OK, two things. First, waste collection is run by your local authority, not the government.
Second, you haven't read the story properly. It's writing up two separate reports, one of which was commissioned by the government which has found that there wouldn't be health hazard if rubbish were collected less regularly. We can debate that separately in a minute.
The second report points the rather amazing level of waste in food.
Neither of these are even remotely about policy. They're reports, one of which throws up some slightly iconoclastic thinking. So the government is not about to end weekly waste collection (actually, my council does two regular rubbish collections and one recycling collection a week). It's always a good idea to read beyond the top line before forming an opinion.
