Recycling and recuperation
Waste is also a key focus. "By implementing numerous individual measures, by 2023 we will have reduced the waste per produced machine by approximately 20% compared with 2019," explains plant manager Dirk Pressgott. In production, an innovative painting process reduces the amount of paints and solvents used while offering the same paint quality. HAMM also recycles the solvents used for cleaning the painting systems. Internal logistics also saves energy by optimising routes and also uses quiet electric forklift trucks. Shortly before the rollers leave the plant, the brake energy is recovered via recuperation at the test bench, which all machines pass.
Intelligent solutions instead of materials
In general, "intelligent solutions instead of materials" applies in purchasing and logistics at HAMM. Special transport racks therefore render much of the packaging superfluous. And, thanks to a 4PL strategy, there are virtually no empty runs when supplying purchased parts and semi-finished products. In addition to these measures, suppliers are selected based on their environmental certification and training of employees with a view to environmental protection. Through dialogue with the Design and Production departments, HAMM has also been continuously reducing excess packaging and optimising transport capacity for many years. Recycled plastics are also used wherever possible for constructing rollers.
Environmentally friendly products and compaction solutions
With regard to products, HAMM follows the objective of "developing low-consumption machinery and machine control systems that ensure an efficient and, therefore, resource-friendly work process on the construction site," explains Dr Axel Römer, Head of Research and Development. Specific examples of this are compaction with oscillation, which emits little noise and conserves resources; process optimisation through digital tools and networking; and consumption-reducing technologies in the area of the power train. HAMM rollers can also be operated with non-fossil fuels such as biodiesel or hydrotreated vegetable oil (HVO). Today, many machines can already work with these types of fuels, and applications are being expanded. Biodegradable hydraulic oils are also part of the standard supply range.
Environmentally friendly operation and service for long machine life
Durable products are especially sustainable. This is where HAMM's telematics system comes in to play, as the service life of the rollers is extended through regular maintenance – and with optimal availability. The long service life of HAMM rollers is also reflected in the spare part philosophy. HAMM still supplies customers with spare parts for all models ever built. Moreover, most spare parts can be ordered separately – not just in assemblies.
