NSF Certified Composting Toilets: meeting NSF standards

nsf

NSF composting toilets are a great way to go green and reduce the amount of water you use. They're NSF certified, meeting all NSF standards for safety and sanitation.

The best part is that they can be used in any type of setting - from your home to your cabin in the woods!

There's no need to worry about using too much water or having an unpleasant odor because these composting toilets keep everything clean and sanitary without any chemicals.

What are composting toilet systems?

A composting toilet is a type of dry flush toilet that handles feces via the biological process of composting. It's a basic composting system for human waste, similar to those used in gardens.

They usually have a vent system (sometimes called an evaporation chamber) that exhausts air from the composting waste container to assist reduce moisture content and keep the compost healthy and odor-free.

The two sorts of composting toilet systems are self-contained composting toilets, sometimes known as split system composting toilets, and central composting toilets.

This technique decomposes carbon and organic elements to produce compost from human feces. Microorganisms carry out the composting process under controlled aerobic conditions (primarily bacteria and fungus).

Because they do not require water to clean or flush, the majority of these toilets are referred to as "dry toilets" or "waterless toilets."

After each use, a carbon supplement such as sawdust or peat moss is given to various types of composting toilets to help in the decomposition of solid waste. This method creates air gaps in the feces, allowing them to breakdown aerobically.

This also raises the amount of carbon and nitrogen in the air, reducing the chance of smells.

Here is a link to our complete guide about composting toilets (internal link).

They're a sort of wastewater treatment system that uses little to no water and doesn't require a sewer or septic system hookup, an alternative to conventional flush toilets that you'd find in your bathroom.

A composting toilet is ideal for holiday houses, personal residences, RVs, cottages, and just about any other form of habitation!

NSF composting toilet standards

For a variety of reasons, people purchase composting toilets. Some people could be seeking for a toilet flushing mechanism that doesn't use as much water.

Others may be looking for a system that can create finished compost that can be handled without needing to be discharged directly into the environment.

Whatever your reasons and no matter which composting toilet system you decide to adopt, it's. important to be certain that it does what it says. This is where the NSF standards come in.

What actually is the NSF?

The NSF stands for the 'National Science Foundation'- it is an organization of the US government that supports vital research in the field of science.

They're in charge of keeping the US on the cutting edge of research in fields ranging from astrophysics to zoology. As a result, in addition to financing standard academic research, the agency also promotes "high-risk, high-reward" ideas, new partnerships, and a slew of other initiatives that may appear science fiction today but will be commonplace tomorrow.

They also guarantee that research is completely linked with education in all cases, ensuring that today's innovative work is also teaching tomorrow's top scientists and engineers.

The NSF have a set of standards that all composting toilet product manufacturer, must meet- these standards are in accordance with NSF's ANSI standard 41.

What are the NSF standards/criteria?

There are 6 standards/criteria that must be met for composting toilets to be allowed:

-The toilet system is capable of handling the specified capacity for a lengthy period of time, as well as occasional overload.

-There are no unpleasant scents in the toilet system.

-It has been proven that the composted output meets the specified bacterial content levels.

-Advertisement, literature, and labeling are not deceptive.

-The producer does not have access to products that are undergoing testing.

-Parallel testing of field-operated toilet systems confirms lab test results.

NSF International certifies composting toilet products after a thorough examination procedure, ensuring that they will operate as advertised.

When in doubt, look for the label on the product to ensure that your composting toilet has been independently certified and quality checked to satisfy stringent public health design and performance requirements.

The NSF has a list of NSF certified composting toilet- you can search manufacturers or traders on their website and find out whether or not they're NSF ansi standard 41 certified.

NSF ANSI standard 41: What is it?

ANSI standard 41 is simply the set of standards used for composting toilets- the NSF website has a different set of criteria for each type of water and wastewater system/product.

NSF/ANSI Standard 41 certifies composting toilets and similar treatment systems that do not use a liquid saturated media as a primary means of storing or treating wastes.

How to get NSF certified?

The NSF certification process varies depending on the product, method, or service being certified, as well as the kind of certification, but it typically consists of seven steps:

  • Submission of an application and information
  • Product assessment
  • Product testing in a laboratory
  • Inspection of manufacturing facilities, production confirmation, and product sampling
  • Examining and accepting test findings
  • The contract was signed, and the items were listed.
  • Plant inspection and testing on an annual basis

What does NSF certified mean?

NSF certified simply means that the product adheres to all 6 of the criteria set by the NSF and the product essentially does what it says.

Sun Mar: NSF certified

Sun-Mar, founded in 1983, is a pioneer in composting and recycling technologies. Based on innovative product designs and patented technology, the firm has gained global leadership with its full line of composting toilets and garden goods.

To assure and maintain high quality standards, Sun-Mar develops, assembles, and distributes each product.

The National Sanitation Foundation (NSF) has only approved Sun-Mar composting toilets for residential use to NSF/ANSI Standard #41.

Products are distributed through a global network of thousands of dealers. Sun-Mar is a privately held corporation based in Ontario, Canada, with operations in New York, USA.

Sun Mar products are user friendly and designed to be easily installed and low maintenance.

The brand manufactures many different models of composting toilet systems, from self contained to portable toilets, to central composting toilets which is a single unit for residential use.

The installation of these toilets tend to be simple with a straight forward manual to follow. They also tend to be free from bad odors and is a great way to save water and produce natural compost and fertilizer for your gardens.

The cost of these toilets vary from model to model- you can find a detailed article on composting toilet costs and prices here (Internal link).

Conclusion

To conclude, the NSF criteria has to be met by manufacturers to ensure that buyers are getting what they're promised.

Does the composting toilet do what it says it does? Does it function how it's supposed to? Does it pose any dangers if installed or maintained incorrectly?

It is in your best interest to ensure that the composting toilet you're buying holds NSF certification.
