- Two construction materials industries J&J cement and B&B Bitumen are situated side by side. Each year, B&B bitumen purchases about 501 tonnes of lime kiln dusts produced by J&J cement to use as filler in bitumen at $10/tonne. This avoids B&B Bitumen to purchase 455 tonnes hydrated lime per year for filler materials. The market price of hydrated lime is 40/tonne. What is the annual economic benefit of B&B Bitumen from this industrial symbiotic relationship?(Dont write $ sign. Just write the whole number what you get, dont covert to kilo or million.
