The pilots will be carried out in partnership with three London local authorities with five pilot sites (blocks) in each. The local authorities are: •London borough of Bexley (twin-stream dry recycling service) •London borough of Lewisham (comingled dry recycling service) •Royal Borough of Kensington and Chelsea (commingled dry recycling service) The 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. A 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. Pilots are still being finalised but are likely to include the following: In-home options External infrastructure options* 1 No home separation - resident behaves as now (control) Usual recycling bin 2 In-home separation using residents own bags Standard wheeled bin (lined) / Lid-in-lid bin (lined) / Sack holder 3 In-home separation using rolls of bags delivered by the local authority Usual recycling bin (co-mingled) / Lid-in-lid bin (lined) / Sack holder 4 In-home separation using provided storage caddy (non-compaction), with residents using own bags Standard wheeled bin (lined) / Lid-in-lid bin (lined) / Sack holder *External options are being finalised with local authorities, and depend on local factors such as available space and collection and sorting methodology. Blocks will have a weekly collection frequency of residual waste and dry recycling, as a minimum. The 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. 3. The brief The following project deliverables will be undertaken by the succesful bidder: • Two 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. Phase 1: Pre-pilot WCA - to be undertaken between 7th - 26th September 2026 before interventions are introduced Phase 2: Post-pilot WCA - to be undertaken late January/early February 2027 to assess impact of interventions • Sorting to meet the data classification provided; • Confirmation of all appropriate permits to sort waste and (if required) transport waste; • Provision of a risk assessment in adv... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/flatflex-waste-composition-analysis-ocds-h6vhtk-06c08b) ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** complete - **CPV codes:** 79822000 - **Delivery regions:** UK - **Estimated Value:** £45,000 - **Contract Period:** 11/08/2026 to 31/03/2027 ## Awards & Winning Suppliers (1) - **Award:** 1 (active) - Supplier(s): **RECYCLING OF USED PLASTICS LIMITED** - Supplier identifiers: `GB-FTS-168508` ## Contracts (1) - **Contract:** 1 (active) - Signed Value: £62,476 - Signed Date: 31/08/2026 ## Provenance and Official Sources - **Official Notice:** [Find a Tender Notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F061423-2026) - **Last Source Update:** 2026-09-29T13:20:22.000Z - **This document generated:** 2026-10-08T11:25:35.058Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-06c08b
