Yes, send them to landfill. The biodegradable bit is a bit disingenuous; it salves the feelings of the supermarket who think they are doing a Good Thing.
The bags biodegrade efficiently in anaerobic conditions over time. That is they biodegrade in landfill. My Council who take compost making seriously ask us not to put biodegradable bags in the food waste. Get yourself paper bags or use newspaper to wrap the waste. But please if you have a food waste collection do not put food waste into landfill.
