Experience of develping a compost quality assuranca scheme in Ireland

rx3, www.rx3.ie, is a Department of the Environment, Community & Local Government (DECLG) Programme established to help develop markets for recycled material in Ireland to form new products, including compost.
Barriers to market development for compost products in Ireland identified in the past included the lack of a compost quality assurance scheme (CQAS) and a national compost quality standard (CQS) to prove that the process has been independently verified as being bona-fide and the compost is high quality and suitable for the intended purpose. rx3 has an objective to address this issue by working with stakeholders and using existing work.

Cré, the Composting and Anaerobic Digestion Association of Ireland, conducted research that was funded by the Environmental Protection Agency (EPA). This research analysed Irish compost quality databases and proposed appropriate limit values for certain parameters. Cré then developed an industry quality standard for source separated biodegradable waste derived compost, tailored to Irish conditions. This standard proposed limit values for parameters including heavy metals, pathogens, impurities, stability and organic matter. This report “Development of an Industry- Led Quality Standard for Source-Separated Biodegradable Material Derived Compost” was published in 2009. In 2009, rx3 requested the National Standards Authority of Ireland (NSAI) to develop a CQS for source separated biodegradable derived compost. The NSAI used published research that compared Irish compost quality databases with databases and standards from other European countries. Irish Standard 441:2011 was published June 2011. rx3 appointed Certification Europe to develop a CQAS using I.S. 441 specifications. Work started February 2011 and comprises three phases.
• Phase one: initial drafting of the relevant CQAS documentation.
• Phase two: trialling of the draft CQAS at suitable compost facilities.
During this phase a competent auditor audits the facility using the Draft CQAS as criteria and identifies areas for improvement and recommendations. A sitespecific training package and an action programme with defined responsibilities and timelines is developed and presented to the operator. Certification Europe assists the organisation implement recommendations and prepare for pilot certification. The key challenge is balancing CQAS requirements with existing regulatory requirements. Not adding regulatory burden is important for successful uptake of the CQAS, by the composting industry.
• Phase three: operating the CQAS on a pilot basis.
Twenty composting facilities have been recruited, audited and trained by March 2012, representing 69% (288,500 tonnes) of the operational capacity of Irish composting facilities. Results from the trialling phase have highlighted that the majority of producers are well prepared and have documented procedures and processes that support a seamless progression to certification. Furthermore, the feedback from operators has been very positive. Certification Europe has developed a quality mark, to assist in marketing and identifying high quality compost, increasing overall awareness and understanding of quality issues in compost. CQAS I.S. 441 will enter phase three in July 2012, when it will be implemented on a pilot basis, with facilities being certified and certified compost coming onto the market. An awareness programme is being implemented to develop awareness of the scheme in compost users. Following development, the CQAS will be self-funding.

Development of local municipal solid waste management in the Western Transdanubia region of Hungary
© Lehrstuhl für Abfallverwertungstechnik und Abfallwirtschaft der Montanuniversität Leoben (11/2020)
Hungarian municipal solid wastes (MSW) management has developed tremendously over the past 15 years. More than 3,000 landfills and dumps had been closed, just to mention one improvement. However, still, lots of work is necessary to accomplish the EU’s ambitious aim of decreasing landfilling and increasing recycling and composting.

Compost-like material or thermal valorization – impact on MBT Plant economics and environmental aspects – Case studies in Portugal and UK
© Wasteconsult International (5/2015)
The paper focuses on the utilisation of the solid product from the biological Treatment stages of three MBT Plants which treat the organic fraction of MSW by means of wet mechanical pre-treatment units followed by anaerobic digestion. The experiences of two MBT Plants in Portugal (CVO Valorlis and CVO Suldouro) which produce compost-like material are contrasted with the experiences at the MBT Bredbury Parkway (UK) which, by drying the digested solids, produces a RDF with low calorific value for further use in thermal valorisation. The impact of these two different approaches on the operating costs for the treatment of the digested solids as well as the environmental aspects for both valorization paths is discussed.

Post-treatment of Composting Leachate by Photocatalytic Process
© Wasteconsult International (5/2015)
In this study the capability of UV-ZnO photocatalytic process as a post Treatment method for composting leachate was examined at laboratory scale and in batch mode. The effect of some factors such as initial pH, oxidant concentration, light intensity and reaction time on the removal of organic load and color of leachate were investigated. Biological pre-treated leachate samples were collected from the effluent of leachate treatment facility of a composting plant in north of Iran. A Plexiglas column with 110 mm inner diameter and 300 mm height were used to conduct experiments. UVC lamps with different power levels in the range of 8-40W at the centre of the column were used as the source of irradiation. Based on the results of experiments, after 180 minutes of Radiation with 32W UVC lamps in pH 11 and in the presence of 1g.L-1 of slurry ZnO, maximum COD and color removal were achieved to be 57% and 67%, respectively.

Effects of alkaline pretreatment on the anaerobic digestion process of vegetables wastes
© European Compost Network ECN e.V. (6/2012)
Methane is produced by methanogenic bacteria from acetic acid, hydrogen and carbon dioxide and from other substrates of which formic acid and methanol are the most important (Bouallagui et al., 2005) during the anaerobic digestion of organic biomass. The objectives of this study consisted in setting up laboratory–scale biochemical methane potential (BMP) assay digesters at mesophilic conditions to assess the effectiveness of alkaline (NaOH) pretreatment in improving the anaerobic digestion process for biogas production from mixed vegetable wastes.

Digestate and compost quality - case studies at anaerobic disgestion plants with the BTA Process
© European Compost Network ECN e.V. (6/2012)
The key for the successful anaerobic digestion of biowaste and/or municipal solid waste is an efficient removal of the impurities before the digestion step. This is not only indispensable for the reliability of the process and therefore the plant availability, but furthermore for the quality of the produced digestate or final compost. With the existing developments within the EU, the quality of the digestate / compost has become a focus of attention. Further Authors: P. Bolzano - Biotec Sistemi s.r.l. J. Del’haye - IVVO
