What’s new in this groundbreaking design?

Enhanced Composting Volume: The CM40 Next Gen boasts over 30% more composting capacity, allowing for larger composting loads while maintaining a sleek and compact form. This innovation doesn’t compromise on space, with a reduced minimum underfloor clearance of just 1400 mm.

Efficiency Redefined: The updated design ensures faster composting times and minimizes the risk of blockages, making it the smartest choice for modern composting toilet solutions.

Features and Benefits:

  • Set and Forget Convenience: The continuous composting style requires minimal ongoing maintenance, giving you peace of mind and freeing up your time for more important matters.
  • Baffle Technology: The built-in baffle separates the composting pile from the access door, ensuring that you only handle fully composted material. Say goodbye to dealing with waste directly.
  • Sloped Efficiency: The sloped design optimises the composting process and gradually shifts the pile, ensuring that the most mature composted material moves underneath the baffle into the access chamber.
  • Improved Leachate Management: The CM40 Next Gen introduces an updated leachate storage feature, reducing the risk of drainage system blockages. It also encourages efficient airflow and the evaporation of liquids.
  • Maintenance Inspection Hatch: This innovative design includes a maintenance window, allowing access to the composting pile when necessary. Whether you need to retrieve foreign objects, add extra bulking agents, or level the pile, it’s all made easy.

Versatile Installation: With its reduced underfloor clearance, it’s a great fit for:
