Business case approved for Wellington's new sludge minimisation facility
The new facility is a significant and critical investment in 'Wellington's future. It will reduce the mass flow of sewage sludge going to landfill by more than 80 percent, and help the Council meet its targets of halving its emissions by 2030 and becoming a net zero carbon capital by 2050.

Biosolids Emissions Assessment Mode
Biosolids Emissions Assessment Model (BEAM) is an independent project of North East Biosolids and Residuals Association (NEBRA) and Northwest Biosolids. It builds on the work of the Canadian Council of Ministers of the Environment (CCME) that aims to help biosolids managers understand their greenhouse gas (GHG) emissions (carbon footprint) and find ways to maximise climate benefits. The spreadsheet modelling tool calculates net GHG emissions from various biosolids management processes and allows comparisons for planning purposes. An updated version of the model, BEAM 2022, is currently under development and expected to be published soon.
