About MacroCycle

MacroCycle uses a patented chemical process to upcycle end‑of‑life plastics and polyester waste into virgin‑grade PET and polyester resins. The technology synthesizes macrocycles, achieving up to 80 % lower energy use than traditional recycling and enabling zero‑carbon production when powered by renewables, while delivering drop‑in material that meets PCR regulations without a green premium.

Company Description

Problem

Plastic and polyester waste accumulates in landfills and oceans, creating environmental pollution and contributing significantly to global CO₂ emissions. Existing recycling methods either produce low‑quality material, require high energy inputs, or involve costly premium pricing, limiting their adoption and impact.

Solution

MacroCycle uses a patented chemical process that converts end‑of‑life plastics and polyester waste into virgin‑grade PET and polyester resins. The technology synthesizes cyclic macromolecules (macrocycles), enabling recycling at approximately 80 % lower energy consumption than conventional methods and allowing the remaining energy to be supplied by renewables for zero‑carbon operation. The resulting resins match market‑grade quality, can be sold at standard market prices without a green premium, and meet PCR regulations, helping manufacturers reduce Scope 3 emissions and eliminate landfill and ocean‑bound plastic waste.

Features

Proprietary macrocycle synthesis process that upcycles PET and polyester waste into virgin‑grade resin

Energy usage up to 80 % lower than traditional mechanical or chemical recycling methods

Capability to power the process with renewable energy for zero‑carbon production

Drop‑in resin compatible with existing manufacturing lines, eliminating the need for equipment changes

Compliance with PCR regulations and certification for use in consumer‑grade products

No green premium pricing; resin sold at standard market rates

Target Audience

Primary customers are manufacturers of consumer goods, packaging, and textiles that require high‑quality PET or polyester resin and aim to meet sustainability targets while maintaining cost competitiveness.
