Waste as a resource - Pathway to a Resilient Future for Dorset - Workshop Presentation - Bob Lisney

  1. 1. Waste as a resource
  2. 2. 11.1 Waste and the circular economy
  3. 3. The test model concept has a number of interrelated elements:  it is spatially-explicit  it models materials (“resources”)  it models conversions (“processes”) – both natural and synthetic  it includes business models, economics and behaviour 1.1 The Ecological Sequestration Trust (TEST) circular economy model
  4. 4. Overall ambition:  identify nature, quantity, location and destination of wastes  combining spatial and technological models identifies local opportunities.  needs knowledge of potential local “user” industries  material types, demands, locations, technology needs  identify piloting opportunities  locations  stakeholders/partners  business and funding models 1.1 Application to Dorset
  5. 5. 1. Understanding of current and recent historical data on all wastes sub- streams 2. Understand compositional data for the sub-streams 3. Geophysical understanding of Dorset Managed or preserved land, degree of urbanisation Brief overall description of the terrain. 4. Socio-economic understanding of Dorset Population density, economic sectors (input-output data if applicable), Uptake routes for recovered materials and energy, e.g. markets Opportunities for industrial ecology / symbiosis initiatives. 1.1 General approach (part 1) Digestate granulate
  6. 6. 6. Results The analysis includes a narrowing down of the technical opportunities appropriate to the local resource. Indication of the options that can address Dorset’s sustainability objectives relating to greenhouse gas, cost, recovery rates, secondary impacts or substitution effects, resource efficiency, and, finally, energy, material and food security. 1.1 General approach (part 2) 5. Available Infrastructure Current waste management installations (performance and capacity) Current recycling and material re-processing facilities and their location Potential demand for improved recovered materials Plus collect similar high-relevance data for neighbouring areas CO2  CH4
  7. 7. 1.1 Case study: Increasing value of biogenic waste The region does not send much biogenic waste to landfill (although there is no breakdown of MSW which will include food waste and water waste may include sludge): 190 67 11805 5351 105 2437 185 154265 454 4166 90156 AGRICULTURE AND FOOD PROCESSING WASTES CHEMICAL SURFACE TREATMENT AND COATING OF METALS WASTE CONSTRUCTION AND DEMOLITION WASTES CONSTRUCTION AND DEMOLITION WASTES FURNITURE, PAPER AND CARDBOARD MANUFACTURING WASTES HUMAN AND ANIMAL HEALTH CARE WASTE MINE AND QUARRY WASTES MUNICIPAL WASTES SHAPING AND PHYSICAL TREATMENT OF METALS AND PLASTICS THERMAL PROCESSES WASTE WASTE ABND WATER TREATMENT WASTES
  8. 8. This includes Green waste : current estimate 0.1m tonnes per annum (tpa) Biogenic fraction of MSW and C&I waste 0.5m tpa of C&I in region, estimate 12% biogenic 0.4m tpa of MSW, estimate 30% biogenic Agricultural waste : current estimate 0.1m tpa Wastewater treatment solids : current estimate 0.1m tpa Total circa 400,000 tpa Note that the organic fraction of waste in the region is estimated at around 180ktpa but this excludes agricultural. A separate analysis gives a figure of 600,000 tpa as a capacity requirement for non-inert waste. Current destinations 7 facilities : 4 x Anaerobic Digestion (AD) and 3 x composting Total capacity of about 150,000 tpa (approx 115 kpta composting) Value generation estimate: composting: £60,000 pa AD: £4,000,000 pa Unknown : value generation per tonne processed = 0 Total current value-added = £4.06m [estimate] 1.1 Biogenic waste – current situation
  9. 9. Examples of opportunities arising from more sophisticated approach: Intercept waste at source and optimize end use by type  segregation of all bakery waste and use for animal feed: value > £100/t  hydrolysis of green waste and conversion to industrial biotech and chemical feedstock: value added ~ £200/t  gasification of sludge, waste wood etc and conversion through fermentation (e.g. Lanzatec process) : value added ~ £200/t  Maximise the benefit of AD through integrated nutrient cycling and grid integration Potential future value-added > £40m pa Tenfold increase through integrated analysis and new technology! Upcycling of biogenic waste – systemic opportunities
  10. 10. Resource recovery/upcycling should be designed in a holistic way, so that the product, processes and chain are optimised for a circular economy system, rather than the current approach to bolting-on recycling processes. We are working on fundamental techniques for supply chain design and applying them to diverse applications, including fluorescent lamps in Korea. The diagrams alongside show our redesign of a fluorescent lamp recycling network; the optimised network has a 60% reduction in transport energy and emissions. Benefit of spatial approach : Korean example 1 2 4 5 63 7 8 109 11 12 1413 15 16 17 18 2019 21 22 23 24 2625 27 28 29 30 3231 33 34 35 36 3837 39 40 41 42 4443 45 46 47 48 5049 51 52 53 54 1 7 13 19 25 31 37 43 49 Existing network O 1 2 4 5 63 7 8 109 11 12 1413 15 16 17 18 2019 21 22 23 24 2625 27 28 29 30 3231 33 34 35 36 3837 39 40 41 42 4443 45 46 47 48 5049 51 52 53 54 1 2 4 5 63 7 8 109 11 12 1413 15 16 17 18 2019 21 22 23 24 2625 27 28 29 30 3231 33 34 35 36 3837 39 40 41 42 4443 45 46 47 48 5049 51 52 53 54 Existing network Optimised network
  11. 11. Case study: green waste conversion – integrated bio refinery The flexible, modular biorefinery Variety of raw materials preprocessing CO2 sink IB chemical thermal Biochar to land Variety of products Modular and flexible; can adapt to changing feedstocks over time Pilot in Aberystwyth (Beacon project) ..... Example would be MSW → RDF → pyrolysis oil → upgraded pyrolysis oil Could be utilised in Dorset
  12. 12. 11.1 Furniture Refurbishment 90,156 tonnes of furniture, paper, cardboard and manufacturing waste per year Sofas, fridges, cookers, microwaves, dining tables, washing machines Bulked up in Dorset and sent to other authorities to be treated / turned into new products Re-use networks offer affordable furniture – successful schemes set up by Hampshire County Council and others Community social enterprise companies such as TRACO – The Recycled Assets Company
  13. 13. 11.1 Furniture Refurbishment Potential market:  Council tax records indicate 2000 properties occupied by students in Bournemouth  Large numbers of homes of multiple occupancy (HMOs), notably Boscombe East and Winton in Bournemouth  Bournemouth estimated increase in unemployment from 2007-2010 Poor households seek accommodation in lower priced areas such Blandford Forum and parts of Bournemouth 26% households cannot afford houses in current market without subsidies – esp. Bournemouth, lone parents
  14. 14. Adding value to waste products is an idea with great currency However it is hindered by: -Lack of data -Lack of clear business models -Need to synchronise system/infrastructure and markets TEST has been set up based on a recognition of these issues -Spatially-, temporally- and technologically-rich data sets will be included in the platform -Geolocalisation and data fusion will keep the system up to date -Economic and activity models can be used to explore different business models -Benefits can be quantified 1.1 Summary
