    Nature Loo™ capacity expansion

    Nature Loo™ | NL3 — Additional Chamber / OOS

    Add another NL3 chamber to increase available chamber rotation and allow more composting-retention time between uses.

    The chamber is manufactured from rugged polyethylene and matches the batching pathway used by the Nature Loo™ NL3.

    Why add another chamber

    Extend retention time and system flexibility

    Adding another chamber means each chamber can remain out of service for longer before it needs to return to the active toilet position.

    This can improve batching flexibility where the standard three-chamber rotation is not sufficient for the intended users or operating conditions.

    An OOS chamber may remain set aside for composting or be managed through the applicable secondary-composting pathway.
