5 steps towards Net Zero in wastewater management

For Net Zero Week 2023 we have highlighted five key ways industry can work towards minimising the environmental impact of CO₂ emissions associated with their wastewater treatment and management activities.

‍

1. Improve energy efficiency

‍

Identify and implement energy-efficient technologies and practices throughout the wastewater treatment process. This includes optimising pump and filtration systems, ensuring effective Cleaning in Place, regular ongoing maintenance, and employing advanced process control strategies to reduce energy consumption.

‍

2. Renewable energy generation

‍

Install on-site renewable energy generation systems to offset the energy demand of wastewater treatment facilities. This can include wind turbines, solar panels and anaerobic digesters fed by organic wastewater.

‍

3. Biogas recovery and use

‍

Capture and use biogas generated during the wastewater treatment process. Biogas is produced when microorganisms digest organic matter in wastewater. This biogas can be used as a renewable energy source for heating, electricity generation, or can be converted to steam for boilers.

‍

4. Carbon capture and reuse

‍

Still in its infancy, carbon capture and storage technology can capture a high percentage of CO₂ emissions from industrial activities. Captured carbon can be stored underground or reused for purposes such as enhanced oil recovery, building materials and more.

‍

5. Offsetting carbon emissions

‍

The feasibility and applicability of these approaches may vary depending on factors such as budget, industry, location, available resources and regulatory framework. After implementing as many appropriate strategies to reduce CO₂ emissions, remaining emissions can be offset through carbon reduction and conservation projects.
