PEHD membrane sealing systems for retrofitting in existing landfill site

by ELD Environmental Leak Detection GmbH     based in Berlin, GERMANY

It is also possible to retrofit a monitoring system in existing surface sealing liners without impairing the synthetic liner sheet or the immediately adjacent functional layers. For this purpose, cable trenches must be dug in the recultivation layer above the drainage layer. The detection cables are then laid in these trenches.

PEHD membrane sealing systems for landfill surface liners

by ELD Environmental Leak Detection GmbH     based in Berlin, GERMANY

Unlike base liners, surface liners are not buried at some point under many metres of waste and instead are usually protected over the course of many years only by a 1-metre thick mineral layer. As a result, there can be uncertainty about the integrity of their leak-proofing characteristics, particularly if the land is subsequently used for other purposes; however, at the same time, repairs are also possible at reasonable cost if the location of any damage can be established.

Treatment and dewatering of rejects for pulp and paper industry

by BELLMER KUFFERATH Machinery GmbH     based in Düren, GERMANY

Dewatering rejects to maximum dry contents represents an essential process step both from an economical and ecological viewpoint, especially in waste paper based paper mills but also in pulp mills. The following goals shall be achieved: high heating value for stable and ecological incineration without co-firing, reduction of landfill and transport charges.

Landfill Piping Solutions

by ISCO Industries, LLC     based in Louisville, KENTUCKY (USA)

Landfills are active environments. Through natural processes of rainfall, condensation, and decomposition, landfills themselves produce a liquid waste stream, called leachate. Often the leachate contains hazardous materials, so properly managing a landfill requires handling the waste. ISCO offers products and services to help manage leachate including HDPE landfill pipe, perforated and slotted pipe as well as custom fabricated fittings.

Landfill lining

by CETCO     based in Hoffman Estates, ILLINOIS (USA)

GCLs have become the gold standard clay component of composite lining systems used in industrial, hazardous and municipal solid waste landfills. Used alone or in combination with a geomembrane in a composite cover system, GCLs provide significantly lower permeability, improved ease of installation, an increased amount of usable space. In many cases GCLs are more cost-effective than traditional compacted clay liners. GCLs are also not subject to deterioration from differential settlement and freeze-thaw cycles, which can damage traditional compacted clay liners. Important design considerations for GCLs in landfill caps include confining pressure, and potential for ion exchange and desiccation.

PEHD membrane sealing systems for landfill base liners

by ELD Environmental Leak Detection GmbH     based in Berlin, GERMANY

There are several phases of preparation of landfill base liners, starting with the positioning of the membrane, until these can be covered with several metres of refuse. These membranes may be damaged during preparation, but can also be inspected and repaired. It is advisable to undertake inspections at regular intervals.

Mixed Municipal Solid Waste Sorting

by TOMRA Sorting (TITECH)     based in Mülheim-Kärlich, GERMANY

Traditional (manual) or semi-automated techniques, however, are only able to recover low levels of separate materials from mixed municipal waste streams and mean considerable content going to landfill. In contrast, TOMRA Sorting’s fully automated, state-of-the-art, sensor-based municipal sorting systems convert complex and varied - even dirty - municipal solid waste streams into high quality, separated, marketable output. The systems also make manual sorting unnecessary, thus reducing labor costs and material loss, while increasing efficiency. Operationally, through using detection techniques such as near infrared (NIR), x-ray transmission (XRT), color line cameras and metal sensors in combination.
