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 ...
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 ...
A plastic is considered biodegradable if it can degrade into water, carbon dioxide, and biomass in a given time frame (dependent on different standards). Thus, the terms are not synonymous. Not all bioplastics are biodegradable. [44] An example of a non-biodegradable bioplastic is bio-based PET. PET is a petrochemical plastic, derived from ...
Polymer degradation is the reduction in the physical properties of a polymer, such as strength, caused by changes in its chemical composition.Polymers and particularly plastics are subject to degradation at all stages of their product life cycle, including during their initial processing, use, disposal into the environment and recycling.

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.
A carbon footprint (or greenhouse gas footprint) is a calculated value or index that makes it possible to compare the total amount of greenhouse gases that an activity, product, company or country adds to the atmosphere. Carbon footprints are usually reported in tonnes of emissions (CO 2-equivalent) per unit of comparison.
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 ...
Life cycle assessment (LCA) is sometimes referred to synonymously as life cycle analysis in the scholarly and agency report literatures. [7] [1] [8] Also, due to the general nature of an LCA study of examining the life cycle impacts from raw material extraction (cradle) through disposal (grave), it is sometimes referred to as "cradle-to-grave analysis".
