ITEM EXPLANATION:
Source reduction and recycling have been mandated by AB 939 and the Mi
Recycling ordinance, and embraced by Carlsbad residents as a way of life. The
yard waste curbside collection program has been successfully implementec
diverting approximately 20% of the single-family residential wastestream.
sponsored home composting program would supplement the curbside program,
to achieve AB 939 diversion goals of 25% by 1995 and 50% by 2000.

Curbside collection of yard waste requires separate routes and trucks, and di-
much yard waste from the curb as possible will reduce collection, transport;
disposal costs. Moreover, the San Marcos Landfill is experiencing a surplt

In the fall of last year, staff obtained five sample composters. Subsc
additional sample was obtained. A notice was placed in the City Manager'
offering these samples to employees who are also residents of Carlsbad, in e
their feedback. All five cornposters were placed. Over the course of the
the participants lost interest and their composters were transferred to othe
residents. Two participants have utilized their composters faithfiillj
participant has utilized the composter sporadically. The recently acquired
and the two transferred cornposters are currently being used.
AU participants offered their feedback to staff on criteria that they considere
in a composthg unit. Staff has compiled this feedback, and developed d
criterion to select a composter for mass distribution.
Enclosure:
An enclosed composter allows the composting of kitchen scraps without roc
into the pile. The ability to compost kitchen scraps is important becam

recommends selecting one composting unit for the proposed program.
Findings:
The six composters tested were the Soilsaver, the Green Magic Tumbler, thf
the Seattle Cornposter, the Presto, and the Earth Machine. Staff has evali products based on the above criteria. The Presto is not enclosed, and t
eliminated. The Green Magic Tumbler utilizes the batch process. The Bic
the Seattle Composter do not allow for easy harvesting.
The remaining two composting units, the Soilsaver and the Earth Machin
priced the same ($40 plus tax). However, the Earth Machine is easier to a
available unpackaged (consistent with source reduction goals), and is madt
post-consumer and 10% post-industrial plastic. The Soilsaver is made of
industrial plastic. Additionally, the price of the Earth Machine includes
