Text on a box of doughnuts caught my eye – it read: “This window is recyclable, repulpable and plastic-free.” …What I eventually found out is that the term “plastic-free” isn’t nearly as simple or self-explanatory as it sounds, and that making single-use packaging greener is a complex challenge for everyone involved. …And apparently two years ago, A Plastic Planet stopped certifying bioplastic as plastic-free. …Laura Parlagreco, Astro Box’s vice-president of operations, said the window was made of cellulose acetate from wood pulp “sustainably sourced from fast-growing eucalyptus trees.” …As a confusing array of bioplastics hit the market, A Plastic Planet raised its standards and no longer thought bioplastics met the bar for being “plastic-free.” The group worried that the certification could be used to greenwash products that didn’t break down into nutrients for nature.
