How it's made...Colored Landscape Mulch

- BeeGreen Operations Manager, Brian Fuentes, guides us through the process of turning everyday wood waste materials into new colored mulch (red, brown, or black). Clean wood waste (free of paint, stain, and any treated wood waste TWW) is converted to colored mulch through our Rotochopper FP66 high-speed grinder (with colorizing unit).
Located in Oakland, CA, Bee Green operates a large volume Transfer/Processing Operation which recovers large amounts of clean urban wood waste (from building remodels, demolition, etc). This wood waste is transported to our Chipping and Grinding operation which is featured in this video. In 2021 we purchased a Rotochopper FP66 with colorizing unit. Prior to 2021, we used to ship our ground materials (ground using a Beast 3680T manufactured by Bandit Industries) out to a mulch producer in central California. That meant we had to 1) pay for the material to be shipped on the freeway in a semi-truck out to the valley 2) pay the mulch manufacturer to take the materials 3) have that manufacturer make colored mulch with our materials in his machine 4) buy the colored mulch from the manufacturer and 5) pay to have the colored mulches shipped on the freeway in a semi-truck back to our facility for resale. Now, we make the finished product ON SITE! saving two semi-trucks worth of traffic for every 100 yards of mulch produced. This is now an efficient closed-loop recycling operation as you will see below...
The clean wood is sorted to separate the materials that are difficult to colorize with the non-toxic colorizers used in our process (see www.beegreen.green/site/asset.... There are some pallets that have a waxy sealer on them that do not allow the colorant to stick to the wood. Those are sorted into a separate pile and ground separate. That material is ground, and sold to a biomass plant where it is used as fuel to create electricity in California!
After the material is sorted, it goes through a "primary grind". That is, the full pieces of wood are sent through the FP66 grinder that is configured with 4" screens. During the primary grind, the clean wood waste is sized to a uniform 4" minus product. There are two magnets on the FP66 which are used to remove nails and other ferrous metal debris. A cross belt magnet, and a head-pully magnet. The magnets deposit the metal into a bin that is used to collect the metal debris for recycling at a local metal recycler (www.dcmetals.com).
After the primary grind, the grinder is set up for the colorizing regrind. A smaller set of screens is swapped out for the larger 4" screens used in the primary grind, and the colorant and water supply are hooked up to the Rotochopper FP66's colorizing unit which is controlled by the FP66 onboard computer system. The computer system monitors and controls how much water and colorant are added to the patented grinding chamber where all the mixing action takes place (not an area we can get a camera into, it would destroy it!!) However, due to the varied materials being processed, the operator has to continuously monitor the output materials and make any adjustments necessary to maintain a quality colored mulch product.
The colored mulches are sold from our Oakland location all throughout the Bay Area!
WARNING! do not eat mulch. Though the colorant used is considered non-toxic, the mulch is WOOD. Humans do not eat wood. Brian is only playing around and is not actually drinking the colorant NOR eating the finished colored mulch. This should go without saying, but you never know these days!

Excellent video, Bee Green team! Brian, you are a natural in front of the camera, good sir!
Thank you
Great video!!
Great video Thanks for sharing. Question: How to you control the overall quality and toxin levels from things like paint, if the mulch comes from so many different sources? How do you prevent nails and such from pallets and other foreign hamrful objects from getting mulched? Thank you!
Quality on the output is determined by quality in the input. You know the old saying, “garbage in = garbage out”. Our processing facility only accepts clean wood waste. Additionally we have staff that inspect incoming materials for contamination (painted, treated wood, etc).
By the time the mulch is finished going through our process it has passed by large magnets 4 times. This removes nearly all tramp metal (nails, screws, brackets, etc) in the wood waste.
Thanks for watching.
Very funny dude
Glad you enjoyed
what is that brown mulch dye made out of? is it toxic? how much does a pallet cost?
Red mulch is iron oxide dye. Black mulch is carbon (charcoal) dye. When you combine the two in different proportions you get different shades of brown. It is not toxic, it's just rust, and iron is a vital plant nutrient. People apply it to their lawns to make grass more dark green.
Ill bet most people think the trees come red, green, mocha etc....lol
This not not how mulch is made in Massachusetts maine and new Hampshire. We use bark from trees and only color black and red everything else is natural
Can you tell me what colourant i have to use metal oxide?
