Calder Holds A Leading Position In The Domestic remediation Market.
Calder Environmental Ltd was established to provide a sustainable solution to assist with the recovery of contaminated soils and construction & demolition materials which exist in abundance on brownfield sites across the UK.
Utilising best available technology and operating from North Dean Waste Recovery Facility under Environment Agency Permit Number EPR/NP3329SN, Calder Environmental offers remediation solutions specific to asbestos-containing soils & aggregate along with the remediation of waste soils containing elevated levels of hydrocarbon.
The innovative methods of treatment as opposed to the common approach of sending hazardous materials to landfill, offers both environmental and commercial benefits to all stakeholders involved in a contaminated site. With landfill tax increases and an ever decreasing capacity to send materials to landfill, the implementation of circular economy principles make effective soil and materials reuse an increasingly important approach.
Ultimately the Calder Environmental recovery process allows treated material to be classified as a product as opposed to a waste, allowing all parties to benefit from the reclassification.
The facility also has the ability to deal with other associated hazards such as the treatment of soils impacted with invasive species such as Japanese knotweed or material which has general wastes such as metals and plastics contained within.
Soil and aggregate recovery
Tackling a National Challenge
Asbestos-contaminated soil is a widespread issue across the UK, especially on brownfield sites affected by past construction and demolition. Historical use of asbestos and poor waste practices have left many sites with hidden hazards, delaying redevelopment and driving up costs. Addressing this challenge is key to unlocking valuable land.
Legacy Waste, Lasting Impact
Asbestos fibres are often embedded in soil and rubble, making removal complex and expensive. When disturbed, they pose health and environmental risks. Proper separation and treatment are essential to safely prepare sites for redevelopment without escalating project costs.
Supporting Brownfield Redevelopment
Government policy encourages the reuse of brownfield land to ease housing and infrastructure pressure. Calder Environmental supports this by offering practical, sustainable remediation services that help developers meet targets while reducing environmental and financial burdens.
Smarter Remediation, Safer Outcomes
Our specialised process separates asbestos-containing materials from soil and waste, reducing contamination levels. This makes the treated material safe for non-hazardous disposal or reuse, cutting landfill costs and improving site turnaround times.
Turning Waste into Resource
Instead of sending contaminated material to hazardous landfill, we reclassify treated soil for safe reuse. This approach supports the circular economy, minimises environmental impact, and helps transform waste into a resource for future development.
Bio-remediation
Cleaning Contaminated Soils, Naturally
Hydrocarbon contamination is a common issue on brownfield sites, often left behind by historic industrial activity. Calder Environmental offers a sustainable solution through bioremediation, a proven method to restore polluted soils and support site regeneration.
A Legacy of Hidden Hazards
Many brownfield developments still carry the impact of past industrial use, including elevated hydrocarbon levels in soil. These contaminants, though invisible, can delay projects and pose environmental and regulatory challenges if not properly addressed.
Advanced Physico-Chemical Treatment
Calder Environmental uses a physico-chemical approach to treat hydrocarbon-affected soils. By applying micro-organisms, tailored nutrients, and enhanced oxygen levels, we trigger the natural breakdown of hydrocarbon compounds within the soil.
Safe, Sustainable, and Effective
Our bioremediation process mimics nature’s own clean-up method, eliminating hazardous substances without the need for aggressive chemical treatments or excessive waste disposal. It's an environmentally friendly solution with measurable impact.
Turning Waste into Restoration Material
Once treated, the soil is no longer classed as hazardous and can be safely reused as a restoration material. This not only reduces landfill reliance but also helps developers close the loop on contaminated land remediation.
