  • Aquatron and Dubbletten Toilet Systems
    Rosie's Natural Way
    Rosie’s Natural Way distributes a urine diverting system, called the Dubbletten, and a composting system, called the Aquatron. The Dubbletten is a low-flow toilet with a split bowl that keeps urine separate from fecal waste from the outset; solids go in the back and liquids in the front. A 1.0 gallon flush is used for the back, and an optional “spritz” (0.01 gallons) is provided for the urinal. The urinal has an elastomeric membrane without a trap, but urine goes directly to a storage tank, where it is sealed by an oil solution. Buildings can then use the urine as a nitrogen-rich fertilizer.

    The Aquatron attaches to the back bowl of the Dubbletten or to a conventional toilet to retrofit it into a composting toilet. The system can be installed up to 196 ft (60m) away because a non-mechanical separator installed an angle below the toilet uses centrifugal force to separate 98% of liquids and flush water from solid waste. Solid waste is diverted to a biological chamber where it decomposes into compost. Liquid waste can then be directed through a UV-filter and phosphorous trap, producing water suitable for irrigation. Aquatron systems range in size from 13 gallons (50 liters) for second homes to 3,170 gallons (12,000 liters), designed for use with 10–12 toilets.

    The Nexus eWater system converts a home’s graywater into near-potable water and utilizes waste heat in the water for more hot water heating. The system directs graywater to a collector that has an embedded heat exchanger, which uses refrigeration coils to transfer the heat to the Nexus reHeater. The 70-gallon hot water heater uses 15 kWh per day to heat water to 120°F and has a COP of 4.0. Once the heat is extracted, graywater is pumped through the Nexus reCycler, filtering the water to standards required by NSF-350 at a capacity of 200 gallons of per day. Bubbles are circulated to adhere to soap, dirt, and oils, eventually hardening into a foam that is returned to the sewer. After passing through a UV and carbon filter, the water is near potable and can be used for irrigation or for toilets (code allowing). The system recovers more than 90% of graywater for reuse but requires separate black and graywater plumbing.

    The Zurn’s Z5755 Omni Flow Urinal provides the unique feature of accommodating multiple flow rates from 0.125 gpf to 1.0 gpf. This allows plumbers to install multiple low-flow urinals and set one or two to high flow to help move water down the line, preventing uric salt build-up and pipe corrosion. The urinal comes in a standard size for retrofitting and the flush valve has a 10-year life on the battery. Its asymmetric back wall minimizes splash-back.

    The Steward Hybrid urinal has the same appearance as Kohler's Steward Waterless model, but flushes with 0.125 gpf. This makes it ideal for installing along with the waterless models in order to provide a flush that will help clear the pipes down the entire line. This wall-hung, vitreous china urinal has a large footprint that can cover an old urinal wall print, making it an easy retrofit. A 15 5/8" extended rim and 3/4" top spud allows for ADA installation. The funnel bowl shape minimizes splash-back and a "flushing spreader," located on the back wall is designed to clean the entire bowl. The urinal is WaterSense compliant when used with WaterSense flushometer.

    Full Circle Composting Toilets
    Full Circle offers a waterless composting toilet with modular, interchangeable composting containers. The bathroom commode, available in wood, porcelain, or plastic, uses wood shavings for a "dry flush" and a 4-watt ventilation fan to manage odor. A single commode connects via a sealed plastic chute to a roll-off container the size of a garbage pail stored below in a basement or crawl space. When a container is filled, it is disconnected, capped, and set aside to compost. A new container is wheeled into place and connected to the chute. Both active and resting containers are sealed and connected with the exhaust, and the air-handling system draws air through up through the entire compost bin, supplying oxygen to all corners of the container for complete composting. Containers with completed compost can be wheeled outside and emptied onto landscaping. Maintenance takes 15–30 minutes and happens every six months to a year, according to the company. An electronic light indicates when it is time to swap compost bins. A divided, urine diverting bowl is available, to direct urine into a dedicated drain for storage, treatment, and reuse as fertilizer.

    Temtrol DeltaT. Inc.
    RedyTemp is an electronically activated pumping system and hot water circulator that quickly delivers hot water to a fixture while returning water that has been sitting in the hot-water pipes back to the hot-water tank. It can be programmed on a timer or activated on-demand by a wireless push-button, motion activated, or voice activated system for a single cycle. GreenSpec recommends setting it for on-demand use, which will result in improved energy efficiency compared with using the timer. Aside from quicker hot water delivery, benefits include energy savings (especially compared with continuous-circulation hot-water loops) and the elimination of water waste while waiting for hot water. The system is compatible with tank or tankless water heaters, and is either installed with a dedicated return line or uses the existing cold water line as a return line. RedyTemp can be installed with PEX tubing. It comes with a two-year warranty which can be upgraded to a five-year warranty.
