David Seymour's new school lunch programme has opened up more concerns - this time from environmentalists. 

The new lunches are expected to come in aluminium trays and non-compostable packaging, prompting worry about sustainability, with some suggesting the food should come in less 'wasteful' packaging.

Ecoware co-founder James Calver has raised concerns about the lack of recyclable materials to be found - and he thinks the sustainability aspect is worth discussing.
