    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 Drain-FX system attaches to any faucet with a removable aerator and by narrowing the flow, creates a pressure washer that can be used to clear clogged drains without chemicals. Reaching a pressure level of 250 psi, the manufacturer claims that the system can break down clogs within one minute. Parts consist of a tool to remove the faucet aerator, a pressure adapter, and a drain clearing hose. The company offers models with varying hose lengths according to the use: the Drain-FX mini for bathrooms, Drain-FX sinks for the bathroom and kitchen, and Drain-FX plus and ultra for the bathroom, kitchen, and laundry.

    J&J Flooring Group’s Kinetex is a soft surface floor covering intended for use in place of hard surfaces such as vinyl composite tiles in medium- to high-traffic commercial applications. These 24" x 24" semi-rigid tiles are 0.20" thick, compared to 0.25"–0.60" for standard carpet tiles, and are engineered with a wear layer made from solution dyed PET that resists staining or bleaching and is woven for abrasion resistance and durability. Kinetex is made from 60% recycled content (50% post-consumer PET sourced primarily from water and soda bottles) and, unlike carpet, can be ground and processed into new backing in one step without costly material separation and sorting or loss of performance. Kinetex is treated with perfluorinated compounds to resist dirt and improve its lifespan, but its long-term environmental impact is a concern to GreenSpec.

    The Silver Bullet reduces both bacteria and scale with a UV-light-based non-chemical water treatment system. The ultraviolet light catalyzes atmospheric oxygen into monatomic, ionic oxygen atoms that mix with the water to form hydrogen peroxide. The hydrogen peroxide is non-toxic to humans and animals, but effectively treats the water for bacteria. When the hydrogen peroxide contacts ambient calcium in the water it gives that oxygen atom back up, forming calcium oxide or quick lime. This quick lime cannot form scale, instead becoming a precipitate that can be filtered out. Any residual hydrogen peroxide decays back into water. The use of catalytic UV lighting for water treatment greatly reduces the electrical costs of filtration, and use of chemical water treatment.

    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.

    The E-Treat water conditioner, distributed by Sierra Solutions, is a whole-house scale-preventing water treatment using template-assisted crystallization (TAC). Water passes through a two-chamber tank containing activated carbon and anti-scale media, which attracts and crystallizes calcium and bicarbonate ions and prevents them from accumulating as scale on the plumbing. The system can handle 12 gpm of water with a maximum hardness of 7 grains. E-Treat requires no electricity, salt, or backwashing.

    These two-chamber composting vessels are hand-rotated for aeration and require no electricity. The systems are specially designed for batch composting: one chamber is filled first and continues to be aerated while the second chamber is filled with fresh waste. The systems require a carbon amendment, typically in the form of wood pellets, which balance the nutrients and also absorb extra moisture (otherwise, leakage may occur). The units are well insulated for outdoor use, and composting continues in cold weather. The JK270 can serve the needs of a school or a small multifamily community (10–12 full-time residents), according to the company; the JK400 accommodates larger cafeterias and commercial kitchens or can serve the needs of 20–30 full-time residents in a community.
