MULCH COLORANT SPECIFICATIONS
SCOPE OF WORK
RFP #7438‐Mulch Colorant
INTRODUCTION
Since 2003 the city of Denton Beneficial Reuse Department has provided deco‐colored mulches
for sale to the public. To produce our line of deco‐colored mulches we blend recycled
hardwoods with a long‐lasting and environmentally safe colorant in either brown, red, or black.
Proponents of our colored mulches appreciate the vibrancy it brings to their landscapes and are
pleased with the ability to choose from the various colors.
For this reason, the City of Denton is soliciting bids to establish an annual contract for the
purchase of colorant to be applied to the various ground wood mulch products in support of
the city’s compost operation.
HISTORICAL DATA
Historical totals of mulch production were approximately 1,765 cubic yards of black mulch,
2,875 cubic yards of brown mulch, and 705 cubic yards of red mulch for the 18‐19 fiscal year.
Usage varies based on mulch sales, which are dependent on numerous factors.
REQUIREMENTS
Colorant must be available in three colors: black, red, and dark Brown.
Colorant must be liquid, available in 55‐gallon drums.
Colorant must be environmentally safe for people, plants, and pets.
Colorant must be compatible with city’s equipment, including a mulch color jet machine and
628 McCloskey screener.
Supplier must provide mixing instructions for their brand colorant in the form of a user manual.
Written documentation on how to set up the machine specific to each color is required.
All product must be shipped and received within 7 business days from time of order.
Colorant must be available to purchase per pound.
Samples may be required for evaluation. Upon request, samples must be provided to the City
within five business days. Failure to provide samples and related documentation in a timely
fashion may be grounds for deeming the bid nonresponsive to specifications.
