.

Driving forward land remediation

These are challenging times for contaminated land. The treatment and reuse of brownfield sites is becoming increasingly driven by legislation. Churngold Remediation explains what might happen.

Cleaning up for the future

The SAFEGROUNDS Learning Network aims to encourage good practice in the health, safety and environmental aspects of managing contaminated land on civil nuclear sites and defence sites.

Research, development and remediation

CL:AIRE (Contaminated Land: Applications in Real Environments) is promoting the development of sites of national significance to enhance collaborative research on big issues in the remediation of contaminated land. Two such sites are CoSTaR and SIReN.

Remediation: It’s a question of technique

The Environment Agency (EA) has begun a project to review the application of available and emerging techniques for the characterisation of land contamination. Jason Rayfield reports.
