There is an interesting point, which my hon. Friend may want to tease out of the Minister. Has a model been produced to assess the effectiveness and efficiency of that scheme? An earlier amendment referred to providing composters to householders and raised the issue of whether that might not be an appropriate way of encouraging the proper and responsible treatment of waste. I worry slightly that the alternative of providing a facility where people can have materials composted for them is less effective. It will certainly mean more journeys, and it will be a bigger process. If things are dealt with on site, they will obviously be dealt with more quickly and efficiently. Have the Department or the Minister produced a model to assess the scheme?
