The opponents of
cannabis stink compare the scent of buds at harvest to skunks. However, beyond
its fragrant nose, cannabis enterprise holds an aroma welcome even to many who
shun pot: the smell of money. While cash gushes from the evolving industry, the
cannabis operators must reckon with the reek, which makes neighbours, a lot of
them, smoking mad.
Often, people object
to the proposed commercial growth of marijuana adjacent to their home, with
their primary objection lying against the odor-smell created by the plants. The
smell is sewer-like or skunk-like, usually travelling long distances.
To mitigate the odor, the
air within the facility must be ventilated through particulate arrestance,
high-efficiency filters. The cannabis processing and cultivation rooms comprise
many layers of carbon filtration (including activated carbon pellets) and fan systems, also consisting of
scrubbers. The carbon filter pellets
are designed to control odors, VOCs (volatile organic compounds like
hydrocarbons and paint fumes), and other gaseous contaminants.
Fruity Aromas
The olfactory
challenges have a scientific basis in essential oils for industrial engineers.
The fatty acids naturally occur in cannabis and other plants, producing fruity
aromas like that of apple cider, banana, or berries.
Terpenes, which is a
fragrant essential-oil compound of carbon and hydrogen, account for piney,
citrusy, floral, and sweet scents in cannabis. Terpenes can have both beneficial
and olfactory effects – antiviral, anti-inflammatory, and antiseptic. Myrcene
noted for anti-inflammatory, analgesic (pain relief), and sedative effects,
occurs in a variety of cannabis strains as well as in basil, lemongrass, thyme,
mangoes, and hops. Linalool is a terpene found in lavender and cannabis and is
prized for its stress-reduction effects.
The Science Behind Skunk Odor
Some critics of
cannabis describe its smell as skunky during flowering. Cannabis comprises
alpha-linolenic acid, which, under the influence of UV rays of sunlight, may
break down into butyl and methyl thiols. Whether the smell is skunky or not, it
is a serious business challenge for which the engineers have always been
sniffing out solutions.
According to experts, the
smell is much more prevalent in the trimming process when you’re breaking
plants open. This is where many odors are emitted. However, the potency of
smell depends upon the plant size and strain. The sativa or indica plants grow
in different styles, with cultivators topping the plants early, so they have a
very quick growing cycle.
Plume Discharge At 34mph
The management of
cannabis reek isn’t just about filtration through carbon pellets; it’s how you get rid of it. Some industrialists
take an industrial-ventilation approach by trying to get a high plume coming
off the exhaust fan. By discharging the air high into the atmosphere, we ensure
that the wind current takes it away without anybody on the ground ever
noticing.
While filtration takes
out the majority of the particles that smell, a highly efficient particulate
air filter with activated carbon pellets
accomplishes 99.6% removal of particulates. While resulting air could still
smell faintly of cannabis at the emission nozzle, this isn’t true at the ground
level. The airflow is killed by capturing 100% of particulates, creating
unhealthy indoor air. To mitigate this, typical HVAC systems must be bolstered,
and recirculation systems must be employed. Beyond diffusers and terminals, oscillating
fans ensure that the air mixes properly.
Dehumidifiers To Fight Mold
Mold is a huge deal
and must be taken care of. Every plant transpires – drawing water from roots
and evaporating it from pores on leaves. The system must respond variably to
different zones because small plants transpire less than big ones.
Cannabis processors
use ethanol for cannabinoid extraction. It’s heavier than air. The
industrialists use slotted hoods with low intakes to draw in or entrain
ethanol. Then they take it out, which gives off the odor, and they filter and
treat it.
Adapting Existing Buildings
Few buildings planned
for cannabis processing or cultivation don’t have roofs built to handle loads
like bigger air-filtration units, entailing modifications. Currently, the roof
structure for most buildings won’t allow for a 500-pound exhaust fan to go up.
Therefore, they can locate it inside instead of mounting the unit up on the
roof. Just try running the duct up through the roof, and you’ll be good!
