Honestly I look forward to that. It's a big improvement over using fossil fuels for energy — combine it with landfilling, and you're just re-burying oil after some transportation and manufacturing. And it gives a softer landing to the petroleum industry.
Over time we can replace petro-plastics with more sustainable materials. Bioplastics? Incineration-recycling, where you capture the CO2 and turn it back into plastic feedstock?
Edit: Also I think composting cardboard and paper would be great.
The problem in this specific case isn't necessarily just in the net benefits of fossil fuels but instead in how the benefits and their associated costs are distributed.
I'm certain that the profits of the MNCs pushing this will not remain in Kenya. Yet the pollution and its consequent financial/non-financial costs most certainly will.
