Great week working with young people at #EDSCIFEST at Dynamic Earth. A chance to examine one of the most common litter items and common forms of plastic PET [Polyethylene terephthalate] that ends up in our seas.
Visitors joined me to calculate how much energy (petrol) we can save by recycling plastic bottle. Bottles weighed 11 – 45 grams and using an Embodied Energy formula for PET we calculated that the energy value of 100 bottles each weighing 30 grams would contain the energy/petrol equivalent to travel 84 km in a small car, or 385 calories, enough energy to walk 7km. Thought provoking images and values to share and make us all determined to make sure we don’t drop but recycle all our bottles. Thanks to everyone who attended, donated bottles and helped out with the event. Looking forward to bringing all the #LitterCUBES to #EDSCIFEST 2020.
