Metro EnviroBind - Overview

Envirobind is a process that is used on site to stabilise and encapsulate contaminants. Envirobind has an excellent global track record and is promoted by the Environment Agency and WRAP as the way forward to recycle contaminated land and significantly reduce landfill.

Benefits

Envirobind, an innovative cost-effective product that remediates contaminated soils and improves their geotechnical properties at the same time. Envirobind is a stabilisation/solidification technology. This approach to on-site remediation is encouraged by the Environment Agency as the way forward in sustainable contaminated land remediation.

Envirobind consists of a cementitious material that is added to the soil on site to stabilise and solidify it, sealing the contaminants into the mix in the process. As a result the contaminants present are no longer mobile and will no longer pose a risk to human health, groundwater or surface water. Envirobind is suitable for the remediation of most pollutants including hydrocarbons and inorganic contaminants such as metals and asbestos, and can be applied to most of the soil types found in Britain. The exact formulae for Envirobind will be designed to deal with the specific cocktails of contaminants identified on each site. In the case of complex contaminant mixtures the formulation will be based on site-specific laboratory trials to ensure optimum results.

The addition of Envirobind reduces the moisture content and increases the density and strength of the mix, thereby creating a high-quality reinstatement material. Soil that might have been taken to landfill can be re-used on site, reducing or eliminating the need to import engineering fill. Any surplus material will qualify for disposal in a lower and thereby cheaper waste category.

The use of Envirobind removes or significantly reduces the need for off-site disposal. Vehicle movements will be reduced. That means no or much lower tipping charges, and less or no landfill tax to pay.

By comparison with conventional on-site remediation techniques including windrowing, Envirobind is a faster process. It will require the one-off application of specialist plant for mixing supplied by METRO, and no time-consuming soil treatment over time. The contaminated soil is excavated and mixed with Envirobind using specialist mixing plant. The mix will rapidly cure to a compactable state, and can then be reinstated.

Using Envirobind avoids delaying your construction project, unlike some other on-site remediation techniques and is suitable for sites of all sizes. This process presents a fast, cost-effective and sustainable solution to ground contamination and cuts your remediation costs as well as your carbon footprint.

Environmental responsibility

In this current climate, there is a greater need to enhance the value of land holdings.  A site that has been remediated will have an increased value as an asset and will be saleable.  A contaminated site held as part of a land bank will continue to fall in value. The withdrawal of the landfill tax exemption and the reduction in landfill capacity means a continuous increase in ‘Dig and Dump’ costs. Dig and Dump is already the most costly and environmentally unsustainable option.


In the UK the Envirobind type of remediation methodology enjoys the support of WRAP (the Waste & Resources Action Programme), a government-funded not-for-profit organisation whose primary aim is to reduce the amount of waste sent to landfill.

Completing the Remediation Package

Remediation Validation Reports from METRO

To complete the rehabilitation of your redevelopment site, METRO, through collaboration with experienced (independent) environmental scientists, will provide comprehensive validation remediation reports as part of the remediation package, and, liaising with local authorities, Environment Agency and other stakeholders, will guide your site through to the final sign-off.
