Garden Composters

Composting is fun and easy! Whether you own or rent, if you aren't composting yet, you are missing out on a great opportunity to reduce landfill waste and feed your garden with rich, black compost. Did you know that you can compost yard waste, weeds, kitchen scraps and even your restroom visits with the right composter? Your plants and your planet will thank you for taking up this simple, environment saving and garden enriching hobby. The Greener EnergyStore provides an excellent sample of the best composting products on the market.

We currently offer composting toilets and composters for the garden. Some composting toilets are "self-contained" (a.k.a. Standalone ) units that don't even require water. Some units are even non electric. These look a bit different from a traditional toilet because the compost is collected in a drum within the unit and can be accessed when it's ready to be used. These stand alone units are ideal for cabins or even houses that could use an extra bathroom - without the work and cost of extra plumbing. Imagine having an additional "powder room" for only $2000. There is even a mobile version of the stand alone toilet made for RVs and boats. Other composting options include Whole House System. These systems are composed of a toilet and a separate composting unit, which is usually placed below it in the basement. These toilets look like regular toilets and can be waterless or low flow (1 pint flush) toilets. A whole house system for a family of 6 is about $2000. The amount you'll be lessening your environmental impact is worth much more than that!

More info on Composting

Be sure to do your homework to make the most of your composting. Although it is relatively easy, in order to produce top quality compost, you will want to pay attention to the moisture level and content. You may want to add Sun-Mar Compost Sure Bulking Material. It consists of coarse peat moss and chopped hemp stalk to aid in the decomposition. The proper compost consistency aids the break down of material, as does proper ventilation. A small DC powered fan that can be run using a small solar panel and battery can accelerate airflow in all non-electric units. It comes pre-installed in an 11" piece of 4" diameter vent pipe so that it will fit inline in your vent stack. It also protects against downdraft and increases the evaporative performance of your non-electric unit by about 10 to 15%.

Continue reading about garden composters and more! or View all If your needs do not call for a new toilet, perhaps you would consider composting food and garden scraps to enrich your soil and also reduce waste. No matter where you live, Sun-Mar Garden Composters make composting convenient. The design keeps animals out of the compost and allows you to easily turn your compost as needed - no shovel needed! Keep in mind that some garden composters can weigh 60 pounds empty and hold 100 gallons or more of compost. That is a lot of compost!

What is compost? Compost is made up of decomposed organic material that can come from your kitchen or your garden. The best compost is made up of organic material from plant sources. Keep meat meats and dairy products out of your compost because they will attract unwanted pests. Compost is widely used in gardening as a rich soil additive. Here at the Greener Energy Store we encourage composting by offering the perfect compost bin and a selection of composting toilets for installation in the home. These environmentally friendly, well designed and high tech composters help the environment, offer real value and give you the perfect place to dump garden weeds, fall leaves and table scraps you don't want to waste in the garbage. If you recycle paper, plastics and aluminum, you are ready for compost!

The BigBelly® Solid Waste Management System

Click Image for PDF

"Big Belly" is a trash bin with built in compaction.  It is solar powered and requires no power connection.The compactor reduces trash volume by up to 8 times -- this reduces the number of garbage truck pickups, which in turn reduces energy use and GHG emissions.   Big Belly has very carefully designed power management, and can go for many cloudy days without running out of power. The BigBelly® Solar Compactor is a patented compacting trash receptacle that is completely self-powered. Instead of requiring a grid connection, BigBelly uses solar power for 100% of its energy needs. The unit takes up as much space as the "footprint" of an ordinary receptacle—but its capacity is five times greater. Increased capacity reduces collection trips and can cut fuel use and greenhouse gas emissions by 80%. BigBelly also provides cost efficiencies from labor savings, fuel cost and maintenance savings, as well as environmental benefits from reduced emissions of greenhouse gases and other pollutants. Safe, easy to use, and designed to keep out pests, the BigBelly has already proven its worth in urban streets, parks, colleges, arenas—and in all weather conditions. Contact Us !

Compost Toilets

Choose from Self-Contained and Central Composting Toilets. Much cleaner and healthier - for you and the environment - than other waste receptacle products.

Self-Contained units are waterless, and so require no connection for water or sewage. This makes installation very quick and easy. They are also more suited to winter operation because it is often easier to keep the bathroom warm. Capacity is up to 6 adults seasonally, 3 adults residentially (Excel model).

Central Composting Toilet Systems are ideal for those that want a "regular" looking toilet in the bathroom, or who want to connect more than one toilet to the composting unit. They are normally placed under or outside the bathroom. Units are often installed up to 15-20ft. away from the bathroom. Capacity is up to 10 adults seasonally, 6 adults residentially (Centrex 3000 Series).

RV / Marine

The Ecolet family of composting units are the first composting toilets specifically designed to recycle waste on boats and recreational vehicles. Less pump-outs! No more chemical toilets! Recycling brings freedom, with the ODOR-FREE operation of a Sun-Mar

Product Name


Sun-Mar Heater Option (12V) for Mobile Models


Sun-Mar Mobile for Boats & RVs



Self-contained units are installed directly in the bathroom. They are available in both electric and non-electric versions. Electric units plug into a regular AC outlet (AC/DC units also use DC electricity) to power a fan and a thermostatically controlled heating element in the base of the unit. The composting toilet is normally unplugged if it is not being used for 3 days or more.
  Composting capacity varies with the size of the Bio-drum. Electric units normally have more capacity than non-electric units because they have extra warmth and air movement.
The most important advantages of self-contained units are:

  • Being waterless, they need no plumbing or water connection. Making them quick & easy to install.
  • More economical than central units because there is no separate toilet.
  • Better suited to winter operations than central units, because it is often easier to keep the bathroom warm.

Most units evaporate all liquids in seasonal operation. Since the whole waste stream is recycled, government approvals are not normally required.
