Waste professional sizes your waste storage area (and small projects)

Technical Clarification Number


If a waste management professional has established that the allocated size of the space for recycled waste (including general waste) is sufficient for the development, this is acceptable as an alternative to the table Mat-1.1 sizing requirements, however the project team will need to provide the following as part (not solely, unless it includes all documents types/information requested by the technical manual) of the credit submission:

- Waste and Recycling Management Plan (Signed by the building owner)
The Waste and Recycling Management Plan must address all waste (recyclable and non-recyclable) generated in the building (occupants, common areas and visitors) and the dedicated storage area for the separation and collection of recyclables must be sufficiently sized (as per the technical manual or waste professional advice) to handle the collection and sorting of all waste streams for the following recyclables as a minimum:
- Cardboard;
- Paper Products;
- Glass;
- Plastics; and
- Metals

The Waste and Recycling Management Plan must describe, at a minimum:
• Estimation of waste generation and justification of the size of the recycling area. This justification must be made by the waste management professional and must be based on calculations of the estimated waste generation quantities. All calculations must be well explained in the WMP and clearly conclude that based on these calculations and the proposed frequency of collection, that the size of the recycling waste storage area is in fact sufficient;
• Description of the waste storage areas, in terms of location, size, accessibility, easy access for manoeuvring bins and cleaning storage areas;
• Proposed waste recycling strategy; what waste is separated and recycled; and how;
• Transfer of waste bins to storage areas; in terms of surface (free of steps, kerbs), distances;
• Description of the collection points, ease of collection, access for collection vehicles;
• Frequency of collection.

For a small project (<2500m2 GFA) the ’waste professional’ can be a member of the existing project team who is adequately involved in the project and suitably experienced in sizing waste storage spaces (this will be at the AP’s discretion).

Recycling waste storage - multiple waste storage areas

Technical Clarification Number



It is acceptable to meet the Credit Criteria of Mat-1: Recycling Waste Storage with more than one dedicated storage area. However, all storage areas dedicated to recycling must meet all the Credit Criteria and Additional Guidance requirements (such as location within 20m of a lift core) and be sufficiently sized, functional, safely and easily accessible.

An area dedicated exclusively to storage of rubbish (non-recycling waste) should be excluded from the calculations of the recycling waste storage area. Note that if general (non-recycling) waste is stored in the same location as the recycling waste, the area must be increased by a minimum of 25%.

In addition, where other uses (retail or multiple tenancies) are present in the building, it must be clearly demonstrated that the office use of the recycling waste storage facilities is not compromised (e.g., how a proportion of facilities is dedicated for exclusive use of the project).

The recycling waste storage area can be provided by more than one dedicated space, but at least one of the waste storage areas must be a minimum of 7.5m2.

Alternative compliance for recycling waste storage on a precinct level

Credit Interpretation Request Number


The project team must demonstrate that the size of the dedicated storage area provided within the building is sufficiently sized to accommodate the storage recyclable waste generated between collection intervals as per TC MAT1-T-OB1-0593.

The project team must further demonstrate that the centralised waste facility has sufficient space to store all the waste from the buildings (and any future buildings) within the precinct as per the credit guidance in allocating space size, page 218. Alternatively, this can be demonstrated as per the methodology stipulated in TC MAT1-T-OB1-0593. The project team must also provide a signed letter of confirmation from the relevant governing body (i.e. the precinct Property Owners Association representative) stating that that the waste recycling centre is operational at the time of practical completion of the building and that all tenants (including the project) are authorised to make use of this centralised facility. The extracts from the tenant guidelines must be provided to show the requirements for waste collection and frequency of collection.

Do note that all other credit criteria remains and the project must comply in order to be recognised for their effort.

Multiple GFA space types

Technical Clarification Number


As per the Green Star SA – Office v1 Technical Manual (Page 219), “if multiple uses (e.g. retail and multiple tenancies) are present within the building, this cannot compromise the value of the amenity for any of the uses”. This statement is to be interpreted that recycling waste storage area(s) sized in accordance with Table Mat-1.1 using the commercial office GFA only (i.e. other space type GFA excluded), would only be deemed to meet the Credit Criteria if additional area(s) is provided for waste generated from the non-commercial office GFA (e.g. retail, restaurant etc.). Where no additional area(s) is provided and only the minimum as per Table Mat-1.1 is provided, it is reasonably assumed that waste generated from the non-commercial GFA would be stored within the area(s) and “compromise the value of the amenity” for the commercial office GFA recycling waste management.

The GBCSA does not prescribe guidelines for area of recycling waste storage (per m2 GFA) for non-commercial office GFA (e.g. retail, restaurant etc.) and Project Teams are permitted to use their professional and informed discretion as to the additional area provided for waste streams from these space types. It is suggested that the figures presented in Table Mat-1.1 are used as a guide, but are not compulsory.

The requirement to increase waste storage area(s) by 25% should general waste be stored in the same location as recycling waste, as per the Green Star SA – Office v1 Technical Manual, is applicable to commercial office waste storage area(s) only.
