This series of case studies demonstrate show capital from a variety of sources is influencing plastic material flows across the value chain, with an eye to increasing circularity. This portfolio includes mature examples, such as investments in rPET infrastructure in Mexico, which benefited from multiple rounds of financing, as well as venture-backed, early-stage innovations in reusable packaging and digital transactions for recyclable waste. Also included are high-potential analogous examples, such as the SUNREF program scaling renewable energy in Nigeria, and green bond issuances by the Indonesian government.
