How green can your loo roll be? Lots of companies have sprung up offering what they say are the most eco-friendly ways to wipe - and there's a lot to think about.

Listener Barbara buys recycled toilet paper - and wants to know if she's better off buying one of the bamboo options on the market. Jo already buys bamboo but is curious about the difference packaging and delivery options make.

To get them some answers, Greg Foot speaks to Shanta Bhavnani from Ethical Consumer magazine, who carried out its 2023 ethical toilet paper guide, and materials expert Dr Eral Bele of University College London, who's studied the properties of bamboo.
