Symphony Environmental Technologies forecast a large rise in profit amid an expected 17.6% bump in revenue.
The company said it has continued to increase sales of its d2w oxo-biodegradable plastic additives in several of its markets, including in South America and the Far East.
Momentum, however, was most apparent in the Middle East, and in particular Saudi Arabia, where legislation requires the use of oxo-biodegradable technology for everyday plastic items.
Revenue for the year through December is expected to reach £8.0m, up from £6.8m in 2016.
Pre-tax profit is expected to jump to no less than £350,000, from £123,000 in 2016, partly owing to the group's operational gearing position.
