The use of natural fibers, in general, and as reinforcement in biocomposites, in particular, has been increasing steadily in the last two decades. These biocomposites are finding myriad applications in automotive, packaging, consumer goods, and construction industries. The annual biocomposites conference in Cologne, Germany, celebrates this growth by awarding the most innovative products made of biocomposites. The winners of the 8th Biocomposites Conference in 2019 reflect the diversity of such applications. Golden Compound from Germany won the first place with its certified home compostable coffee capsules,KNNCellulose from the Netherlands took second place with their biocomposite granulatesmade from recycled toilet paper, andBcompfrom Switzerland achieved third place with their PowerRibs, a composite material made of natural fibers for high-performance applications in lightweight construction. Previous winners of these awards have included diverse range of products like coffin, musical instruments, and vase. In the automotive sector, biocomposites are primarily used for reducing the overall weight of cars (interior components like headrests, seat backs, armrests, door panels and trunk liners). Also, shorter cycle times, scratch resistance and a lower CO2 footprint play a crucial role in the technical applications of biocomposites in the automotive industry. In this area, the demand is ongoing and more or less stable. Some 80,000 tonnes of wood and natural fibers are already employed in the 150,000 tonnes of composite parts for cars and trucks made in Europe each year, according to the nova-Institut from Germany (nova-Institut f€ur politische und €okologische Innovation GmbH). Its analysis estimates that every European passenger car now contains an average of 1.9 kg of natural fibers and 1.9 kg of wood fibers, and from a technical point of view, much higher volumes are possible. Another potential market, which has been developed recently, uses biocomposites for small new electric cars and racing cars. In the construction industry, wood-plastic composite (WPC) decking and railing were first developed in North America in the 1980s as a good way of recycling wood and plastics, and they created the greatest demand for WPC materials in decking applications throughout the world. A strong consolidation has since taken place on the WPC decking market.
