Slideshow to show the process and benefits of recycling food waste and composting it to organic soil. Utilizing the resources to reproduce food for our world is a benefit to everyone involved.

2. Bay Mulch – Our Story
• Bay Mulch Inc, was incorporated as a Florida Corporation in 1996
• Started out as a land clearing and grinding company
• In 2002, opened a yard-waste recycling / mulch production facility in
Pasco County, FL
• In March 2013, opened a compost facility on 42 acres in Plant City, FL.
Processing yard waste and pre-consumer food waste.

4. Wood Processing
• Land clearing debris and materials from landscape maintenance crews,
are carefully separated into yard waste, large limbs, and soil
• Yard waste is ground and utilized for composting
• Large branches and logs are processed into mulches and potting soil
components
• Soil is sold as clean fill; or compost is added to produce top-soil

5. Food Waste Collection Services
• Bay Mulch owns a fleet of specialized collection vehicles for the
efficient handling of food waste
• We provide roll carts to our customers

6. Collection
Filled roll carts are placed outside by our customers on
collection days

7. Some of our customers utilize
plastic cart liners
Clamps are utilized to secure the
bags to the carts

8. Rear-mounted cart lift
System
capable of
lifting three
carts at once

11. Soiled plastic roll-cart liners are
removed from the emptied carts
and are placed in a roll cart that
stays with the vehicle

12. Composting
• Bay Mulch utilizes Harvest Quest’s inoculant and Modified Static
Aerobic Pile (MSAP) composting methodology
• This method has proven to be very consistent and allows us to
operate our facility without odors and nuisance vectors such as
flies and scavenging birds
• The finished compost is of the highest quality and was recently
approved as an input by the USDA National Organic Program

13. Process Steps - Receiving
A three-sided receiving bunker
is constructed from ground yard
waste
The bunker has a base layer to
provide absorption of any free
liquids
The food waste receiving area is
located on a concrete pad,
which provides an all-weather
operating surface and easy to
clean work space

15. Driving heavy equipment over the food waste
eliminates rolling fruits and vegetables and
facilitates more rapid decomposition

16. Addition of Moisture

17. Mixing

18. Windrow
Construction
• Windrows are constructed to a height of approx. 7 feet
• Inoculant is applied to the ends of the windrow on the surface
• Finally a capping layer is placed over the piles

19. The Capping Layer Provides:
• vector attraction reduction by creating
a physical barrier between the contents
of the pile and the outside air.
• an instant biofilter providing excellent
odor mitigation.
• it insulates the pile allowing for high
temperatures to be achieved all the
way to the edges of the mixed
contents.
• protects the contents of the pile from
external influences, such as heavy
rainfall or extreme cold

20. • The bacteria within the inoculant spread rapidly outward from the
points of application initially populating the outer edges of the
windrow just beneath the capping layer.
• This prolific microbial activity
generates initial temperatures
on the surface of the pile
• The microbes then work their
way towards the center of the
windrow breaking the contents
down from the outside in
• This action increases the
windrows natural chimney-
effect, allowing sufficient air-
flow into the pile

21. • Within several days the whole pile will far exceed 131⁰F (55⁰C)
and elevated temperatures will be maintained for several weeks
• The windrow remains
undisturbed for an initial
28 to 35 day period
• After the initial static
phase the windrow is
turned for the first time
• At this point in time the materials will be sufficiently composted
as not to produce any offensive odors
• Turning the windrow at this point reduces compaction and
redistributes moisture

22. • Following a further 14
days of composting the
windrow is turned a
second time. Again,
moisture is redistributed
and at this stage the
windrow will be entering
the final phase of
composting.
• The properly controlled
marriage between
bacteria and compostable
materials produces
quality finished compost
in 45 to 60 days.

26. Potting Soils
• High-Quality, Low Cost
• pH Balanced
• Peat Free
• Bark Free

28. So Why Incorporate Food Waste?
• Preserves landfill space;
• Reduces greenhouse gas emissions;
• Diverted tons contribute to mandated recycling targets;
• Composting recycles organic matter and nutrients back to
the soil;
• Redirects funds (tipping fees) to sustainable waste
management practices;
• Speeds up the composting process by providing a more
suitable Carbon to Nitrogen (C:N) ratio;
• Produces a higher value, more nutrient-rich compost
product.
