Present and Future of (Not Only) Rope Making Technologies. Chapter 1. Present Times
Principles (part 1) • Recyclable raw material recourses. • Renewable material or spare part recourses. • Reusable or recycled packaging material. • Educational activities aimed at end user to really help in “production-distributor-end user” product cycle.
Principles (part 2) • Sophisticated technologies for gaining maximum performance from minimum material used. • Sophisticated chemicals for biodegradability. • Manufacturer’s involvement in local environmental issues. • Manufacturer’s involvement in keeping the climbing or caving environment in tact.
Benefits • Much higher transparency of involvement in environmental issues. • Being part of larger projects where voice of one is too weak, but joint force of more companies is useful tool in negotiation. • Possibilities of help with sometimes-straightforward unseen solutions or help with complicated issues.
Step 1 • Processing of production-waste multifilament PA6 fibre (ropes, cords, webbings) • Processing of multifilament PA6 fibre from used products (ropes, cords,webbings) and making secondaryproducts from it • Future prospects of recycling of multifilament PA6 fibre (making new from old)
Step 2: Pioneering Brand New Technology Dynamic ropes
Technology Description Dynamic ropes
Sheath material reduction 8,3% Dynamic ropes
10 Tons PA6 Savings Potential Dynamic ropes
Pioneering Brand New Technology Static ropes
