Abundance is currently offering savers the opportunity to invest in CoGen Limited, which uses a new technology called ‘gasification’.

Rather than incinerating waste, this process takes waste that cannot be recycled and would be taken to a landfill and converts it back into its original constituent elements, which can then be recovered and reused. The process creates electricity and heat for other uses.

The investment is via a debenture, which is a tradeable form of corporate bond, in CoGen Limited. The project offers investors a 10% annual fixed return over a period of four years and six months.

So far, investors have committed £2.9m to CoGen – which is close to the minimum investment it was seeking to guarantee the project will go ahead. It is hoping to raise £7m in total.

Savers can allocate all or some of their £20,000 annual tax-free ISA allowance to an IFISA, which allows investors to make money from their peer-to-peer loan investments tax-free.

Abundance works with businesses, the government and the financial services industry to provide funding to new infrastructure projects. Investors who open an IFISA with Abundance can invest in other projects available on the platform, and gain exposure to projects that investors are selling their holdings in via the secondary market.

While the returns are attractive, particularly in comparison to the interest that is available via a typical cash ISA, it is worth noting that these investments carry higher risks. Investors may not receive their capital back and these investments are not covered by the Financial Services Compensation Scheme.
