The energy used for the business processes of Herstaco, HTW (Herstaco Tube Welding) and GPCS (Global Pipe Cleaning Services) mainly involves electricity, diesel and natural gas. Welding the steel pipes uses most of the energy in the form of electricity. All the electricity used is green, as it is supplied by our 360 solar panels. Should this not be sufficient, we purchase the additional electricity needed from Dutch wind power.
To heat our office, we use natural gas. Our office building was inspected in 2022 and awarded energy label A+++. It is an ongoing process to make our office building even more energy efficient.
Our work equipment such as cranes and forklifts run on diesel. We use Diesel ChangeXL. This fuel is based on the action of natural enzymes (also known as biocatalysts). The enzyme concentrate causes a molecular change in the fuel, making combustion better and faster, with fewer emissions. The use of this alternative fuel provides Herstaco with a Co2 reduction of 8%. In addition, our equipment is fitted with Adblue to reduce nitrogen oxides by 85%.
Selling surplus material is sustainable. We buy up (residual) lots from oil companies and factories. By doing so, we give well-used pipes, new or used, a second chance. This reduces CO2, particulate matter and other emissions.
To match supply and demand, we handle pipe lengths economically. Steel residues are recycled. GPCS takes care of the removal of PE or PP coating. After removing the coating, the pipes are reused. The removed cladding is transported to a specialised company and recycled.
We use wood for various purposes. To avoid wasting wood, we encourage hauliers to come and load with tongue-and-groove trailers. We also reuse wood, such as dunnage from ships, used chocks and beams. Surplus wood is offered and reused by local businesses or artists, among others. The amount of wood is thus minimised. We charge the customer for the wood we use.
