Frequently Asked Questions

Which Modesto businesses must recycle under AB 341?
Under § 5-5.154, any business that contracts for solid waste service and generates more than four cubic yards of total solid waste per week must arrange for recycling service, as must any multifamily residential dwelling with five or more units.
How can a covered business comply with Modesto's recycling mandate?
Section 5-5.154(b) allows two paths: source separate recyclable materials and subscribe to a basic recycling collection service (or an authorized self-haul arrangement), or subscribe to an alternative service, like mixed waste processing, that yields diversion results comparable to source separation.
Does a small shop generating little waste have to comply?
Not under § 5-5.154's direct threshold. Businesses generating four cubic yards or less of solid waste per week and not part of a five-or-more-unit multifamily building fall outside the mandatory recycling threshold, though other provisions of Title 5, Chapter 5 still apply to their general waste service.
