Danish Brewer Carlsberg Is Working On “Paper Bottle” Prototypes

To reduce the use of plastic bottles, Danish brewing giant Carlsberg is working on two prototypes for “paper bottles”. In an announcement made during the C40 World Mayors Summit in Copenhagen on Friday, October 11, the company said its “Green Fibre Bottle” prototypes were produced from sustainably sourced wood fibres and “fully recyclable.”

To make sure these “paper bottles” can hold beer, the prototypes use an “inner barrier”. One prototype uses a recycled polyethylene terephthalate polymer film barrier, which acts as a thin internal lining. The other uses what Carlsberg described as a “100% bio-based” polyethylene furanoate polymer film barrier.

According to the company, they are pleased with the progress although some remaining technical challenges need to be overcome. The ultimate goal is to produce a 100% bio-based bottle without polymers that can be brought to market.

Carlsberg is one of many major international firms looking to change the way it packages products. Earlier this week Unilever, whose brands include Dove, Ben & Jerry’s and Lipton, said it would halve its use of virgin plastic by 2025.


Prototype System Uses Algae To Sequester Carbon Dioxide

A new company, Hypergiant Industries of Texas, has created a prototype of what it calls an Eos Bioreactor. This Bioreactor uses A.I. to capture and sequester carbon from the atmosphere using algae.

The prototype bioreactor is 3′ x 3′ x 3′ and holds 55 gallons of water and algae. “Algae wants CO2 and light,” the company explains on its website. The system uses an artificial light source. The algae and water are pumped through a series of tubes to maximize their exposure to light sources lining the inside of the Reactor.”

Inside the reactor, the algae absorb the carbon dioxide and in the process creates biomass, essentially dried algae. The company says the algae biomass can then be “harvested and processed to create fuel, oils, nutrient-rich high-protein food sources, fertilizers, plastics, cosmetics, and more.”

Currently, the company doesn’t have a timeframe when the product will begin selling. Next year the company plans to make and design algae boxes open-source and see what the world will make of them.
