Gymea Technology High School and Sylvania High School will each receive $2500 in eco-grants under the State Government's environmental trust program.

Miranda MP Barry Collier said a project called Fostering Native Flora and Fauna to Flourish had won a grant for the Gymea school.

"This project encourages students to become environmental stewards of their own area by returning part of the school grounds to a more natural state and promoting the return of native fauna,'' he said.

The other project awarded with a grant was Sylvania High School's Eco Rangers Wiping Out Waste.

"It aims to reduce food-scrap waste in school kitchens and the canteen by composting food scraps, growing herbs and vegetables and using fertiliser from a worm farm,'' he said.

Mr Collier said competition for the grants was intense.
