Re-Engineered RotoPowder
Proven safe.
Proven strong.
Recycled polyethylene rotomoulding powder for water tanks, tested to the EU food-contact standard and certified batch by batch.
10,000 tons of RotoPowder sold.10,000 water tanks moulded in our own ovens.That's the field test. Here are the lab tests.
Food-contact and water safety
In our tanks: 40x below EU food‑safety limits
Independently tested to EU Regulation 10/2011, under the conditions the EU uses to represent long-term storage. Water stored in a 1000L tank made from Fenix material sits about 40 times below the EU migration limit, and further below in larger tanks.
Safe for drinking water
Tested according to EU food-contact standards.
A cut-out from a tank made with 100% Fenix material was fully immersed in 20% ethanol for 10 days at 40°C: a harsher liquid than water, held warm. Results from two independent EU 10/2011 test reports.
No traces found of BPA, phthalates, heavy metals, PCBs, dioxins, furans or mineral oils.

Batch quality control
Every pallet tested, every batch certified
No Fenix pallet leaves the factory until it has been moulded, tested and signed off. Every batch ships with its own Certificate of Conformance.
- Rotomoulded part testMoulded sampleSurface integrity, colour consistency, no defects
- Falling dart impact≥ 14.40 J/mmToughness under impact

Traceability
A physical sample of every batch is retained on file. If a question is ever raised about a tank, the exact material it was made from can be retested.
Closed loop
We mould our own tanks from our own material, every day. The material we test is the material we trust in the field.
Colours and grades
A grade for every layer
Every grade is recycled polyethylene powder, made to order and UV-stabilised (except the 3040 liner grade). Choose by layer and application.

“There is great market potential for a supplier of quality rotomoulding grades that can compete with virgin on mechanical properties and reliability but at a lower price. Fenix delivers on their promises.”

Made with Fenix powder
Far more than water tanks
Our moulders turn Fenix RotoPowder into products for farms, homes, sanitation and infrastructure.
Also moulded from Fenix powder: wheelie bins, road barriers, buckets and more.

Sustainability
16,000 tons of CO₂ avoided
Fenix RotoPowder is recycled polyethylene that would otherwise go to landfill. Moulding with it instead of virgin plastic saves about 1.6 kg of CO₂ per kilogram.
The CO₂ that 76,000 trees absorb growing for ten years, already saved by our powder.
Each tree shown stands for 1,000 trees.
One 5000L tank
Based on 1.6 kg of CO₂ saved per kg of recycled plastic used instead of virgin, and 21 kg of CO₂ absorbed per tree per year.
