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

BREEAM assesses the dedicated space for recyclable waste storage. This must be a permanent structure on-site, or space in the asset. Where this space does not exist: For NC or RFO The aim of the issue is met by provide evidence covering all points 1-4:

A waste management plan which provides on-site storage between collections, adequately sized based on the frequency of collection.
An on-going waste recycling contract.
The typical recycling rates from the waste management company.
A permanent structure (or internal space) within the asset site boundary that can be converted to comply with all criteria requirements. Layout drawings must be provided showing how this space could be converted in future, including meeting all relevant criteria for: • User and vehicle access, • Area requirements for waste storage, • Appropriate size and number of containers for the expected waste streams, and • Space allowance for any additional waste processing requirements e.g. compactors, composting containers, water outlets etc.

This ensures that there is:

A robust off-site waste management strategy,
Proof of future convertibility for on-site waste storage.

For BIU The above approach for NC / RFO only applies to waste storage for construction fit-outs, which are temporary in nature. It does not apply to any other credits, and compliance cannot be met based on future commitments. This means that the above approach:

Does not apply to recyclable waste storage. Answers C + D | Rsc 02 | BIU Commercial V6.
Does apply to off-site sorting for construction waste arising from fit-out activities. Answer E. Only points 1-3 apply - a future commitment for permanent storage facility is not required.
Do not apply to the storage of reusable construction products Answer F.

For BIU, new storage areas will be recognised once they are completed and assessed in future certification cycles.

Operational waste requirement for catering – applicability - KBCN1162

The additional operational waste storage requirement for developments which include catering is generally only applicable where a commercial scale kitchen is present. Where the design team can justify that there will be no significant waste streams from a modest facility, such as a small cafe, selling only drinks and pre-prepared snacks, the additional waste storage area identified in the default values does not need to be provided to meet compliance.

Operational waste storage sizing - KBCN0560

The dedicated space requirements given in the technical manual are default guidance, for situations where it is not possible to demonstrate the required size based on known waste streams. Compliance can, therefore, be achieved provided that it is clearly demonstrated and evidenced that there is adequate justification for the type of facilities & size of waste storage provided, and that the assessor is satisfied that the sizes and facilities meet the criteria based on the building type, occupancy and the likely waste volumes generated as a result of these.

Recyclable, general and organic waste storage – space, labelling and segregation - KBCN1577

Strategies may vary according to the specifics of each project, their waste streams and collection arrangements.

Any reference to ‘labelling’ refers to permanent markings or fixed, robust and weatherproof signage.
Colour coding of bins to identify waste streams is not in itself compliant labelling.

The aim of these requirements is to encourage recycling, ensuring that it is correctly sorted and to prevent cross-contamination of waste streams. Label the recycling area This is required to alert building users and collection agencies to the location of the recycling facility. Label each recyclable waste stream This can be done by labelling the bins or their dedicated space within the recycling facility, or both. Mixed recycling bins and / or spaces are clearly labelled with their constituent waste streams. General or organic waste have their own dedicated spaces Sufficient space for general and, where relevant, organic waste is required in addition to meeting the requirements for recyclable waste. This does not have to be within a separate facility, but if combined with recyclable waste storage, there is greater risk of cross-contamination. The following requirements apply in this situation:

For organic waste, see also additional hygiene-related requirements within the technical manual.
In line with the requirement for the recycling area to be clearly labelled, general or organic waste must be stored in labelled bins and in a labelled, dedicated space within the combined waste facility.

If provision of waste bins is out of scope Where the provision of waste bins is outside the scope of the developer, it is clearly not possible to label the bins. In this situation, the following compliance options are available:

Provide compliant signage to the storage area and label bin spaces within the storage area according to the relevant waste streams.
Where future waste streams are unknown, provide compliant signage to the storage area and a written commitment from the developer to ensure that the bins and/or bin spaces are labelled.

21-May-2024 - Link to KBCN0696 removed. Merged with KBCN1380. Minor clarification added on mixed recycling.

Self-contained dwellings / bedrooms with shared facilities – mixed recycling - KBCN1664

Where there is mixed recycling, the number of recyclables containers can be reduced to match the final waste streams being collected. For example, the standard BREEAM requirement is three recyclables containers per dwelling / communal facility.

Where there are two waste streams (for example mixed paper, plastics and metals with a separate glass collection) then only two containers are required.
Where there is only one waste stream, only one container is required.

The total combined storage volume requirements are the same as stated in the manuals. To apply this KBCN, the project team must provide evidence to QA of the waste collection policies that apply to the asset.

Suitability of waste storage facilities - KBCN0186

In situations where direct vehicular access to the recyclable waste store is limited by logistics or if size is a problem, for example inner city locations, some flexibility to the application of the criteria is allowed. The assessor can use their judgement on whether the storage space is appropriately sized and if the distance and changes in level via lifts or steps are acceptable. Convenience, H&S issues and the volume and type of waste likely to be generated must be considered. Where the assessor deems the arrangement to be satisfactory this would be acceptable. Typically ‘accessible’ is defined as being within 20m of a building entrance. In some circumstances site restrictions or tenancy arrangements could mean it is not possible for the facilities to be within 20m of a building entrance. If, in the opinion of the BREEAM assessor it is not feasible for the facilities to be within 20m of a building entrance, their judgement can be used to determine if the facility is deemed to be ‘accessible’ to the building occupants and for vehicle collection.

Waste management practices - KBCN0247

16/04/2018 This compliance note is no longer valid as it does not fully explain how to approach this Issue. Please refer to the technical guidance and other compliance notes, such as KBCN0696, which deals with co-mingled recyclable waste. ^{The requirement to provide a dedicated space for the segregation and storage of operational recyclable waste, as well as relevant facilities (e.g. for large amounts of packaging and/or compostible waste), relates to the building, not the occupier or the local authorities. A dedicated space and facilities must be provided irrespective of the waste management practices of the relevant stakeholders.} ^{The BREEAM certification relates to the building, not the occupier's or the local authorities' waste management practices. Therefore, the provision of a dedicated space and the relevant facilities is required to ensure the building's operational recyclable waste streams is diverted from landfill.}

^{22/02/2017 Amended to include facilities (in addition to dedicated spaces)}

Waste storage provision for catering - KBCN0755

As the manual states, the additional 2m2 per 1000 m2 of waste storage area provided for catering is measured against the "net floor area where catering is provided" and NOT the floor area of the catering facility. Generally, a catering facility will serve building users throughout the building. If it can be demonstrated that this is not the case, for example if part of the development is subject to a separate tenancy, not served by the catering facility, the area calculation can be adjusted accordingly. Where the net floor area is not indicative of the actual occupancy, the default values may not be appropriate. In such cases, the predicted waste streams should be calculated based on the actual occupancy and waste streams generated. This requirement accounts for the increase in waste produced by building based on the likely number of building users served by the catering facility. Please note that these default calculations are only intended for use where it is not possible to determine accurately what provision should be made based on predicted waste streams.

Water outlet - KBCN0824

A water outlet referred to in criterion 3.c is meant to be any device able to supply water (tap, faucet, hose, etc.)

[Withdrawn] Labelling and signage – Where provision of waste bins is out of scope - KBCN1380

[This KBCN has been merged with KBCN1577]. Where the provision of waste bins is outside the scope of the developer, it is clearly not possible to label the bins. In this situation, the following compliance options are available:

Provide compliant signage to the storage area and label bin spaces within the storage area according to the relevant waste streams.
Where future waste streams are unknown, provide compliant signage to the storage area and a written commitment from the developer to ensure that the bins and/or bin spaces are labelled.

See also KBCN1577 It is recognised that the bins may be provided by the tenant, local authority or waste management company after the time of certification.

21-May-2024 - Withdrawn. Merged with KBCN1577.
22-Mar-2023 - Updated to align with KBCN1577 and to clarify applicability to all assessment types where providing bins is out of scope.
