Given the convenience of single-use cups, PyroCup aims to reinvent what we now know as the takeaway cup. PyroCup has steered away from the conventional cup and uses a laminated cup design comprised of paperboard, plastic and aluminium - much like laminated cartons manufactured by the Swedish company, Tetra Pak. The design of these cups will allow for a cradle-to-cradle approach whereby the cups can be recycled using a process called Pyrolysis; hence the concept name 'Pyro' + Cup.
As seen in the diagrams provided, Pyrolysis largely is a recycling process that uses polylaminate mixtures separated from the cup paper fibres to evaporate plastic, leaving raw, recycled aluminium which is more valuable than aluminium oxide. This is done by heating the mixture to 400° in an oxygen-free chamber, to which the un-oxidised aluminium can then be used in the manufacturing process to produce new cups. As raw aluminium can be recycled multiple times and in doing so actually takes up 95% less energy, Pyrolysis makes the recycling of the PyroCup not only valuable and worthwhile but aids in using renewable, green energy in an effort to make this process as carbon neutral as possible.
The PyroCup itself, as seen in the diagram above, is created largely through compounding fibres derived from harvested logs and uses molten polythene to prevent leaking. Given a portion of the fibres are bleached white, businesses like Starbucks and McDonalds will still be able to print their branding on the PyroCup to ensure brand awareness.
In order to distribute on a global scale, PyroCup can partner with organisations who are already trailing this technology. These organisations include Alucha, an innovative recycling company based in Barcelona; and Enval, an English organisation that focus on microwave pyrolysis.
