Description: Bioboost Mark II: Decarbonizing Biosolids Drying using Hydrogen
Bioboost Mark II: Decarbonizing Biosolids Drying using Hydrogen
Abstract
The New Plymouth Wastewater Treatment Plant (WWTP) is owned and operated by New Plymouth District Council (NPDC or Council), and services approximately 87,000 people. Since 2002, Council has achieved close to 100% beneficial reuse of their biosolids by selling them as a granular fertilizer product Bioboost®. The current dryer is a rotary drum dryer, fueled by natural gas, and was the first such dryer installed in New Zealand. This paper looks at the critical success factors for Bioboost® and also explores the question “where to next?”, as the thermal dryer which produces Bioboost® reaches its end of life, and is replaced in a new facility with a larger drum dryer, partially fuelled by hydrogen
The New Plymouth District Council (NPDC) dries its biosolids in a thermal drum dryer, fuelled by natural gas. The dried pellets are marketed as a fertiliser, trademarked as Bioboost®. The existing dryer has reached the end of its service life and needs replacing. In assessing replacement options, NPDC decided to build a new facility around a larger drum dryer, but decided that it should be duel-fired, with 25% of the energy demand met by a new hydrogen supply to reduce its carbon footprint.
