Each year the world generates two billion tonnes of solid waste. Not even 50% of this waste is recycled, resulting in billions of tonnes disposed of in our oceans. Already some marine scientists claim that this waste has already killed off over 90% of marine life. How can we save our planet by moving the world toward 100% verifiable recycling? Brice and Misha will discuss how the blockchain decentralized ledger architecture is being used to enable recycling by ensuring that each stakeholder is accountable for recycling shipping waste. This discussion will share the architecture of blockchain, the properties of this architecture, how it is used to deliver value, and the lessons that we learned from building a real blockchain recycling supply chain. Finally, we will explore other areas where blockchain will enable things like carbon tracking to combat climate change and other sustainable supply chain applications.
