For a sustainable future, it’s important to replace regular plastics with eco-friendly options. The EU project DEEP PURPLE<\/a> investigates using wastewater as a source of biomass to make circular, eco-friendly products using Purple Phototrophic Bacteria (PPB). Along with creating bio-fertilizer, ectoine, and self-healing concrete, the project also works on getting biodegradable plastics from liquid and solid waste in wastewater and this is how they do it.<\/strong><\/p>\n\n\n\n

Every year, wastewater management systems carry tons of biomass to treatment plants. A significant part of this waste, like toilet paper, contains cellulose. The\u00a0DEEP PURPLE<\/a>\u00a0project finds new uses for this cellulose.\u00a0Aqualia<\/a>, a water management company in Spain, collects the cellulose from a wastewater treatment plant. Then,\u00a0ITENE<\/a>, a Spanish research centre, cleans the cellulose and turns it into a white gel called cellulose nanofibre (CNF). Some of this gel is turned into sugars using enzymes, which\u00a0Novamont<\/a>, a technical project partner, ferments into 1,4-butanediol. This compound is a building block for making films and packaging. The rest of the CNF gel is dried and added to concrete and plastic production as an extra ingredient.<\/p>\n\n\n\n

The wastewater, after extracting cellulose, is combined with the organic fraction of municipal solid waste (OFMSW) after thermal hydrolysis at an organic waste biogas plant run by\u00a0FCC Medio Ambiente<\/a>. This mixture is then treated in anaerobic PPB photobioreactors to obtain PHA-enriched biomass through purple phototrophic bacteria.\u00a0Activatec\u00a0<\/a>handles the PHA-enriched biomass, extracting and purifying the PHA for the project partners.\u00a0Natureplast\u00a0<\/a>takes these PHAs and mixes them with CNF to create biodegradable plastic-composite materials.<\/p>\n\n\n\n

NaturePlast has developed formulations using CNF and PHA. These formulations were initially compounded in pilot settings, and later at a semi-industrial scale in NaturePlast’s facilities. The resulting materials were then forwarded to Novamont to produce prototypes.<\/p>\n\n\n
