Ahead of the final negotiation round for a UN Global Plastic Treaty (INC-5), we speak to Alexandra French, CEO of British natural polymers company Xampla. French hopes the INC-5 will result in binding rules forcing a reduction in fossil-based polymer production, opening market space for bio-based alternatives.French says the negotiations also risk leaving regulations at the guideline level, meaning petrochemical states can continue mass-producing single-use plastics. She argues that policymakers attending the negotiations need to be aware that this would be a less profitable route in the long run. We also discuss Xampla’s latest developments.
