After a lifetime of recycling, composting, turning down the thermostat and trying to eat local organic food, some people might not want to leave their bodies to be filled with a chemical preservative and buried in steel and concrete, or even cremated in a gas-fired furnace.

Now they have a couple more options.

Maine's two green cemeteries # natural burial grounds that don't allow embalming or steel caskets # are open for business. And they're getting some.

"We have sold cemetery plots," said Peter McHugh, owner of Cedar Brook Burial Ground in Limington. "I'm in no rush to do burials."

McHugh has sold four plots since last fall, he said. The buyers, who probably are in no rush either, are from around southern and coastal Maine.

He also figures he's had 90 other inquiries from around the state and the northeast. Although Maine has two active green cemeteries, there are only about 10 nationwide.
