The lifecycle carbon footprint for a half litre of small pack bottled water is 111 grams CO 2 equivalent. [35] By comparison, the same sized PET plastic-bottled soft drink produces 240 grams CO 2 equivalent. Soft drink bottles require much thicker plastic due to carbonation, and therefore many more grams of CO 2 equivalent.

This will not entirely replace their production of plastic bottles. [24] Whether this is environmentally beneficial can be argued: aluminum is more often and more efficiently recycled, but producing one aluminum can produce 1,300g carbon dioxide emissions, which is much more than the 330g it takes to produce one plastic bottle of the same size ...
Some people foresee a true sustainable steady state economy that may be very different from today's: greatly reduced energy usage, minimal ecological footprint, fewer consumer packaged goods, local purchasing with short food supply chains, little processed foods, etc. [40] [41] [42] Less packaging would be needed in a sustainable carbon neutral ...
Singapore: plastic bottles are collected with glass bottles. The stream in which PET bottles are collected comprises PET bottles, other plastic bottles and glass bottles, and contamination. Switzerland: Retailers contribute a fee to a national operator (PRS) who manages collection bins, sorting and production of rPET flake.
The strongest bottle candidates for ecobricks are thick and durable plastic bottles with wider cap openings that can resist UV radiation. [5] Any size of transparent polyethylene terephthalate (PET) plastic bottle can be used to make an ecobrick. The bottle and the packed plastic are clean and dry to prevent the growth of bacteria.
The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
This re-usable carrier bag has been made from recycled plastic bottles. It is an example of open-loop recycling. In open-loop recycling, also known as secondary recycling, or downcycling, the quality of the plastic is reduced each time it is recycled, so that the material eventually becomes unrecyclable. It is the most common type. [98]
