The 4R Group has developed bespoke specifications for several large waste companies across the UK, each uniquely designed to restore a range of different soils and geological materials in situ.
4R Group has a dedicated team for sourcing and securing suitable land bank, throughout the UK, within viable distances of material production facilities. Our consultants are FACTS and WAMITAB qualified and will apply and obtain the environmental permits required to carry out the recycling activities.
If required, 4R Group is also able to deploy its own mobile plant permits and staff technical competencies at an unlimited number of sites in England and Wales. What’s going to happen in the future?Growing numbers of treatment facilities means volumes of organic rich materials which need to be recycled, i.
Pressure on available land bank, eligible to receive these materials is increasing; this in turn intensifies the inevitable competition between waste recyclers, with a knock on effect on site gate fees which continue to rise as increasing outputs flood the market. With mounting site and compliance costs it is even more important that treated waste outputs are produced to the highest possible standards, in order to facilitate their recovery to land.
If done correctly, this should expand usability to include agricultural applications, development of which is ongoing.

Successful recovery of these valuable resources is beneficial to the producers and the landowners, but most importantly it diverts essential nutrients and organic matter from landfill, giving it back to our precious soils. Langton Colliery Spoil Case StudyJune 2013 - March 2014Utilising waste materials to restore brownfield land for long-term environmental gainThe former Langton Colliery Spoil is highly visible to travellers in both directions on the M1 motorway just south of junction 28 in Nottinghamshire.
Having been dug over to remove coal 4R Recycling was asked to restore the soils on site turning it from black to green. If you’ve got the spoil, we can make the soilThe tip was washed by ReCycoal Ltd over a three year period which involved moving the whole tip and re-shaping it.
With little soil originally on the site 4R Recycling was asked to reduce background acidity, improve organic matter and nutrient levels, then seed the former tip in accordance with tight planning requirements to create both agricultural and amenity land. Satisfying the environment, local council, environment agency, local residents and the site ownerWorking alongside ReCycoal Ltd our consultancy team helped draw up a restoration scheme that used inorganic and organic “waste” materials that satisfied the requirements of the county council to improve the site.
Our team applied for a deployment to their Environmental Permit from the Environment Agency to allow the use of the specified “waste” materials in the project. This deployment was granted and the importation of materials commenced using a variety of different lorry types, including over 23,000 tonnes of materials that were stockpiled, spread and incorporated into the existing surface in different areas depending upon the end use.
Following the completion of application heavy duty agricultural equipment was deployed to plough, create a seed bed and sow the various seed mixes required.

Croft Quarry Case StudyJuly 2014 - September 2015Over many decades Croft Quarry has created a visible scar on the landscape of Leicestershire. The 4R team carried out the final stage of the restoration of the land, covering the top of the dome created by quarry spoil and finally completing the transformation of this area.
The land is now suitable for amenity and leisure usesThe project not only restored a disused section of the quarry, but recycled 1,000s of tonnes of organic solids which would otherwise have been tricky to dispose of. Being paid a fee to recycle this material made the restoration cheaper for the landowner - big benefits all round!The project: Phase 3 restoration of Croft Quarry - capping offAfter hundreds of years of quarrying at Croft in Leicestershire, the beginning of the quarry’s restoration began more than a decade ago.
In 2014 our team imported 1,000’s of tonnes of sewage sludge to enrich the top of the spoil heap, eventually making it suitable for cultivating seeding in March 2015.
Members of the 4R team have been involved with phases 1 and 2 of the recent restoration as employees of other organisations and we were proud to be asked to complete the job Environmental, Technical, and.

The brief A steep stack had been created by centuries of quarrying. The land was essentially inert, with no nutrients on which plants could feed.
This meant the now disused quarry continued to be a blot on the landscape despite two previous phases of restoration covering other areas of the site. We were asked by the landowner to:Cap off the top of the spoil tip, improving organic matter and nutrient levelsEnsure compliance with all local authority, Environment Agency and other regulatory authoritiesSeed the siteHow we did it Our consultancy team worked with the client to agree a plan of importing organic materials to enrich the inert land.
Once the plan was approved our team:sourced and imported 1,000’s of tonnes of sewage sludge per hectare with which to enrich the inert landscapestockpiled the sludge at the bottom of the stack (it was too steep for lorries) and used tractors to take it to the topspread the sludge on top of the spoil heap, rather than mixing with the existing materialsmanaged the odour emitted when spreading the organic material using mobile de-odourising unitsleft the sludge to dry out and shrink before returning to cultivate and seed it a few months laterBenefits The site owners completed the final restoration of their site with little cost because we have relationships with water companies which need to constantly recycle their sewage sludge. Our innovative use of sewage sludge not suitable for use on other types of land to enrich inert materials means the site is now suitable for woodland planting or amenity use and is no longer a scar on the Leicestershire landscape.

BEFORE AFTERWorking with the landowner our consultancy team drew up a restoration scheme that used inorganic and organic “waste” materials, to create a substitute soil that satisfied the requirements of the regulators and improved the site.
We carried out all the regulatory work, to allow the use of the specified “waste” materials in the project. A total of 25,000 tonnes of material was used to create the substitute soil, which was incorporated into the surface of the site.
We paid the land owner a total royalty of £75,000 for the materials brought onto site. Showcasing our expertise in the restoration of brownfield sitesWe covered all the regulatory costs and all restoration works were completed at no cost to the land owner.

4R Environmental Consultants is working with a number of small Island Government Departments in the assessment of compliance with respect to EU waste treatment legislation, as well as marketing the resulting products for land benefit to farmers, horticulturalists and wider land based industries. Marketing of the products for land recycling is a fundamental issue for small islands, where the sea is both a physical and financial barrier for wider reuse of materials.
On each island we engage with the majority of farmers, crop and product buying groups, plus key customers to assess their needs and restrictions on use of ‘waste’ materials for crop and animal production. This is doubly important where products have Protected Designation of Origin (PDO) status, which must be safeguarded at all costs.
Each individual Island Government understands the requirements for a closed loop waste treatment and recycling service, on their island. They can also see where operations may need improving, according to treatment and recycling compliance, customer demands plus end user restrictions.
Why 4R Environmental Consultants?With a range of in-house technical and operational experience in all areas of waste treatment and recycling, plus an understanding of soil science linked to end market requirements, we are uniquely placed to carry out specialist advice and add value in many areas. Our in depth understanding of the environment and technical aspects of recycling materials for land benefit gives us considerable advantages over other consultancy based organisations.
Particularly when dealing with “waste” producers and land managers who value the use of bulky organic and lime based soil conditioning materials on their land.

This was part of a wider cost-effective and environmentally beneficial solution to treat and recycle contaminated dredging which unlocked this £1. Our technical team, which includes some of the UK’s most experienced soil scientists, was brought in to assess the quality and potential land recycling options for the dredgings, based on in-situ core samples taken from the Marina. Analysis demonstrated that the dredgings had low levels of metals and good soil properties making them an ideal material for restoring local china clay quarries.
This extensive piece of work required us to hold wide-ranging consultations with a number of government departments including the Environment Agency, Natural England, Marine and Fisheries Authority. This was in respect to the potential for Tributyl Tin, a historic component of marine paints often found to be present in marine dredgings, and the potential effects of this compound in the terrestrial environment.
4R Environmental Consultants, with our knowledge and expertise in assessing the risks of organic compound contaminants in soil and water, ensured that safe recycling of the marine dredgings could be demonstrated. As a result, the required agreements to use the dredged material for soil creation were authorised by the Environment Agency.
Working alongside a specialist dredging contractor to manage the 32,000+ tonnes of contaminated sediment from the Falmouth Marina, we demonstrated our ability to recycle difficult waste materials into valuable products through specialist knowledge and practical solutions. Pete Bradshaw, Managing Director of Premier Marinas said: “We just knew there had to be a better solution than landfill – and anyway, landfill tax would have meant that the project was not viable.
4R Environmental Consultants was able to find a better solution, both environmentally and economically.

”As well as the initial consultancy, 4R Group was also responsible for transportation throughout the project - from the marina, to the recycling of the dredgings for use in restoring local china clay quarries. Dr Paul Gibbs, Director of Consultancy for 4R Environmental Consultants, says, “We were delighted to be able to provide such a beneficial solution which helped both the local marine and land environments and closed the recycling loop by making good use of a material that would otherwise have ended up in landfill.
”The whole dredging project increased the size and capability of Falmouth Marina providing wider employment and tourism benefits in the South West region, whilst the recycling of the product assisted in the restoration of old China Clay sites creating natural flora and fauna on previously barren sites.
