Dispose of your empty and non-hazardous lab plastics in an eco-friendly way with this Zero Waste Box! Any brand of rigid lab plastics like centrifuge tubes, plastic bottles, trays, vials, and beakers are welcome (but coated gloves and overshoes are not invited). Please refrain from sending in biodegradable materials, metallic items, heavily soiled or contaminated materials. And definitely keep out any hazardous medical waste - we don't want any bloody or fluid-filled specimens from healthcare facilities or research labs, sorry!
