The World’s First Fully
Recyclable PCB Substrate.

Jiva has developed a patented, competitively priced and fully recyclable PCB substrate – Soluboard®. As the world becomes more connected, Printed Circuit Boards or PCBs are becoming ever more present inside our products.

The Summary.

18 billion square metres of PCBs are manufactured every year and the rising value of the precious metals within PCBs means that efficient recycling is a necessity.

The organic structure of Soluboard® means the non-toxic ingredients delaminate in hot water. This allows the electronic components to be removed efficiently for re-processing.

Founded in September 2017, Jiva secured a pre-seed investment from the Royal College of Art and Venrex Investment Management LLP and was accepted into the InnovationRCA incubator.

Jiva has now raised over
£1 million in funding and we are operating as a team of four from our Finsbury Circus head quarters in London.

The Problem.

On a global scale, it is estimated that over 50 million tonnes of Waste Electrical and Electronic Equipment (WEEE) is produced every year. (source: WEF)

This number shows no sign of decreasing and the UK alone contributes an average of 2 million tonnes to the fastest growing waste stream every year. (source: HSE)

The current substrate used in the PCB industry is constructed from epoxy resin and fibreglass; this means that the only commercial method of processing waste PCBs involves shredding and incinerating them to extract the precious metals within. This inefficient process is very energy intensive and results in a substantial loss of value of any precious metals recovered.


The time that this recycling process would take combined with the minimal financial gain means that PCBs are very often not even removed from products by waste handlers; this results in the precious metals within the PCBs not being recovered as the waste metals that are easier to process are prioritised.

High numbers of electronic waste are illegally exported out of Europe in order to avoid processing it. It is estimated that only 20% of European e-waste is properly tracked for collection and recycling, (source: WEF) resulting in over 17,500 shipping containers of e-waste being illegally exported from the EU every year.

The Solution.

Patent protected, Soluboard® is an alternative to the market leading material used within the PCB industry: FR-4. Soluboard® is a competitively priced, fully-biodegradable material that is able to rival the outdated fibreglass and epoxy alternative.

The primary ingredient in Soluboard® is flax which has a much smaller carbon footprint than the alternative glass-based fibres. The flax is formed into the multilayer bio-composite structure of Soluboard®, giving the material strong mechanical and high performing electrical properties.

The organic structure of Soluboard® means the non-toxic ingredients delaminate when immersed into hot water. This allows the organic fibres to be composted the water to be disposed of using standard domestic waste water systems and the electronic components to be recycled.


By introducing a water-based recycling process, carbon emissions will be greatly reduced and the recycling industry would see higher yields of precious metal recovery if Soluboard® became widely adopted.

aIt has been estimated that 10.5kg of carbon per square metre of Soluboard® PCB would be saved in comparison with an FR-4 PCB – this would suggest a 60% reduction in a carbon footprint if Soluboard® was successfully integrated into a PCB supply chain.

Soluboard® would have the most significant impact if integrated into the supply chain of customers who already offer take-back schemes or operate within the circular economy. This will therefore allow the manufacturers of the products to sell their old products to electronic waste handlers at a higher price and therefore subsidise the costs of WEEE disposal.
