  • Good evening ladies and gentlemen My name is Tom Cherrett and I am a lecturer in the Transportation Research Group at the university of Southampton, UK.
  • -
  • So the historic city of Winchester has many access issues making it difficult for freight and service vehicles Pedestrianised section of the High Street Access restrictions
  • Narrow streets and limited on-street loading facilities
  • And hence, there is a considerable amount of activity which infringes the loading/unloading regulations Also, the one-way system can suffer in terms of congestion as a result of freight activity
  • -One area of interest is to what extent waste is generated as part of the gate-keeping process and if more of this was done in-store, what could be the impacts on reverse mileage?
  • -Given that a large proportion of commercial waste is compositionally similar to household waste, more efficient collection services could result if the commercial and industrial waste category was integrated with municipal waste which is common practice across the rest of Europe - 3.9 tonnes/fortnight commercial recyclate could be collected on the typical domestic collection vehicle without increasing number of trips to disposal site (report for DfT, 2006) Potential barriers Spare capacity on domestic collection vehicle Spare time on existing rounds All commercial waste/recyclate collected as part of a joint collection has to be separated out prior to treatment to meet legal requirements

    1. 1. Joint domestic/commercial collections for Winchester? The NFDC model applied to a case study in Winchester <ul><li>Tom Cherrett </li></ul><ul><li>University of Southampton </li></ul>
    2. 2. Background <ul><li>Freight study as part of Winchester’s ‘Town Access Plan’ consultation </li></ul><ul><li>Impacts of ‘core goods’ and ‘service’ vehicles in an urban setting – Winchester High Street businesses (n=83, 69%), West Quay Southampton (n=100, 96%) </li></ul>
    3. 3. Work Activity – Winchester & Southampton Business managers surveys Delivery driver surveys Waste contractor surveys Returns management company surveys Understand retail waste and returns management strategies Identify opportunities to reduce transport impacts whilst enhancing material take-back Consolidated take-back, best practice treatment processes
    4. 4. <ul><li>12.7 million tonnes of commercial waste are produced annually. ( Envirowise,GG362 ) </li></ul><ul><li>48% of commercial waste ends up in landfills. </li></ul><ul><li>Over 50% of the commercial waste is being classified as General Mixed. ( Defra ). </li></ul><ul><li>- Paper and Cardboard account for 20% of commercial waste ( Defra ) </li></ul>Retail Waste in the UK

    10. 10. Key findings: Take-back <ul><li>41% stated they did not use any back-loading capacity of their main logistics provider/supplier </li></ul><ul><li>37 vehs/week serving 12 retailers always back-loaded RTN’s </li></ul><ul><li>Service visits to the average business (7.6/week) on top of 5.8 core goods deliveries (13 veh visits/week/business) </li></ul><ul><li>Estimated that for 100 High Street businesses, 245 collections required to collect over 219, 659 litres of residual waste/week (19 contractors) </li></ul><ul><li>139,007 litres of cardboard (131 roll-cage equivalents) could be produced by all High Street businesses per week) – 15 veh trips (18T rigid) </li></ul>
    11. 11. Greener Solutions for take-back <ul><li>Joint domestic/commercial collections? (merge ‘municipal’ and C&I waste categories – directed at SMEs) </li></ul>
    12. 12. Joint domestic/commercial collections for SME’s <ul><li>How could domestic RCV rounds be used to service SME’s? </li></ul><ul><li>Commercial round data for 577 customers around Winchester </li></ul><ul><li>Domestic collection data from 25,586 houses </li></ul><ul><li>Use DPS Logix to estimate: </li></ul><ul><li>Weights of SME waste that could be taken by RCVs </li></ul><ul><li>Impacts on RCV round time and distance </li></ul><ul><li>Reliability during peak generation periods </li></ul>
    13. 13. Greener Solutions for take-back <ul><li>Modelled joint collections reduced vehicle mileage by up to 9.8% </li></ul><ul><li>Joint collection rounds had capacity to take 35.8T trade waste per week (an additional 690 trade bins/sacks, or around 288 additional trade customers per week. </li></ul>
    14. 14. Greener Solutions for take-back <ul><li>Leave ‘core goods deliveries’ alone and address service activity? </li></ul><ul><li>Could retailers employing centralised distribution systems back-load recyclate/returns on behalf of high street neighbours? </li></ul><ul><li>Would 3PL’s/dedicated logistics providers aid take-back logistics by running into out-of-town groupage facilities? </li></ul><ul><li>Would LPs sign up to a back-loading register and be targeted for returns/recyclate removal? </li></ul><ul><li>What could be the benefits of ‘localised’ treatment to reduce the transport footprint? </li></ul><ul><li>Last-mile co-ordination (SMARTFREIGHT project) </li></ul>
