Sound Science for Environmental Services

Increasing controls on the use of waste products on agricultural land means that analysis of the waste product itself, and the land to which it is applied, is critical in preparing the documentation required to allow the recycling of waste to land.

By using manures and slurry on agricultural land, fertiliser costs can be reduced and farm profitability increased. Valuable organic matter will also be added to the soil. However to achieve this it is essential that the content of these wastes is understood. 

Compost and digestate help to improve soil structure and enrich the nutrient content of the soil. NRM, as a Organics Recycling Group (ORG) approved laboratory, can provide analysis of composted waste under the BSI PAS 100 Certification Scheme. NRM is also an REA - Biofertiliser Certification Scheme certified laboratory for PAS 110 analysis of whole digestate, separated liquor and separated fibre derived from the anaerobic digestion of source-segregated biodegradable materials.

NRM offers analysis of a wide range of waste products including: biosolids; food and drink residues; animal by-products; canal dredging; water treatment sludge; lime; green waste; paper sludge and compost. In addition, NRM can analyse the land to which the waste is being applied for the major nutrients, trace elements, potentially toxic elements and additional contaminants, if required.

In summary:

  • Provision of analysis for all areas of the waste sector;
  • BSI PAS 100 Composting Association approved testing laboratory;
  • Bespoke reports including recommendations for Benefit Statements;
  • Analysis helps reduce the risk of pollution which may arise from the application of waste and compost to land;
  • Analysis for Acceptance of waste material to landfill;
  • Analysis services for waste processing plants.

Key Environmental Analysis & Tests

Publicly Available Specifications

Millions of tonnes of waste are landfilled every year in the UK. Efforts are being made to increase awareness in the value of waste as either an end product or a means of producing energy.

NRM currently offers testing relevant to four publicly available specifications.

PAS 109

Waste plasterboard can readily be recycled into its constituent parts – gypsum and paper. The recycled gypsum has use in a variety of applications which currently use natural or synthetic gypsum. These include use as a  raw material in the manufacture of new gypsum-based products or in the manufacture of cement as well as a soil treatment agent for agricultural benefit. This PAS provides a standard for recyclers to produce a quality assured recycled gypsum of consistent and defined quality.

PAS 100

Any biodegradable wastes that are diverted from landfill to undergo a composting process of which the end product is of sufficient quality to supply a diverse market is a significant benefit to the environment. Compost can be used as soil improvers, mulches, partial substrates in growing media and as a significant ingredient in manufactured topsoils and turf dressings. The PAS100 specifies amongst other things a minimum quality to ensure they are fit for purpose.

PAS 110

Anaerobic Digestion (AD) is an important technology of source segregated biowastes. The biogas they produce can be converted into energy. The whole digestate, separated liquor and fibre outputs that AD systems produce can have significant fertilizer value and return good organic matter to soil.

PAS 111

Waste wood arises in a multitude of forms, and a lack of consistency in the way waste wood is accepted, graded and processed is a barrier to the industry’s objective of increased recovery rates. End users need confidence in the uniformity and quality of recovered wood, while waste wood re-processors need to know how to design their operations to meet the requirements of their customers and the regulators. PAS111 seeks to establish a minimum set of criteria and processing requirements for material to be deemed to be suitable
for onward sale, albeit as a waste derived material.

Waste to Land

Under the waste to land regulations (see the Code of Practice for Agricultural Use of Sewage Sludge) all applications of sludge and waste to land must be approved by the Environment Agency. It always needs to be demonstrated that there is a nutrient demand for the product and that the product will not cause an excessive accumulation / toxicity risk. In order to do this a certificate of soil analysis (to prove requirement) and a certificate of sludge material analysis will be required. NRM are specialists in this kind of analysis.
