How Does an Acceptance Test Work?

Cyrill Hugi
Founder, Chief Executive Officer

What all innovations have in common: they pose major challenges for the authorities. Where normally a clearly defined catalogue of questions can be ticked off, there is nothing for the officials to follow. That can be annoying, for both sides.

The approval of our pyrolysis system for operation in Europe took time. What slowed us down were also the official obstacles. It is a complex matter doing everything you have to do to commission a new system that has never existed before. Even with the oil refining plant that we bought, which therefore had a customs code, we encountered unexpected problems.

Example of a hose coupling

It was about the return flow of oil when refuelling. We prevent the environmentally harmful leakage of oil with a so-called hose coupling. The valve is designed according to the principle of volume displacement: overpressure prevents a drop of oil from escaping when coupling.
 
These valves, also known as low-leakage valves, are used in the transport of chemicals, for example, where fluids are often many times more harmful to the environment than our oil. We were therefore proud to meet the highest standard. However, the hose coupling was a challenge for the water protection authorities. It was to cost us several weeks and two expert opinions.
 

In Appenzell we say «s'menschälät», which means "it's human".

If there is no guideline for something, the authorities have two options. They can look for another directive to follow, or they can ask for an expert opinion that proves that there is no risk. In our case, the risk was of polluting a body of water. Somewhat naively, we thought that we would pass the test with flying colours. After all, hose couplings are used all over the world and do exactly what they are supposed to do: they prevent liquid from escaping. 
 

The human factor: «s'menschälät»

What we didn't reckon with was the human factor. In Switzerland, we have an expression for this. In Appenzell, we say «s'menschälät», which means «it's human». We humans react irrationally and make decisions emotionally. What is new and unfamiliar to us really attracts our attention. We are more critical, more rigorous and much more precise. That makes perfect sense. This is how we learn whether the unknown is good or bad for us.

Certain things are required of us that are otherwise handled much less strictly.

Our coupling system was subjected to this critical test. The office wanted proof that it really worked. And not from us, but from an external expert. And then also from the expert that we initially paid for an expert opinion. We had to have the same expert report done again by someone else until we took another step forward with the authorisation.
 

Return

Authorisations always take a lot of time. And because we provide completely new solutions, certain things are required of us that are otherwise handled much less strictly. For example, the lorries that deliver heating oil to households in Europe do not have a coupling with a hose coupling. After the filling process, the hose is drained. After decoupling the tanker driver simply holds the pipe upwards to prevent it from flowing back. Then he clamps the pipe to the lorry. And that's it. For enespa, handling oil in this way would be a no-go.

When designing the systems, long before the first weld seam, we make sure that our machines fit into the container dimensions. This is necessary because every mile on the road would cost 800,000 dollars.
