ANZBP Advisory Committee

The Australian & New Zealand Biosolids Partnership, or ANZBP has been created to promote and support the sustainable management of biosolids in Australia and New Zealand.

The ANZBP operates as a program within the Australian Water Association (AWA), collecting separate partner contributions to specifically support the mission of the ANZBP. Key stakeholders include water utilities in Australia and New Zealand which produce and manage biosolids, consultants and contractors involved in biosolids management, agencies responsible for regulating the management and use of biosolids, research organisations and universities, and end-users of biosolids and their representative groups.

The ANZBP has a corporate model whereby organisations from around Australia and New Zealand contribute partnership funds and all their employees are able to take advantage of member benefits.

The ANZBP is guided by an Advisory Committee comprising of a cross-section of stakeholders, which reports to the AWA Board. Current members of the Advisory Committee are:
