BillerudKorsnäs debuts climate-positive packaging

Co-developed by BillerudKorsnäs and LafargeHolcim, D-Sack is a dissolvable sack for cement and other construction materials that “disappears” during the mixing process, eliminating packaging waste while helping to ensure a cleaner and safer workplace, BillerudKorsnäs explains.

“When exposed to aggregate, water and mechanical action, D-sack disappears and becomes part of the concrete, mortar and finally, the new building. The carbon fixed in the paper fibres during photosynthesis in the growth period of the tree also becomes part of the building, making D-Sack climate-positive,” according to the company video.

In a lifecycle assessment conducted by IVL Swedish Environmental Research Institute, D-Sack was found to capture CO2 over a one-hundred-year perspective, explaining that the CO2 captured from the atmosphere during tree growth and then incorporated into the paper is stored in the concrete structure.

“It is an innovation that has been produced in our sack laboratory in close cooperation with LafargeHolcim designed to meet specific user needs and needs in the value chain. The sack laboratory has done an excellent job and set the standard for innovation in the packaging industry,” Mark van der Merwe, Business Development Director, Sack Solutions, BillerudKorsnäs, says.
