Biocomposites, which combine the advantages of technical plastics with natural fibres, are currently trending. They offer sustainable alternatives to purely fossil-based materials. WPC (wood plastic composite) is a particularly well-known example. This composite material, made from wood fibres and plastic, is widely used in decking, furniture, and construction products.<\/p>

However, a new generation of sustainable materials has emerged: S\u00b2PC (Sunflower Plastic Composite). These bioplastics are reinforced with sunflower seed shells, a waste product that offers unique benefits.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Wood fibre-reinforced plastics are well-established materials, but their production can conflict with other goals. Wood residues, such as those used in WPC, often originate from by-products of the wood processing industry. However, they are not technically waste products. In times of energy crisis, wood residues are increasingly being used for energy production, for example in the form of pellets for heating. This creates direct competition for the raw material between the building materials industry, the energy supply sector, and the plastics processing industry.<\/p>

The situation is quite different for sunflower seed shells. They are produced in large quantities automatically during the manufacture of sunflower seeds for human consumption. No one would cultivate a sunflower field solely for the shells. Therefore, the raw material is a genuine by-product that has hardly been utilised to date. There are no significant alternative uses.<\/p>

Conclusion:<\/strong> There is no competition in the land use system when it comes to sunflower seed shells, which are a valuable raw material and therefore have a clear ecological advantage.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Another advantage of S\u00b2PC is that the residual oil content in sunflower seed shells acts as a natural lubricant during processing. This reduces friction in the tool, minimises wear and tear, and often enables shorter cycle times or lower processing temperatures. This saves energy, protects machinery and improves the overall ecological balance.<\/p>

Conclusion:<\/strong> Not only are S\u00b2PC materials more sustainable, they are also more efficient in terms of processing technology.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Both natural fibres, wood and sunflower seed shells, have their purpose. Combined with a biodegradable polymer such as Bio-PBS, they complement each other's strengths.<\/p>
