I'd love to make companies pay for their products' entire lifecycle, including disposal and cleanup. It's not right that a company can manufacture future-trash, sell it, and then absolve itself of the negative externality when the customer throws the product away and off it goes into a landfill.

If a company's process produces waste, it should bear the entire cost of leaving the environment the way they found it rather than just pumping the waste into it. If a company's products are not reused, it should bear the cost of taking the used product back and restoring the world to the way it was before the product was built.
