* Amanda Forsyth, manager of the Standard Life UK Ethical Fund, holds a number of newly listed companies in her portfolio, which she says are at the forefront of environmental technology. Symphony Plastics makes biodegradable plastic, which is successfully used in supermarket shopping bags. The company is enjoying strong demand from Irish supermarkets in particular, which receive tax incentives for using the environmentally friendly bags.

Another is Virotec, which has developed a product based on red mud to treat contaminated water. This is particularly useful in regenerating mining sites, but the product also has more far reaching demand, Ms Forsyth says.
