It is time for some zero based evaluation of the philosophy that mandates this waste. The so-called dump site crisis, like many of the chain jerks we suffer, never was. LA has available a receptacle for the next 50 years in the abandoned Iron Mountain diggings. Groundwater contamination is a concern only where that aquifer is is a usable source. Biodegradability is a so what quantity. The pottery shards from 5ooo years ago did not biodegrade but so what; Civilization continues.
Like many, perhaps most of the feelgood restrictions on personal freedom of action, the time for compliance is given no value. In 3rd world countries, dump scavenging is a way of subsistence life - all we get for the effort dividing our waste is the feelgood of the fooled.
