Set up furnace boilers to incinerate the office waste including papers and then use steam turbines to generate Electricity. Waste incineration can be done at each Federal complex like it is already being done at hospitals.
This becomes a local supply of electricity that is self contained (and thus ideally unaffected by power grid meltdowns, terrorism acts, storms and blackouts). The office buildings can use it for consumption or sold to the power companies. Incinerate papers un-shredded as well as the daily litter at our workplaces, cafeterias and yards. Being already done in Fairfax County, Virginia
For now they end up in landfills someplace far away, ‘shredded’ or otherwise.
