NEW – Simploo Mini – Waterless Composting Toilet


Delivery time is approximately 6 weeks for the Simploo Mini

The all new Mini from Simploo, compact, stylish design that despite its small footprint packs a punch with its capacity featuring a 9 litre urine bottle and 19 litre solids container. The new mechanical vanity hatch conceals the solids but can be opened with the flick of a lever on the outside of the loo. The Mini is manufactured with plant based plastic, a renewable resource using state of the art 3D printing technology.

Capacity – Pee
The urine canister has a capacity of 9 litres and includes a removeable lid for carrying.


Capacity – Poo
The solids container has a capacity of 19 litres. Toilet paper can be added to the solids bin.
Built in Pee Alarm
The Simploo Nano and Mini both feature an alarm that’s built in to the shell of the loo and notifies you when it’s time to empty the bottle.
Easy emptying
The seat, lid, mechanical hatch and separator are combined into one unit which is easily removeable to access the liquids and solids containers
Wherever you live
Ideal for Camper vans, tiny houses, boats, caravans, tents and more
Built in Fan – no need to drill holes in your loo
All Simploos include a built in fan that not only helps dry out the solid waste and removes condensation but also removes odours, venting either to the outside or to an optional carbon filter.
The fan can be be positioned on the left, right or rear of the loo. To relocate it simply pull it out and push fit it back in. Blanks are included for the unused holes. In the unlikely event that the fan fails, simply push out the fan cartridge and push in a new one.
Environment and Sustainability
The Shell, Bottle, Hatch, Top Frame and Solids Container of the Simploo Mini are manufactured from Plant Based Plastic (Polylactic acid), a renewable resource unlike oil based plastic. Polylactic acid is recyclable and biodegradable*
Without the need for water and chemicals the Simploo mini offers complete travel freedom and removes reliance on emptying facilities such as elsan points.
Plug and Play Installation
With the option of suction cup feet and an attachable carbon filter, installation couldn’t be easier. The suction cups stick to any smooth surface and the carbon filter removes odours. The Simploo Mini can also be screwed to the floor.
Manufactured in the United Kingdom
All Simploo Waterless toilets are manufactured in Datchet, Berkshire, UK

*What is Polylactic Acid (PLA)

What is PLA?

PLA is 100% bisourced and biodegradable, one of the first renewable polymers to compete with traditional polymers in terms of performance and environmental impact! Because it emits three times less C02 emissions and is already on the market, PLA could very well reconcile plastic with the planet. Here’s everything you need to know about this bioplastic.

Polylactic acid to those in the know

The abbreviation PLA comes from polylactic acid.

Chemist Théophile-Jules Pelouze first synthesised PLA in 1845. In 1954, the chemical company Dupont patented an industrial synthesis process. Learn about the history of plastic in 15 key dates. In the 1960s and ’70s, this polymer was used in biomedical applications because it could degrade under physiological conditions. Because PLAs is non-toxic and biocompatible, it’s often used to make biodegradable suture strings and implants for sustained drug release.

In the 1990s, PLA expanded into other uses. The company Cargill developed a ring-opening polymerisation (ROP) process that allowed it to synthesise high-molecular-weight PLA (called PPLA) on an industrial scale (sold in pellet form). Thanks to its mechanical properties and biodegradability, PLA can replace non-biodegradable polymers such as PET and polystyrene.

Researchers have since discovered even better ways to design PLA and create formulations for specific applications.

PLA: a biosourced and biodegradable bioplastic!


PLA is a bioplastic that is both biosourced AND biodegradable, whereas most bioplastics are either biosourced OR biodegradable, but rarely both at once!

PLA is classified as a 100% biosourced plastic: it’s made of renewable resources such as corn or sugar cane. Lactic acid, obtained by fermenting sugar or starch, is then transformed into a monomer called lactide. This lactide is then polymerised to produce PLA.

PLA is also biodegradable since it can be composted. However, its compostability had until recently been limited since it required constant high temperatures, meaning it could only be composted in industrial plants. Furthermore, the time it took to disintegrate meant it could only be used to produce thin films with a limited quantity of PLA (and therefore few biosourced components). This problem has now been entirely resolved thanks to Evanesto®, the first additive that has allowed PLA-rich plastics to obtain the OK HOME certification from the Tüv Austria organisation. This additive allows microorganisms in the compost to assimilate PLA more quickly and easily, ensuring that plastic packaging and products (even rigid ones) can be added to home composters along with food scraps and other kinds of biowaste.

A growing field of application!

PLA resins can be used without major adjustments to the plastics industry’s existing tools: a significant advantage that means the entire sector can now use PLA.

PLA is a transparent and rigid polyester at room temperature, seting it apart from other compostable and biosourced resins currently on the market. PLA has a transparent and shiny appearance similar to glass, is easy to print on, is resistant to fats and many organic compounds and solvents, and has intermediate barrier properties like polystyrene. PLA can therefore replace fossil-based products in many applications.

Because PLA is safe to use with food, it’s most commonly found in this sector (bags, pots, capsules, packaging, tea bags, etc.). But it’s expanding to an increasing variety of applications: in the home (floor and wall coatings, curtains, protections, textiles, bin bags, vacuum cleaner bags, toys, electronic appliances, wipes, nappies, etc.), electronics (smartphone protection, computers), various types of packaging, hygiene (wipes, nappies), agriculture (pots, films, strain, clips, etc.), cars (dashboards, trims), and industry (poly bags, blisters, bubble wrap, etc.).

PLA has quickly become the most common filament in 3D printingPLA’s biodegradability fits perfectly with the spirit of 3D printing (producing the strict minimum, on-demand, onshoring). In addition, 3D printing filaments are often made of PLA because of its thermal and mechanical properties.

The future belongs to PLA

Driven by strong demand, the bioplastics market keeps increasing and is expected to grow between 10 and 15% per year by 2025 (and the good news is that it won’t compete with human or animal food production). PLA is 100% biosourced and biodegradable, one of the first renewable polymers to compete with traditional polymers in terms of performance and environmental impact! This is why its production has continued to increase since 2001.

There are now two main global producers of PLA: NatureWorks LLC and Total Corbion PLA. To respond to this market growth, the joint-venture Total Corbion PLA, created in 2017 by Total and the Dutch company Corbion (a lactic acid specialist), started up production of a new PLA range under the brandname Luminy® in 2018. This PLA is be made from GMO-free sugar cane at its plant in Rayong, Thailand (which has a name plate capacity of 75,000 tonnes per year). Total Corbion PLA is also planning to start up production at its Grandpuits site in France in 2024 (name plate capacity of 100,000 tonnes per year).

Other companies are also emerging in this field: in Asia, the joint-venture Anhui BBCA & Galactic (with an annual capacity of 40,000 tonnes); PLA NEO Futurroqui, which is planning to produce 100,000 tonnes by 2024, as is PLA ZERO (based in South America). This means that within the next four years, companies will be able to produce 600,000 tonnes of PLA per year, enough to meet the needs of many markets.

An effective solution to fight against pollution from useful plastic


It remains hard to replace plastic in certain cases. This observation is shared by the Citizens’ Climate Convention in France, which states that “packaging remains necessary for many products for health reasons or to ensure product quality.” Compostable plastic, and therefore PLA, is an alternative that will allow us to keep using plastic, all while protecting the planet.

In June 2020, the Citizens’ Climate Convention recommended “establishing mechanisms to promote the use of biosourced materials that can be composted and even—over time—fully biodegraded.”

Though you may not have known about PLA before reading this article, you’re likely to use it (and compost it) every day very soon!
