In 1991, the steel industry in Japan recycled its by-products as follows: almost 100% of blast furnace slag, 89% of converter slag, and 84% of electric furnace slag is used for construction and infrastructure purposes.
In the Philippines, a coconut beverage producer buys 50% of the waste coconut water produced by a desiccated coconut processing firm, and uses it as raw material. Both parties benefit significantly from this industrial waste exchange venture.
