    "description": "The Government's collection and packaging reforms represent the biggest change to the UK's waste and recycling sector for c.25 years. Simpler Recycling aims to make it easier for households and businesses to recycle, including making provisions by 31 March 2027 for all local authorities in England to collect plastic bags and wrapping (flexibles) for recycling from all households.\nThe FlexFlats project aims to understand how local authorities can provide an efficient and effective flexibles collection service to residents who live in purpose-built flats and share bins (communal bins).\nThe pilots will be carried out in partnership with three London local authorities with five pilot sites (blocks) in each. The local authorities are:\n•\tLondon borough of Bexley (twin-stream dry recycling service)\n•\tLondon borough of Lewisham (comingled dry recycling service)\n•\tRoyal Borough of Kensington and Chelsea (commingled dry recycling service)\nThe pilot will trial a range of methods for flexibles plastics collection in 15 blocks of flats across the three boroughs. Each block will have a minimum of 25 households and will have a residual waste and dry recycling collection service already in place.\nA range of in-home solutions will be piloted. Flexibles sorted in the home will then be collected externally in either the usual dry recycling bin or a separate flexibles bin in the communal bin area - it is anticipated that separate flexibles bins will be no larger than 240l.\nPilots are still being finalised but are likely to include the following:\nIn-home options\tExternal infrastructure options*\n1\tNo home separation - resident behaves as now (control)\tUsual recycling bin\n2\tIn-home separation using residents own bags\tStandard wheeled bin (lined) /\nLid-in-lid bin (lined) /\nSack holder\n3\tIn-home separation using rolls of bags delivered by the local authority\tUsual recycling bin (co-mingled) /\nLid-in-lid bin (lined) /\nSack holder\n4\tIn-home separation using provided storage caddy (non-compaction), with residents using own bags \tStandard wheeled bin (lined) /\nLid-in-lid bin (lined) /\nSack holder\n*External options are being finalised with local authorities, and depend on local factors such as available space and collection and sorting methodology.\nBlocks will have a weekly collection frequency of residual waste and dry recycling, as a minimum.\nThe pilots are scheduled to go live in late September 2026, with baseline monitoring taking place prior (including WCA).  Pilots will run for 3.5 months, running until mid-January 2027, with post-monitoring taking place upon project close.\nThe following project deliverables will be undertaken by the succesful bidder:\n•\tTwo phase waste composition analysis to be undertaken for waste and recycling from all properties at up to 15 pilot sites situated across 15 housing estates/blocks within three London boroughs (five within each borough), using one or more sort sites provided by the local authorities.\nPhase 1: Pre-pilot WCA - to be undertaken between 7th - 26th September 2026 before interventions are introduced\nPhase 2: Post-pilot WCA - to be undertaken late January/early February 2027 to assess impact of interventions\n•\tSorting to meet the data classification provided;\n•\tConfirmation of all appropriate permits to sort waste and (if required) transport waste;\n•\tProvision of a risk assessment in advance of any collection and sorting;\n•\tAttendence at an inception meeting via Teams and attendance at regular contract meetings during peak delivery periods (30 minutes/fortnightly or as required) and any other communications as required leading up to and required between project phases;\n•\tDelivery of the project outputs as set out in section 5;\n•\tPresentation of the results of the project (online via teams)\n•\tFinal close down meeting (1 hour duration online), anticipated to be held February / March 2027.\nScope of work\nSorting and categorisation requirements\nSeparately recorded sort data will be required for each block/bin store, for each phase of the WCA. This will be comprised of up to 15 blocks in total (across three local authority areas), with approximately 500-700  properties' waste across these, per phase.\nResidual, dry recycling and separate flexibles (where applicable) will require sorting into the high level categories set out below.  Appendix 1 shows the required sub-catagorisation of materials for each of these high level categories.\nPhase 1:\nWaste stream\tClassifications\tData\nResidual waste (all bins in bin area/block)\tTarget flexibles\nNon-target flexibles\nNon-flexibles dry recyclables\nFood waste\nAll other waste\tKg/hh/wk per bin area/block for each category\nDry recycling (all bins in bin area/block)\tTarget flexibles\nNon-target flexibles/\nNon-flexibles recyclables\nFood waste\nAll other waste\tKg/hh/wk per bin area/block for each category\nPhase 2:\nWaste stream\tClassification (group)\tData\nResidual waste (all bins in bin area/block)\tTarget flexibles\nNon-target flexibles/\nNon-flexibles recyclables\nFood waste\nAll other waste\tKg/hh/wk per bin area/block for each category\nDry recycling (all bins in bin area/block)\tTarget flexibles\nNon-target flexibles/\nNon-flexibles recyclables\nFood waste\nAll other waste\tKg/hh/wk per bin area/block for each category\nCapture rate of target flexibles (where applicable)\nSeparate flexibles bins (where applicable)\tTarget flexibles\nNon-target flexibles/\nNon-flexibles plastic recyclables\nAll other waste\tKg/hh/wk per bin area/block for each category\nCapture rate of target flexibles\nFor flexibles in all waste streams, in addition to target/non-target classification, a more detailed compositional classification is required.\nThis may be amended/condensed during discussions with the appointed bidder but as an indication this may include the detail in the table below.
