Biowaste Management in Europe Results of a Pre-feasibility report for a facility for organic waste recycling in South Backa Waste Management District - Serbia Marco Ricci - Jürgensen Altereko sas on behalf Abt associates About myself • 20 years of experience in planning MSW management, designing and up¬grading of collection and transport schemes, assessing recycling facilities (focus on composting), planning comunication and participation initiatives, chairing multi-linguistic, multi-tasking working groups or projects. • 15 year foreign working experience as consulting expert focusing on issues related to solid waste management. Extensive consultancy experience in the Solid Waste Sector – on Strategy and Policy, Fees&Taxes, Separate collection schemes - , both in ´advanced´ and ´low to middle income’ countries in Europe, Latin America and Asia. • 10 years experience cooperating with international organisation/agencies (as ECN-European Compost Network, ACRR, EEA- European Environment Agency, Sweepnet-GIZ, SCOW). About myself About myself CIC Italian Composting and Biogas Association Senior Expert www.compost.it ISWA International Solid Waste Association Chair of the Working Group on Biological Treatment of Waste www.iswa.org Ecomondo International Fair Ambassador en.ecomondo.com Activities (outside Italy) Bulgaria Czech Republic Slovak Republic UK Spain Tunisia/Sweep-Net Brazil Cambodia Chile Overview • What is biowaste? • Biological treatment options • From City Assessment to Pre-feasibility investigations • South Backa WMR – scenarios for biowaste recycling • Feasibility assessment – OrganECS • Economical drivers What is biowaste? • In Europe, biowaste is strictly defined – Garden & park waste – Food & kitchen waste • Other wastes can also be treated through biological treatment = Biodegradable waste – Animal manures – Agricultural residues – Sewage sludge – Some paper, card and biodegradable plastics Sources of biodegradable waste Hotels Street Factories sweepings Sources Restaurants Markets & cafes Farms Homes The workplan for SB-WMR • to elaborate two scenarios for biowaste processing • basic assessment - from the technical and economic point of view - of the suitability of different organic waste treatment option • actions to promote the off-take of the products resulting from the recycling of organic waste Ref Activity 3 - Task 1 Treatment approaches Biodegradable Wastes Product manufacturing Waste pre- process treatment Quality products Stabilised biowaste for for sale landfill or incineration 10 What is biological treatment? Natural processes 3 main techniques • Treating biodegradable wastes – Using micro-organisms – Natural processes Anaerobic Composting • To create products digestion (AD) • To pre-treat wastes before disposal • Three main techniques Mechanical Biological – Overlap between them treatment (MBT) Comparison of Composting and AD Factor Composting AD Plant capacity Scalable (small, medium, Only Medium to Large large) Tecnology and process Simple More complex Need of working surface Higher Lower Specific investment cost Lower Higher (need of incentives) (i.e. €/t capacity) Output (recycling) Solid product Liquid product 12 The choice of a specific technology for recycling organic waste • will depend on the absolute amounts of OFMSW produced in a specific municipality or waste management region, • on the relative availability of the two main “feedstock” of organic waste (i.e. FW and GW and others).
