Nuclear Waste Storage

Category: Nuclear Industry

The UK alone will generate a volume of radioactive waste over the next century that would fill Wembley stadium. Increasingly the material considered to be the safest and most stable in which to house this incredibly hazardous and long-lived waste is glass (typically borosilicate glass). Why glass? Because it’s chemically highly durable and radiation-tolerant; and glass’s amazingly flexible structure will incorporate the many chemical elements of radioactive waste and bind them within that structure so it is very difficult for them to dissolve out.

The Good Taste of Beer

Category: Container Glass

In 1976, Owens-Illinois (now O-I Glass) the world’s leading manufacturer of food and beverage container glass (and still is) helped run an ad campaign in the US entitled “The Good Taste of Beer”. It promoted the merits of enjoying beer from a glass bottle: “glass is class”. This message stands the test of time. Glass beer bottles have an all-natural composition of limestone, silica sand and soda ash, which make the bottles tough and virtually inert. The glass doesn’t interact with the beer inside, meaning you’ll enjoy it the way the brewer intended.

One green bottle

Category: Sustainability

That green bottle is enjoyed once but it’s likely to be made from ~70% cullet (recycled glass for re-melt). The percentage could be so much higher …. the industry’s target is 90% by 2030. Achieving more and better-quality cullet (ie colour-separated and contamination-free) is essential for reducing carbon emissions in the furnace when making new glass bottles and jars, as well as reducing dependence on natural resources. For every tonne of glass recycled, the industry saves 580kg of CO₂ – enough energy to charge 74,000 smart phones. As householders, we all have commitments to recycling glass, and 30% of us recycled more glass during lock-down (more time/more wine!) but we can all ask ourselves “could we do more?”
