Stimulating new ideas at the industries’ most talked about event
From incineration to digestion over 10 years
Jolly, M.1, Taylor, T.2, 1 Black & Veatch, 2 Yorkshire Water, UK
Yorkshire Water have a plan to close down four sewage sludge incinerators that have been the main disposal route for sludge produced in the Yorkshire area since the 1990s. The incinerators are being replaced by thermal hydrolysis and mesophilic anaerobic digestion (MAD). Black & Veatch are currently working on a scheme to build a new sludge treatment facility at Knostrop in Leeds to treat up to a maximum of 48 000tds/year of sewage sludge. This involves MAD followed by lime addition and liquor treatment by the DEMON process.
Panel debate: Biosolids: has land application had its day?
Led by Dr David Tompkins, Aqua Enviro and including:
- John Williams, ADAS,
- Mike King, Geneco
- Prof Stephen Smith, Imperial College
Biosolids provides a range of beneficial properties when recycled to land – supplying organic matter and nutrients, particularly phosphorus. This market is well-established, farmers see real benefit from using biosolids, and the Biosolids Assurance Scheme provides confidence around the quality, consistency and safety of the product. Although these benefits are tangible, water companies are increasingly viewing sludges as an asset that can add value to their own businesses. This could mean using sludges as substrates for energy recovery through pyrolysis, or as feedstocks for biorefining. At the same time, public awareness of issues such as anti-microbial resistance and micro-plastics could start to impact on land-based markets for biosolids. Our panel of experts will explore these themes and more as we ask whether land application has had its day.
New Markets & Materials
End-of-Waste Seminar with RRfW
Changing the regulatory status of your material from waste to product can be an essential first step in market acceptance. This facilitated session will bring together experts to discuss previous experience of the End-of-Waste process and to look ahead at what the future might bring.
This is your opportunity to hear first-hand how companies have taken materials through the end of waste process, how the EU fertiliser regulations may change the playing field, and how the process is driven by data.
• Clive Humphreys, Environment Agency: A regulator’s perspective
• Esther Kiddle, TK Associates: A legal perspective
• Justyna Staff, REAL: A standard approach: End of Waste for compost and digestate
• Ostara -speaker to be confirmed: Achieving a bespoke End of Waste position, and the importance of data to support your case
• Anne Velenturf, Leeds University: Incentivising the wrong thing: when illegal export is more lucrative than legal recycling
• Kristy Blakeborough-Wesson, Secanim: EU Fertiliser Regulations, what do they mean for future end of waste approaches?
