This start-up makes recycling household batteries as easy as possible

The Better Battery Company sells batteries in special packaging. Its batteries are white at the positive end and blue at the negative. Inside the box, the batteries are arranged in rows with the white end upturned. When each battery runs out, you put it back in the box the other way up so it’s easy to see which are used and which are new. When the box is filled with spent batteries, you return it using a free postage label and the Better Battery Company sends them off to be recycled.
