Lexington’s proposed garbage policies are great for rats and bad for public health.
Free garbage pickup started as a public health measure to reduce the rat and flea populations that spread disease. Lexington proposes to charge more to anyone with excess garbage, and to sell garbage bags for pickup and disposal of garbage over a set amount. Steel garbage cans were developed to keep the rats out–serving rats lunch in bags is a bad idea.
Charging for excess garbage will result in more garbage on roads, in the woods, and in public trash cans. High taxes at a minimum should assure policies designed to minimize rats and other public health problems; thus, free garbage pickup should be a high priority.

About half of Massachusetts communities already charge for garbage pickup, including Arlington and Concord. Some towns, like Winchester, don’t provide public garbage pickup at all; you either use a private contractor or bring your trash to the transfer station. Is Winchester a rat-infested hellscape?
If you don’t want rats at your house, you can use Lexington’s FREE curbside compost service for anything rats can eat. If you’re going to waste your neighbor’s tax money sending food waste to the incinerator, you will pay for the privilege.
This is the only paean to steel trash cans that I’ve heard over the course of this entire discussion. Anyway, I can’t speak to the history of other places, but I don’t believe free trash collection started in Lexington for public health reasons. After all, the town had “free” trash disposal (at the dump) for half a century before curbside pickup was introduced. As best I can tell, the collection service was developed in response to the closure of the dump.
