Rheological methods can be used to investigate the speed at which biopolymers, such as polylactic acid (PLA), whose low environmental impact is a defining feature, will biodegrade and compost within landfill. This new data from Malvern Instruments demonstrate how rheological measurements made in the laboratory provide information about the kinetics and thermodynamics of polymer breakdown, helping accelerate the development of products that meet defined biodegradability criteria. The work is presented in a recently recorded webinar entitled Using rheology to assess the biodegradability and compostability of polylactic acid and is freely available for download from the Malvern website www.malvern.com/PLA-biodegradability.
