Insulation mats made form recycled PET bottles are already commercially available. They are very effective e.g. as geyser blankets or as roof insulation, are easy to install and pose no health threat.
Since we covered our geysers with PET-fibre blankets, the electricity consumption dropped by 15% (P. Steiner)
Put it simply: Carbon sequestration is about capturing CO2 that is emitted as a result of burning fossil fuels (e.g. oil, coal or gas) and storing it underground (for ever), thus lowering the CO2 levels and reducing global warming. For a more detailed explanation, have a look at wikipedia, where you will also find a concept of how a biomass business, like ours, can contribute to a negative CO2 footprint.
Furfural is made from 100% Natural Carbon
Hemicellulose, is also the second most-abundant organic material in nature, typically representing 25–35% of lignocellulose by mass.
Furfural and Carbon Capture, Storage & Energy Savings
Furfural is a versatile chemical building block that is made from plant carbon. Therefore, any material that is made from furfural and that lasts 'forever', is a form of carbon storage. Using such materials to reduce (domestic) electricity consumption, will further reduce CO2 emission, where gas or coal-fired power-stations are used to generate the electricity that is used for heating or cooling a house.
The pathway from furfural to PET is explained in our "a truly biobased TPA for PET" article ( May 2015).
