Project Description

In Situ Remediation for Contaminated Sites

Project period: 05/2013 - 11/2014

Up until a few years ago, the established approach to site remediation in Germany was to excavate contaminated soils, transport them to a remote treatment plant, and process the contaminated soil using energy or water intensive physical process systems. As a consequence,
there has been little experience with the full scale application of ‚Äúin place‚ÄĚ remediation¬†technologies in Germany. This collaborative project entailed the proof of concept and pilot¬†demonstration of environmental fracturing for the in situ remediation of contaminated sites in

Toterra Ltd. (Frac Rite Environmental Ltd.)

Location: Edmonton, Canada
Founded: 1995
Products: Environmental remediation/fracturing

Toterra provides advanced in situ treatment of contaminants¬†using sustainable remediation technologies that minimize¬†site disruption while maximizing contaminant treatment.¬†Treatment of contaminated soil and groundwater is achieved¬†‚Äúin place‚ÄĚ and sustainably, in that contaminants are converted¬†to harmless end products. ¬†nvironmental fracturing is an¬†adaptation and modification of the hydraulic fracturing¬†used in the oil and gas industry. Using these technologies¬†modified from the Petroleum, Geotechnical, and Water¬†Treatment Industries, Toterra has provided site remediation¬†services across North America, as well as in Europe and Asia.¬†By converting contaminants to harmless end products, as¬†compared with merely transferring contaminated soils to¬†landfills, environmental fracturing fits into the category of a¬†clean, sustainable, small footprint, and low energy demand¬†environmental technology.

HPC is a leading engineering enterprise in the environmental sector. With worldwide operations, the company is committed to projects in the fields of land recycling, environmental consultancy and infrastructure planning. Examples of projects that were successfully completed range from disposal consultancy to land recycling on contaminated sites, following demolition or mine closures. In 2001, HPC AG set up
a new branch for research and development through close cooperation with partners, universities and research centres.
