We are excited for @ABSugarplc commitment to #ecofriendly #plastics. We hope plastics made from agricultural sidestreams can be part of that future. xitter.cf/ABSugarplc/status/9942…
Our vision is that all our #plastic packaging will be reusable, recyclable, biodegradable or compostable by 2030 absugar.com/our-2030-global-…
