any harm. As enablers of a circular economy, we invite the industry to join the growing number of partners working with us to bring a circular econo- my vision to life.” The startup has recently won a $100m contract to license its technology to the USA’s Formosa Plastics. It has also entered an agreement to supply the plastic to the giant Japanese-owned conveni- ence store chain 7-Eleven. Famous for its Slurpees, nearly 12 million of these carbonated slush drinks, served in clear plastic cups, are consumed every day, from 7-Eleven’s 77,711 (as of 21 January 2022) outlets in North America, Asia and Scandinavia. In a move they say will “reduce the carbon footprint of plastic”, USA-based firms Heartland and Ravago Americas have executed a joint development agreement to create “the next generation of plastic resins” Ravago is one of the world’s largest plastic
recyclers and compounders. Heartland is a manu- facturer of engineered hemp additives, which is reportedly “building America’s first reliable industrial hemp supply chain to provide additives for manufacturers that use plastics”. Heartland claims its hemp is carbon negative because it absorbs more carbon from the atmosphere while growing than is used in its production and distribu- tion, and that its engineered hemp additives reduce the carbon footprint of virgin plastics by as much as 44%. Heartland has worked alongside Ravago to engi- neer hemp materials as renewable additives for plastics. Ravago’s R&D team guided Heartland in engineering products that do not require plastic compounders and moulders to invest in retooling.
After the 2022 farming cycle, Heartland esti-
mates it will be able to process over 45m kg of hemp additives that will be available for plastic compounding. Ravago and Heartland say they will continue to research and develop products to serve the automotive, packaging and building materials, and markets. Milliken has launched a range of viscosity modifiers specifically designed for PP recyclers, thereby expanding its recycling additives portfolio. The new DeltaFlow range of viscosity modifiers is available in different forms for different applica- tions. Recyclers can use DeltaFlow as a solid concentrate to increase the melt flow rate of recycled polypropylene (rPP) for both extrusion and injection moulding processes. DeltaFlow is available in free-flowing pellets, which makes the product easy to feed, safe to handle and dust free. Milliken says that PP resins that have been
