John Sylvan is the inventor of the K-Cup coffee brewing system. Despite its overwhelming success as a product he regrets ever doing so. He left Keurig long ago and now runs a solar energy company.
You can overcome some of the waste by getting a reusable cup and filling it with your own coffee (there are even workarounds for the new DRM’d cups). The downside is the mess the grounds make but they’re also recyclable so it works out.
