The point is to change processes and habits so the entire sum of resources used and pollution produced is minimal. Reuse is almost always better, so maybe yoghurts can come in glass jars instead of tiny, hard to wash plastic cups? Maybe smallest containers, that discourage reuse should be taxed extra? Much easier to wash 1l yoghurt cup than 4 x 250ml. Biodegradable - that's cool, but sometimes they can be toxic, not really biodegradable or require a lot of resources to produce, and a lot of waste is produced as by product. Sorting is great, but only recycling, which requires cleaning - which is attacking the problem from the wrong end.
