Mayor Ballard made people nervous again last week when he dumped Lisa Laflin, the city’s recycling coordinator. They wondered if the city’s deplorably miniscule recycling effort wasn’t about to get the ax. After all, curbside recycling only has a 3 percent participation rate. Not to worry, says the Mayor’s Office, we now have an Office of Sustainability to actually expand the city’s green options. Details should be released in the next few weeks.
