BMW:BMW Group uses sustainable paints made from bio-waste

Munich. The BMW Group is using innovative
technologies in its efforts to improve sustainability and taking
advantage of new options to conserve resources and reduce emissions
from painting bodywork. The BMW Group is the first automotive
manufacturer worldwide to use matt paints made from biomass instead of
crude oil at its European plants. In addition to this, BMW Group
Plants Leipzig and Rosslyn (South Africa) are also using
sustainably-produced corrosion protection. Renewable raw materials
such as bio-waste or waste from sewage treatment plants serve as the
starting material for the paints. The CO2 savings
determined in a TÜV-certified process amount to over 15,000 tonnes of
CO2 emissions between now and 2030.

“By reducing our use of fossil raw materials, we can conserve natural
resources and lower CO2 emissions at the same time. To
achieve this, we are increasingly relying on sustainability
innovations in our supplier network,” says Joachim Post, member of the
Board of Management of BMW AG responsible for Purchasing and Supplier
Network. “Innovative paints based on renewable raw materials are an
important step in this direction.”

Organic waste replaces fossil resources

BASF’s innovative production process makes it possible to replace
petroleum-based precursors, such as naphtha, with renewable raw
materials from organic waste, starting in the early stages of paint
production. This not only reduces consumption of fossil resources, but
also avoids the CO2 emissions associated with the
production, transport and processing of crude oil.

The corrosion protection and matt paints used at BMW Group Plants
Leipzig and Rosslyn are chemically identical to the paints previously
used, with all the same properties as conventionally manufactured body
coatings. Since bio-based and conventional coatings are produced on
the same line, BASF adopts an externally certified mass balance approach.

The amount of paint purchased by the BMW Group is calculated to be
exactly equivalent to the amount of bio-naphtha and bio-methane that
would be required for 100-percent petroleum-free production. The
sustainable manufacturing process reduces the CO2 emissions
from paint production by more than 40 percent. The two BMW Group
plants in Leipzig and Rosslyn produce an average of around 250,000
vehicles per year.
