Problem: As technology becomes more and more accessible to people across the world, so does the increasing problem of where to throw away all that e-waste. There were some 50 million metric tons of e-waste produced in 2018 and that number is expected to grow to 120 million metric tons by 2050.
Solution: Since all that e-waste has some inherit value to it, it'd be great if a service existed that filtered out all the precious materials (metals, gold, silver) and either re-used that material or sold it for a profit. For context, Waste Management (an American waste management, comprehensive waste, and environmental services company) has a current market capitalization of 46.25 billion US dollars.
Monetization: Since most people are going to throw these electronics away, it'd be fairly easy to develop a service that picks up -- either weekly/bi-weekly/monthly/etc. -- e-waste from each "subscribers" home at no cost. Once all the e-waste is collected, you can then have some automated system that filters out all the profitable material. The rest of the material can be recycled.
