In 2018, Procter & Gamble (P&G), an American multinational consumer goods corporation, has reached zero manufacturing waste to landfill at 85% of their sites globally and describes how they did it in their 2018 Citizenship Report P&G is the maker of famous brands such as Pampers, Ariel, Downy, Tide, Safeguard, Gillette, among many others.

In 2008, the company launched Zero Manufacturing Waste to Landfill program. At that time, Procter & Gamble's 100-plus manufacturing sites worldwide were producing more than one (1) million tons of waste annually, the company's report notes. Getting to zero "seemed like an impossible dream" at the time, according to P&G. The shift began with employees changing their everyday behaviors and collaborating with the company's Global Asset Recovery Purchases team to find new uses for materials. For example, P&G sells soap that doesn't meet their standards to carwash soaps. Scraps from feminine care products are turned into cut litter, and old shipping drums get repurposed as school benches and tree containers. In the Philippines, P&G partnered with industry group PARMS (which include Unilever, Nestle, among its members) in building a 25 million-peso (US$475,000) facility that aims to turn sachets into plastic blocks and eco-bricks (Ipen, 2019). In 2018, the Global Asset Recovery Purchases team developed several new solutions for plants around the world. They include recovering plastic waste from diaper production in Mexico and converting it into plastic pellets for making products like buckets and brooms . In Canada, the Belleville Plants converts scrap and process waste from feminine care product manufacturing into spill mitigation products.

"There is a double benefit - we create a more circular supply chain by avoiding the landfill while also getting revenue for this would-be waste," the citizenship report of P&G stated. The company found that since 2008, the Zero Manufacturing Waste to Landfill program has helped save the company more than $2 billion or 100 billion pesos and divert more than 5 million tons of waste from landfills.
