Plastic is a material that can sit in a landfill for 500 years, it should only be used where you need a _long_ term application that also requires a weight/shape/durability that is not easily manufacturered with other materials. A yogurt container will have a typical 15 to 30 days shelf life, this is not a good use of plastic, it also interacts with an acidic medium (Which absolutely breaks down a fraction of the plastic structure). It really should always be made of glass, the only reason it isn't so is purely cost driven. Coca-Cola, Nestle, Pepsico, Procter&Gamble, Danone, Mars have all pretty much externalized the huge environmental cost of plastic and reduced their operational costs at ours and our environments expense. We are damaging ourselves and our waterways for the sake of an illusionary convenience and the profit margins of a few giants. Glass recycling is also energy intensive but it doesn't even have be recycled, people need to stop being disgusted and go the same way as beer bottles. Glass can be high power washed or autoclaved and reused by the manufacturer. Glass transportation costs also become marginal once we transition to EV logistics delivery in the next 15/20 years.
