A. How many takeaway meals were consumed over the course of the games?
B. How much waste to landfill were Olympics organisers expecting to have to go to landfill?
8.5 thousand tonnes
C. How many pieces of packaging were needed for the games?
120 million pieces of packaging.
D. Take a moment to look around their site further. How many stages are there in their ‘closed loop’ system? What happens at each stage?
There are 5 stages in their closed loop system.
E. Look further around their site. LBP use a range of’ materials 7 what are bioplastics?Is there anything that can explain further the oil and carbon savings?
These are plastics made from plants. The starch contained within the plant is processed to produce a polymer. It is actually possible to produce most polymers from bio materials, but the bio plastics London Bio Packaging uses most commonly are Ingeo™ PLA (Poly-Lactic Acid) and Mater-Bi®.
F. What is PSM and what are it’s key properties?
Plant Starch Material (PSM) is a flexible bio based packaging material which has not been refined into a bio-plastic. It is made from renewable crops like corn or potatoes. PSM is heat resistant making it particularly suitable for hot food applications and ideal for bio disposable cutlery.
G. What is sugar bagasse and how might it be turned into packaging?
The waste material produced once sugar cane has been harvested for the sugar syrup is called bagasse. This material is a renewable resource. There is not currently adequate information on its effect on carbon emissions, but as this is a waste product, it will by definition be saving carbon as it replaces what would otherwise be a requirement for some virgin material manufacture.
Sugar bagasse is turned into packaging products from its raw form using a process of heating, pulping and then pressurised moulding. These are heat resistant and microwaveable making them ideal as hot food containers and best of all, naturally compostable.
H. Pick one other material listed and explain what it is and what it’s key properties and considerations are.
Recycled Plastic – rPET (recycled polyethylene terephthalate) is the most common plastic that is being recycled back into primary applications (i.e. bottles recycled back into bottles and not ‘down-cycled’ into lesser products like park furniture). Recycled plastics reduce the amount of fossil fuel resources, have a lower carbon footprint than virgin plastics, divert material from landfill and can themselves be recycled.
