Recycle what you can and burn the rest. That is the most ecological solution if it is done by modern standards. It works and is done in most of Europe.

Germany, Switzerland, Belgium, Japan, Netherlands, Sweden, Denmark, Norway and Austria all put less than 5% of their trash directly into landfills.

Functioning trash handling is far more effective at reducing the ecological impact of plastic than any attempt to reduce plastic consumption.

Personaly I think Switzerland is the best model on how to handle trash properly.
