When product status is not enough – the development of a UK Renewable Fertilizer Matrix
The UK standardised its approaches to ‘end of waste’ for compost in 2007, and digestate in 2009. Both are now well-established, covering around 50% of the UK’s 3.5 million tonnes of compost and 20% of the 1.4 million tonnes of digestate that were produced in 2012.
These end of waste approaches require that materials are independently certified to a baseline quality specification (Publically Available Specification (PAS) 100 for compost, PAS 110 for digestate), which includes thresholds on parameters such as potentially toxic elements, physical contaminants and indicator pathogens. However, despite the availability of these specifications – and their endorsement by the UK’s environmental regulators – the UK food chain has expressed a number of reservations around the quality and safety of compost and digestate. In some cases, this has led to compost and digestate use being restricted by farm assurance schemes.
Working with these assurance schemes, as well as food safety authorities and retail representatives, WRAP has supported the development of an evidence-based Renewable Fertiliser Matrix. It incorporates specific harvest and cropping intervals for compost and digestate against a range of standardised cropping categories, which align with categories used by the extremely influential Red Tractor Farm Assurance scheme.
This presentation will outline the wide range of concerns expressed by the UK food chain, the evidence gathered to counter them, and the future of the Renewable Fertiliser Matrix.

Landfill Mining: Entwicklung eines gesamtheitlichen Bewertungsverfahrens
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2016)
Aufgrund der global sehr ungleichmäßig verteilten Primärrohstoffe, der wirtschaftlich oft nicht rentablen Erschließung neuer Lagerstätten sowie der Intention der Europäischen Union den Verbrauch an Primärrohstoffen zu reduzieren und die Rohstoffeffizienz zu verbessern (EC 2010), sollen neben dem klassischen Bergbau nun auch andere Rohstoffquellen genutzt werden. Eine effiziente Nutzung von Sekundärroh- und -brennstoffen aus Landfill Mining Projekten kann in diesem Zusammenhang einen wichtigen Beitrag zu einer nachhaltigen Ressourcenwirtschaft in Europa liefern. Aus diesem Grund untersuchte das Projekt „LAMIS - Landfill Mining Österreich“ Deponien, die einen hohen Anteil an nutzbaren Wertstoffen im Vergleich zur gesamten abgelagerten Abfallmenge aufweisen, mit dem Ziel Sekundärrohstoffe aus dem Deponiematerial rückzugewinnen.
Recycling per Mausklick – Der Beitrag des Internet zum Urban Mining
© IWARU, FH Münster (2/2015)
Rohstoffe sind knapp. Das Internet bietet die Chance ausgediente Produkte mit chirurgischer Präzision aus dem Markt zu nehmen und einer hochwertigen Verwertung zuzuführen. Diesem, vom Autor als Recy-Commerce bezeichneten Geschäftsmodell, stehen häufig rechtliche Rahmenbedingungen entgegen. Seine Forderung: Qualifizierten Unternehmen soll es erlaubt werden Abfälle aus privaten Haushaltungen anzukaufen und zu verwerten.
Optical Sorting for the Recovery of Glass from WIP Slags – Pilot Plant in Bratislava –

Today, the sensor-based detection and separation of recyclable materials is an important component of waste processing and the recovery of raw materials worldwide.
Cullet especially is an important secondary raw material and indispensable for economic and competitive hollow glass production. The more broken glass material is put into the melt, the less energy is required and fewer additives have to be used. Modern furnace designs and strict exhaust values are based on using up to eighty percent of glass fraction. With such a high proportion of glass content, the cullet quality should be appropriately high so that the melting chemistry is not adversely influenced and so as to avoid malfunctions or even hazards in the production process.
Bioresource utilization chains – Efficiency of substantial and energetic utilization Options on the example of food residues and grass cuttings in a district of Hamburg
© European Compost Network ECN e.V. (6/2014)
During the chain from an agricultural bioresource to a food product, by-products and residues are generated. The majority of the residues are handled within urban waste and waste water management structures; the contained valuables regarding the energetic content and nutrients such as N and P are actually inefficiently or not utilized. The mass flows from primary agricultural bioresources to food consumption and the whereabouts of the residues will be analyzed. Similarly the green waste sector is studied on the example of lawn cuttings.
Define waste criteria for the production of high quality compost
© European Compost Network ECN e.V. (6/2014)
The Waste Framework Directive 2000/98 (WFD) contains specific provisions to define end-of-waste criteria (EWC). The objective of EWC is to remove the administrative loads of waste legislation for safe and high-quality waste materials, thereby facilitating recycling. The objective is achieved by requiring high material quality of recyclables, promoting product standardisation and quality assurance, and improving harmonisation and legal certainty in the recyclable material markets.
