Trelino Composting Toilets: The Perfect Portable Solution for Campers

Trelino Composting toilet

If you're an avid camper or outdoor enthusiast, you know the importance of having a reliable and convenient toilet solution while on the road. That's where Trelino Composting Toilets come in. These innovative portable toilets are designed to provide a hassle-free and environmentally friendly option for your camping adventures.

I have had many weeks of experience in different camping locations with one of these units and I have to say that I will not be camping without one of these moving forward. I really did not know what I was missing out on having one of these handy. Read on to find out all about this product as I go over my experiences with it.

Introducing The Trelino Evo S

Trelino Composting Toilets are meticulously crafted of high-quality plastic, combining engineering excellence with a deep understanding of the needs of outdoor enthusiasts. These toilets are designed to be easy to use, lightweight, and highly effective in separating liquid waste from solid waste. The intelligent separation system eliminates odors and simplifies the disposal process.

I was amazed at how easy storing away this unit was and I will be giving a few tips and tricks about the different things I did or use to make life easier with this item.

The Key Components of Trelino Composting Toilets

A Trelino Composting Toilet consists of a body, a lid, and a toilet seat. Its inner parts include two containers and a separator insert. The separator insert is the heart of the toilet, as it effectively separates liquid waste from solid waste. The urine is diverted to the front into a canister with a special membrane to prevent leakage and odors. This might sound weird, but I love how everything is just located in simple locations and how simple it was to have everything just fit right. I was never uncomfortable while using this unit. I've made pool noodle toilets before and those were never comfortable and would usually only be a one or two times use scenario.

I know you all know how to make a pool noodle toilet 🤣.

The solid waste is collected in a separate container lined with a reinforced and non-transparent garbage bag. I ran out of garbage bags pretty quick so that 10 pack bag from dollar tree sure did come in handy.

The Importance of Drying and Odor Prevention

To ensure a dry and odor-free experience, it is crucial to enhance the drying process of the solid waste. After using the toilet, it is recommended to sprinkle the solid waste with natural materials such as very fine sawdust, small animal litter. This drying process prevents the formation of bacteria, which are responsible for the usual odor associated with traditional toilets.

I found it best to use what I currently had on hand. I got some wood chips from my grandparents' garage before heading out. Hopefully my grandpa doesn't realize that I am the one who is dipping into his stash.

Easy Emptying and Cleaning

One of the key advantages of Trelino Composting Toilets is the ease of emptying and cleaning. Both the liquid and solid waste containers can be removed separately from each other. They can both be emptied into any toilet connected to the sewage system, also the solid waste can be disposed of in residual waste or used for composting. But who wants to use regular poop as compost. Not me.

The separating inserts have a special coating to support drainage and can be easily cleaned with a mixture of vinegar and water.

Advantages of Trelino Composting Toilets

Trelino Composting Toilets offer a range of advantages that make them the perfect choice for campers and outdoor enthusiasts.

  • Portability and Versatility

One of the key advantages of Trelino Composting Toilets is their portability. They are lightweight and easy to transport, making them ideal for camping trips, overlanding, and weekend getaways.

  • Environmental Friendliness

Trelino Composting Toilets are an eco-friendly alternative to traditional chemical toilets. They eliminate the need for water and chemicals, reducing the environmental impact of waste disposal. By separating and drying the waste, these toilets promote natural decomposition and can even be used to generate high-quality soil for fertilizing your own garden.

  • Odor-Free Experience

One of the biggest concerns when it comes to camping toilets is the odor. Trelino Composting Toilets address this issue by effectively separating and drying the waste, preventing the formation of bacteria that cause unpleasant odors. With Trelino, you can enjoy a fresh and odor-free experience, even in the great outdoors.

  • Easy Installation and Replacement

If you already have a chemical toilet installed and are considering switching to a composting toilet, Trelino Composting Toilets offer a seamless transition. They can easily replace pre-installed chemical toilets by simply unscrewing them from the back wall and floor.

Maintenance and Care Tips

To ensure the longevity and optimal performance of your Trelino Composting Toilet, it is important to follow proper maintenance and care practices. Regularly clean the separating inserts with a vinegar and water mixture, and add a few drops of vinegar essence to the urine canister to prevent odor and urine scale formation.

I have a small tip for keeping this unit extra clean while empty or full. I use a product known as Awesome that I get for $1 at dollar tree. You can see an image below. This product is very strong and needs to be diluted with water.
