Sustainability Problems:
- Heavy airplanes use more fuels and thus emit more carbon dioxide.
- Weak cargo nets can break, shift cargo and cause accidents and death.
- Weak protection for workers in many industries cause injuries and fatalities.
Technology:
Dyneema is brand cargo nets made of fabric that is made from fibers of ultra-high-molecular-weight polyethylene (UHMWPE), 15 times stronger than steel, has longer lifecycle but weighs half as much as polyester cargo net. It floats on water. It does not get heavier when wet so it is easy to handle and thus reduces accidents and injury among ramp workers. The use of Dyneema nets cuts the weight of commercial, cargo and military planes, reduces fuel consumption and reduces carbon dioxide emission by 2.5 tons per year per net. Dyneema working gloves are cut-resistant. Dyneema can stop bullets, pull oil tankers and harness the power of wind. Dyneema ropes and slings for fishing, maritime, mining and forestry industries are very strong and lightweight, and help in to work more efficiently and safely.
It is invisible to UV light and thermal imaging devices, can withstand extreme cold and hot temperatures and has high electrical resistance, is fire resistant and self-extinguishing. Dyneema products are costly. Dyneema has longer lifecycle than polyester nets but its cost is four times as more. Dyneema’s high cost hinders it from being used widely in the markets.

Stakeholders:
Airline companies , police and military workers, Industry workers, forestry, mining, marine industries, policymakers
Implementation:
– Lobbyist and policymakers should try to lower the cost of this material so that more people can have a grip to this technology. Although it is used by some industries, most people who would buy other much cheaper but weaker brands thus accidents due to breakage of weak ropes and nets could still occur.
– Governments in developing countries should work with private investors so that poor people in developing countries can avail of the products thereby solving more energy and safety problems that this technology can address. Dyneema should partner with stakeholder industries and try ways to lower the cost of their products.
– Further research on this product’s design and increased competition should be addressed to lessen the cost of Dyneema products.
