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 ...
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.
An ecobrick is a plastic bottle densely packed with used plastic to create a reusable building block that achieves plastic sequestration.The concept behind ecobricks is to utilize and upcycle post consumer plastic, benefiting our Earth. These plastic bottles are precisely packed with clean and dry used plastic to avoid the growth of bacteria. [1]
There is also much debate about the total carbon, fossil fuel and water usage in manufacturing biodegradable bioplastics from natural materials and whether they are a negative impact to human food supply. To make 1 kg (2.2 lb) of polylactic acid, the most common commercially available compostable plastic, 2.65 kg (5.8 lb) of corn is required. [57]
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 ...

Plastic sequestration is a means of plastic waste management that secures used plastic out of industry and out of the environment into reusable building blocks made by manual compaction. Plastic sequestration is motivated by environmental protection and modeled on the Earth's process of carbon sequestration. [1]
