He kept the new bins’ wastebasket attachments small, about the size of a milk jug, to motivate people to recycle more so they wouldn’t fill up their wastebasket space.
The City of Cambridge gave the Institute an “Environmentally Desirable Practice” award and bestowed on Sandberg a plaque made from recyclable plastic to recognize his efforts to “green the Crimson.”
Colleagues said Sandberg had planned to continue strengthening Radcliffe’s environmental awareness. He recently added batteries and disks to the list of items Institute employees should recycle. He also started initiatives at the Institute for purchasing recyclable products and donating employees’ used clothes to local charities.
Institute staff say they plan to carry on Sandberg’s environmental work.
“He worked very hard on the recycling program and as a tribute to him we will definitely continue his efforts,” said David Butler, the Institute’s building services manager.
Sandberg is survived by his wife Rona and his daughter Jessica.
A memorial service will be held today at the First Parish Unitarian-Universalist Church at 1 p.m.
