RFP # 8894 Page 1 of 10
The City of Denton Solid Waste and Recycling Department is soliciting proposals from qualified
Proposers to enter into a contract for a complete line of Waste Carts, Recycling Carts, Cart Parts
and Related Products. All products offered must be new, unused, latest design, and technology
unless otherwise specified.
As carts and bins are usually exposed to the outdoor elements, all must be able to withstand all
types of outdoor climate to include high heat, consistent rain, humidity, inclement weather and
cold climates.
The intent of this Solicitation is to provide the City of Denton (City) with products to meet its
needs. Therefore, Proposers should demonstrate experience providing the Products and Services
as defined in the RFP.
The top 3 ranked vendors will be required to bring samples so that the City of Denton can Demo
the carts. The samples will be returned after demo is complete. The vendor will be required to
deliver and pickup (at no cost to the City of Denton) to the City of Denton Solid Waste Department
located at 1527 S Mayhill Rd., Denton, TX. Purchasing will set up a date and time for delivery
with the top vendors after evaluations.
Expectations:
All items to be purchased under this contract shall be in accordance with all Federal, State, and
local governmental standards, to include, but not be limited to, those issued by the Occupational
Safety and Health Administration (OSHA), the National Institute of Occupational Safety Hazards
(NIOSH), and the National Fire Protection Association (NFPA).
All carts shall meet, at a minimum, American National Standards Institute (ANSI) cart standards
Z-245.30-196 and Z-245.60-1996, or latest ANSI update. All applicable rules, regulations, laws
and standards pertaining to this product must be adhered to. The following specifications supersede
the standards listed above, where applicable:
i. The cart shall be manufactured from high-density polyethylene (HDPE). The HDPE must
have a density of 0.947 to 0.968 grams cm3. The Melt Index (MI) of HDPE must be, at
minimum, 4.0.
ii. The cart shall have an ultraviolet (UV) inhibitor to prevent deterioration and shattering.
The UV inhibitor shall be added at a minimum of 2% by weight, or technologically
advanced equivalent, thus ensuring maximum protection from the elements. The proposer
must provide documentation to demonstrate how this requirement is met.
iii. The cart shall be manufactured with a smooth non-textured surface and shall have no sharp
edges on the outside.
iv. The cart shall be manufactured free of inside recesses, projections or other obstructions
where refuse could be trapped.

opening.
vi. The cart shall be manufactured with a foot operated tilt feature designed in the axle area to
facilitate easy tipping.

required. The inhibitor shall guarantee effectiveness against sun deterioration or the lid becoming
brittle due to exposure.
The cart section will be furnished with a hinged lid, with the hinge to the rear of wheeled section.
Lids shall be curved or built up to drain and shall be light and stiff for convenient handling. Lids
shall sit flush or overlap the sides but may flare out so they will not bind against the sides if the

bars and lids. However, this action will in no way waive the warranty requirement of the
carts/recycling bins. All carts that are identified as not repairable, as determined by the
