Deal Overview
PulpStream has developed a process to convert contaminated and mixed paper waste—food-soiled cardboard, waxed paper, multi-layer cartons—into premium molded fiber packaging that replaces EPS foam and plastic clamshells. Traditional paper recycling rejects 15-25% of collected paper as contaminated; PulpStream uses enzymatic cleaning to process these rejected streams. Their molded fiber products are fully compostable and cost-competitive with plastic alternatives at scale.
