The Public Utilities Board recommends approval (5-0).
Body
FILE INFORMATION
The City of Denton Solid Waste and Recycling Department began mining an old landfill cell during the spring of 2016. The purchase of the sorting station, trommel, mobile slow-speed shredder and a mobile horizontal high speed grinder will enable staff to process commodities that will be recovered during the approved mining operations, along with building materials recovery (BMR) processing operations to meet State and local recycling and waste diversion goals. This equipment will assist in the recovery of different commodities including wood, cardboard, metal, plastics, various bulky items, mattresses, yard trimmings, commercial and demolition (C&D) materials and various materials recovered from the operations. This operation will be conducted in phases with additional equipment scheduled for acquisition in the next five (5) years. An equipment schedule showing the breakdown of equipment is included as Exhibit 1.
The trommel will be used to separate the dirt from the municipal solid waste that will be excavated during the mining operation. Once the material is processed through the trommel it will be conveyed onto the sorting station where staff will separate the recyclables into different roll off containers placed directly below the equipment. In 2016, staff received a $200,000 grant from North Central Texas Council of Governments (NCTCOG), to provide partial funding to purchase a mobile slow-speed shredder and a mobile high speed grinder which will enable the Solid Waste and Recycling Department to achieve greater efficiencies and materials reduction in processing mattresses, various bulky items, yard trimmings and C&D materials. The shredder will separate recyclable materials in mattresses and various bulky items to facilitate their recovery. These materials include interior metal springs, cotton fibers and wood. The metal will be recycled through the local commodity market, cotton fibers will be used for bio-reactor feedstock, and the wood will be further processed with the high speed grinder to a 4” minus material to be used for compost or fuel feedstock. The high speed grinder will process yard trimmings and various C&D material that are collected during the BMR and mining operations. The processed material will be used in various applications such as erosion control materials, mulch product production for retail and wholesale marketing and feedstock for the composting operation.
The City of Denton Solid Waste and Recycling Department will fund the non-grant funded portion of the costs to purchase and deliver the shredder and grinder using Solid Waste & Recycling bond funding.
Request for Proposals were sent to 48 prospective suppliers. In addition, specifications were placed on the Purchasing website for prospective suppliers to download. Nine proposals were received but some vendors did not provide pricing for all four items. Proposals were evaluated based upon published criteria, including price, delivery, compliance with specifications, and probable performance by the supplier. Each of the four pieces of equipment was evaluated and scored separately by a committee comprised of Solid Waste, Fleet and Purchasing staff. The committee recommends award of the equipment to the vendors shown on Exhibit 2 as providing the best value for the City. Exhibit 1 does not include vendors that did not provide pricing for that specific item. The lower priced vendors shown for the Item 2-Trommel did not meet specifications that are required by the existing landfill mining permit. For Item 3-Slow Speed Shredder and Item 4-Grinder, the low bid machines did not meet the minimum horsepower specifications required by the mining operation.
