Mayor Mufi Hannemann will be on Windward O'ahu today to gather input to develop a sustainable recycling system.

The session, part of a series, will be from 7 to 8:30 p.m. at Windward Community College.

Seattle-based consultant R.W. Beck will present data on O'ahu's waste composition, a cost and benefit analysis of various curbside recycling options and the comparative benefits of recycling and waste-to-energy.

The city is ready to present various collection scenarios and their costs to the public while asking for constructive input, the mayor said in a press release.
