Leachate treatment gets the green light

As part of the expansion of Rainham Landfill Site, Cleanaway is remediating and restoring a 64-hectare area of highly contaminated land. Originally marshland, the contaminated area, prior to Cleanaway's management, was subject to over 70 years of uncontrolled waste deposition, to a depth of up to 10 metres, that terminated in the early 1970s. The area was also the site of a hazardous waste incinerator and a chemical waste treatment facility with the despoiled land later being used for unregulated vehicle breaking (scrap-yards). A sophisticated system of dealing with leachate on the site is described in this special report.

Purpose-built US compactors make a strong impression on UK sites

With landfill under close scrutiny, local authorities and their contractors are subjected to considerable pressure to ensure that landfill operations, and landfill capacity in general, are managed as efficiently and effectively as possible - using the latest equipment and techniques. In this search for "best value", there are lessons to be learned, not least from America, and one company has already made a significant impact with new equipment in the UK, with the introduction of the leading American purpose-built waste compactors - the Al-Jon "Impact" range.

The filtration ‘root’ to wastewater management

Filtration systems manufacturer Goodtech Vanpipe Ltd has recently invested in new mobile laboratory facilities and pilot plants to offer on-site evaluation of process fluid streams and wastewater management. The company aims to show companies with no process water handling how economical and environmental benefits can be made using on-site filtration, and as such is offering a free on-site environmental and process treatment evaluation for any company looking to install or upgrade its wastewater or process water filtration system...plus a ready-to-plant deciduous tree.

Still monitoring after all these years

Continuous monitoring of industrial effluent, to ensure compliance with consent levels, can be prone to long periods of downtime when wastewaters are difficult to handle and their monitoring faces other factors. Through a careful maintenance regime at its Fife ethylene processing plant, ExxonMobil Chemicals has achieved 98 per cent uptime on an instrument installed more than 15 years ago to constantly provide continuous oxygen demand (COD) measurements every few minutes.

DTA downstream

In September last year the Direct Toxicity Assessment (DTA) Steering Group presented the recommendations from its three-year demonstration programme to the regulators, identifying "how DTA could be used to help drive environmental improvements in a cost-effective and practical manner". Kevin Long, Brixham Environmental Laboratory, on what it all means.

Green with Envoy

Mercedes-Benz, Philips, GlaxoSmithKlein and the United Nations Environment Programme all know what it is to have environmental management customer support before they realise they've got a problem.

Data: ins and outs

The MEPI project - Measuring the Environmental Performance of Industry, first reported in IEM February 2000 - has been completed: a robust, quantitative and comparable measure of the environmental performance of firms from a wide range of sectors using nothing but publicly available information. The cost? E0.5m plus two-and-a-half years solid work. The benefits to industry, policy- makers and investors? Immeasurable.

Pay through the noise

Paying for only as much as you want has been extended from mobile phones to consultancy services. All you pay for is the time spent using the software, eliminating the need for up-front capital but still allowing maximum access to a state-of-the-art noise mapping system. Beverly La Ferla reports.

Accounting for environmental performance

Environmental data: that dispersed over a multitude of manual and electronic systems, across ever-increasing numbers of poorly documented spreadsheets, and being used to meet increasingly demanding and complex reporting requirements. Malcolm West, AEA Technology, and Asger Eriksen of recently AEA-acquired Monitor-Pro, argue that with an Environmental Data Management System, it doesn't have to be like that.

Take me to your designer

A golden opportunity to promote energy efficient systems? Or simply too little, too late? Tanya Ross, associate at Buro Happold Consulting Engineers, looks at the revision of Part L of the Building Regulations issued by the DETR.
