Dow Chemical's microfoaming technology is to help mitigate the carbon footprint of the Rio 2016 Olympic Games in flexible packaging.
Paloma Alonso, Dow Packaging and Speciality Plastics Latin America commercial president, says: “Packaging plays an important role in helping minimise food waste. The leveraging of the microfoaming technology as one of the Rio 2016 carbon mitigation projects promotes a rational utilisation of packaging and showcases how it can help enable reductions in greenhouse gas emissions.”
Dow believes that in addition to driving differentiated performance in the packaging industry, the microfoaming technology enables reductions in greenhouse gas emissions through new production methods that lead to higher productivity and improvements in the extrusion process of films.
Tania Braga, Rio 2016 head of sustainability, legacy and accessibility, says: “As the official chemistry company of the Olympic Games and the official carbon partner of Rio 2016, Dow is engaging the value chain to help us deliver on our carbon mitigation commitments. The microfoaming technology project is a clear example of how Dow is leveraging the power of the Olympic Games to influence the packaging industry towards lower carbon solutions.”
The project is being implemented in partnership with manufacturers located in Valfilm in Brazil, Petropack in Argentina, Folmex in Mexico and Plastilene in Colombia and Guatemala, as well as MuCell Extrusion.
Dow is currently working with external partners to quantify the expected reductions in carbon emissions from this process. After verification by independent auditors, the results – along with those from the other projects being implemented in Brazil and Latin America – will be applied toward the mitigation of Rio 2016's carbon footprint.
Microfoaming is a licensed technology developed to reduce weight and add a more sustainable profile to plastic films and packages. Dow's microfoaming technology allows lightweighting in coextruded films through physical foaming. This ensures more packaging material is produced using the same amount of resin. The technology can also be used to develop flexible packaging food as well as for collation shrink, food, cosmetic, hygiene and cleaning sectors, for applications that include stand-up pouches, laminated PE, PE PET, PE and BOPP films.
