Communal waste storage – Requirement for this to be external in Criterion 1 - KBCN1513

Communal waste storage areas can be located within the building. However, where such waste is stored internally, it must be in a location that demonstrably provides suitable environmental conditions, meets relevant fire, health and safety requirements for waste storage and has appropriate external access for waste collection.

Off-site waste sorting / no dedicated on-site waste storage - KBCN0696

BREEAM assesses the dedicated space for recyclable waste storage, assessing the asset's physical design and layout without relying on management practices that are subject to change. However, we recognise that in specific cases this is not always possible. Accepted scenarios for off-site waste management Requirements and evidence - NC, RFO and BIU Commercial Using an off-site waste sorting approach must still meet all other relevant assessment criteria for the relevant scheme. This includes:
Requirements  Evidence
Waste stream segregation - If recycling is separated: a minimum of three operational waste streams are segregated using clearly identifiable and labelled containers or bags. - If recycling is mixed: show evidence that the waste is later separated into identifiable recyclable streams. Confirm: - Number of waste streams and collection arrangements. - Post-collection segregation (where applicable). - An on-going waste recycling contract.
Operational waste management - Internal waste storage arrangements, defined on-street collection points and scheduled collection times collectively fulfil the functional role of an operational waste management facility. - Storage arrangements must be suitable for the waste streams generated and be durable, hygienic, and clearly labelled. A waste management plan which: - Outlines how the waste is managed and stored between collections. - Shows interim storage is adequately sized based on the frequency of collection.
Accessibility - Waste storage and transfer arrangements must be reasonably accessible to relevant asset users and allow for safe preparation of waste for collection. - Relevant drawings or documentation.
Compliance for all points above must be demonstrated on a case-by-case basis, and the assessor is responsible for confirming that the intent of the issue — facilitating optimal reuse and recycling of operational waste — is achieved. Additional clarification for BIU Commercial V6 Rsc 02 This BIU issue further segregates operational waste into recyclable waste, construction waste, and reusable construction products.
