We give yesterday’s materials a second life in tomorrow’s marinas. What’s already been built doesn’t lose its value but simply finds its way into something new. Our approach keeps materials in use, reduces pressure on natural resources, and supports coastlines that are designed with continuity in mind.

Re-use for more sustainability
When port and coastal structures are renovated, a large amount of waste material is generated.
Traditionally, this is disposed of and only new materials are used for the new structures.
Much of this waste material is still in very good condition and can easily be reused.
This is the aim of Mole Twee.
We want to bring material suppliers and buyers together by making it clear where specific materials are available and facilitating purchases via our platform.
Reducing the environmental footprint of your project
Upon request, we can provide you with a calculation of the CO₂ savings achieved through the materials sourced through us.
As a general rule, any material that is reused helps to protect the environment and conserve our planet’s limited natural resources.
Slow-growing, high-quality woods should remain in use for as long as possible. The same applies to materials that are very energy-intensive to produce, such as steel components.
Steel beams: old, but still serviceable
GRP grid panels: durable and, thanks to their standardised dimensions, ideal for reuse
Why use materials from port and coastal engineering?
Our founder, Philipp, has many years of professional experience in hydraulic engineering and the design of coastal and port structures.
He has always been troubled by the fact that so much material of impeccable quality is dismantled and disposed of without any thought being given to possible ways of reusing it.
And this despite the fact that the materials are very easy to separate. A simple jetty in a marina consists of just a few different high-quality materials, which are typically bolted together. When stainless steel fasteners are used, these materials can still be easily separated even after decades.
Here we find fine woods such as bongossi, basralocus or oak. These woods are very durable, and structures located underwater or in the ground in particular survive for many decades unscathed without losing any of their quality.
More modern materials such as GRP panels or beams are also extremely weather-resistant, easy to dismantle and therefore ideal for reuse.
