Abstract
The use of natural, renewable raw materials is becoming increasingly important in industry and research due to their environmentally friendly production and disposal. Compared to fossil raw materials, which are produced from fossil fuels such as oil and coal, natural materials are in principle inexhaustible. Natural materials bind large amounts of CO2, but are also often burned to generate heat or energy or processed into biogases or fuels. However, it makes sense to an intermediate step between harvesting and disposal. The use of renewable raw materials offers the potential to substitute the use of petroleum-based products. The use of renewable raw materials significantly reduces the emission of CO2 into the atmosphere. Furthermore, renewable raw materials can usually be disposed of relatively easily compared to products based on fossil raw materials. The latter often cannot be completely or economically disposed of or recycled in an environmentally sound manner. Even when materials and material composites made from renewable raw materials are thermally recycled, no additional climate-damaging CO2 is produced, but only as much as was previously bound. Renewable materials decompose much faster than most petroleum-based plastics, provided that no chemical adhesives have been used when bonding the natural, renewable raw materials. This paper presents first investigations of sustainable joining systems for renewable raw materials such as wood, bamboo and natural fibres. The results show that wood and bamboo can also be reliably joined by rotary butt friction welding
