Rochling Automotive’s new bioplastic uses 90% renewable raw materials

New Rochling-BioBoom claimed to be an ecological and economical alternative to most conventional materials such as polyester but also polystyrene (ABS), polyolefins (such as PP) and polyamides (PA6).

Green materials ensure sustainable mobility: The automotive industry is increasingly working on aligning vehicle production with the principles of sustainability. The development of appropriate materials plays a decisive role in this process.

With the bioplastic Rochling-BioBoom, Rochling Automotive is the first company on the market to have a patented polylactide (PLA)-based biopolymer that consists of at least 90 percent renewable raw materials. In this way, the company offers an ecological and economical alternative to most conventional materials such as polyester (PC, PET, PBT) but also polystyrene (ABS), polyolefins (such as PP) and polyamides (PA6).

‘We want to support our customers in the development of environmentally friendly vehicles and thus help shape the transformation of the industry towards a sustainable one,’ explains Prof. Dr. Hanns-Peter Knaebel, Chairman of the Board of Management and CEO of Rochling Automotive. ‘With our bioplastics, we are bringing a sustainable solution to the market that originates from a completely self-controlled supply chain – from renewable resources to the automobile manufacturers’. Rochling Automotive has built up internal expertise in materials development over many years in cooperation with various partners.

With significant improvements in terms of thermal stability and chemical resistance compared to standard PLA, the new biopolymer family meets the company’s high technical requirements and specifications.

Rochling BioBoom enables greenhouse gas emission savings that are about 70 percent higher than those of PP and almost 90 percent higher than those of PA6. This means that if the proportion of petrochemical plastics in a mid-sized car is replaced by Rochling Automotive’s bioplastics, 515 kilograms of CO2 emissions can be saved per vehicle production.

Three standard types of Rochling Automotive biopolymers are currently available, which are suitable for applications in the engine compartment and underbody as well as for the interior of a vehicle. Each of the three types can be tailored to individual customer needs and the respective specific requirements. Röchling BioBoom can also be used for almost the entire product portfolio of Rochling Automotive.

For Prof. Dr. Hanns-Peter Knaebel, the sustainable material is also an initial indicator for a green future for the company: ‘We have set ourselves the goal of becoming the leading supplier of bioplastics and recycling materials in the automotive industry by 2035 at the latest. This means that we will noticeably increase our development activities in this area’.
