MIDDLETON, Mass. (AP) — Down the back stairs of the clubhouse kitchen, on a plot lost among the expanse of tightly trimmed fairways and greens, weeks-old food is buried under a tarp and mulch and left to decompose.

But this private country club in Massachusetts isn’t taking an unsanitary shortcut with its trash. It’s trying bokashi, an obscure composting method it says will help it recycle 4 tons of food waste each year.
