Developing effective strategies to deal with accumulated plastic waste and cross-contamination issues GEN: One of the shortcomings of employing single use is the buildup of accumulated plastic waste. We asked representatives from several companies if their firms have a program for dealing with this challenge of increased plastics waste. If not, what solutions did they envision? Could the disposal issue represent such a costly obstacle that a firm might downgrade this component of its production chain?   HP: In reality the amount of plastic generated by companies employing single-use bioprocessing is a tiny fraction of the global worldwide plastic usage. The single-use bioprocess industry uses less than 0.1 % of the plastic resin produced globally. So, while it may appear to be a “mountain of plastic waste” at a plant level, it represents, in fact, an insignificant quantity compared to the global quantity of plastic used for packaging. In addition, in the biotechnology industry, this waste must be managed according to very strict regulations and waste treatment paths. It will therefore not end up wandering into the environment as is sometimes the case with plastics used by the co...
