From Coffee Cup to Cannabis Cup

November 4, 2021

The importance of a simple cup of coffee cannot be understated as a farmer. It provides many farmers the morning jolt after getting some well-deserved “Z’s” after a typical day of work on the farm. The warming liquid was essential for my 4:30 am mornings and an essential pick me up at midday when it was time to transition from the morning tasks on the farm to the business tasks required behind the desk. I understand the importance of it for myself when it came to simple energy but discovered its true value when I started utilizing it on a commercial scale in my compost pile and for my plants indoors and outdoors.

That works for a small-scale farming system sure, but what about indoor grows or commercial cannabis farms? Can it be a commercially viable soil source? Can it grow outstanding, nutrient dense plants? Can a Texas company find an agricultural solution for industrial coffee waste?

1 It has been found that over 93% of coffee waste from cafes send their spent coffee grounds to the landfill. That’s over 558 million pounds of nitrogen wasted annually!

Coffee & Circular Economics in Agriculture

Cup o’ Joe, Morning Brew, Wake-Up Juice, Java, Café, Bean Juice, the list goes on for the common slang words used as nicknames for coffee, but one thing is for certain, people love drinking it and it is a staple for many households and businesses alike. 7 out of 10 Americans drink coffee every day. The average coffee café utilizes over 12 pounds of coffee daily. That equates to over 4,300 pounds of spent coffee grounds produced annually. [i] For every 2.20 pounds of new ground coffee used it produces 4.18 pounds of spent coffee grounds that has to be handled. How do most consumers, coffee shops, and industrial beverage producers handle the tremendous amount of waste produced by the delicious beverage that over 62% of Americans enjoy on a daily basis? [ii] Unfortunately, it has been found that 93% of that waste goes directly to the landfill. What does that mean?

This means according to some estimates, around eighteen million tons of used coffee grounds go to landfill each year.

However, when coffee grounds break down in landfill sites they emit methane, a greenhouse gas up to 28 times more damaging than carbon dioxide. This poses serious problems to the planet due to global warming. [iii]Out of the 20 billion pounds of coffee produced around the world will be contributing to methane production in landfill rather than being utilized in a circular economics system. [iv] It also means that 558 million pounds of nitrogen, 1.1 million pounds of phosphorous, and over 111 million pounds of potassium that can be potentially utilized for agricultural purposes but rather sits dormant in landfills creating nutrient runoff and pollution because it us not placed into a circular economic system.[v]

What is circular economics and how can it be utilized in agriculture? The basic principle of circular economics is that waste becomes a resource but rather a byproduct for another use. Ask any experienced organic farmer about their farm system and they will tell you that they know exactly what comes into their farm and what purpose it serves, from the seeds, the soil components, and

equipment and they will tell you exactly what comes out and at what point. The agriculture sector is very unique and utilizes mostly natural resources for ideal product production. Unfortunately, the standardization of agricultural production has created a reliance on technical nutrients and away from biological or natural nutrient sources. This adoption by traditional agriculture has created a more linear approach to production. ­Most companies harvest and extract resources or materials and use it to manufacture a product that is sold to a consumer that later discards the product once it is used or no longer serves a purpose. This economic flow relies heavily on high-intensity exploration, overseas production, and consumptions of resources at a high-intensity damage to the environment.[vi]

Think of the idea that allowed early European settlers to adapt to the unfamiliar terrain of early American soil. The use of using rotting fish heads in the soil prior to planting corn. [vii] They learned to eat majority of the fish but put the “waste” to work to grow crops that sustained their long-term settlement goals and created one of the first circular economies in the Americas. But what exactly does it mean for today’s modern farms, landscapers, or gardeners? What does coffee have to do with the push to create a more circular economic system literally from the roots up in a farm system? The answer is inside the very cup that farmers enjoy every morning.

Industrial Coffee Waste Turned into Soil

Much like the story of the fish heads being utilized used in early settlers’ life much of the story is surrounded by myth but one thing remains true, the nutrient

content and biological reaction the soil has to the decaying fish increases the plants nutrient availability and promotes healthy soil growth that in turn creates healthy soil growth. [viii]These early principles in agriculture have created industries around utilizing waste from fisheries, canneries, and processors around the world and turning into a productive soil nutrient essential for growing healthy soil systems that produce nutrient dense crops.

The growing popularity of cold-brewed coffee and the increased demand for coffee has created a unique opportunity for Chad McNair, CEO of Aspen Beverage Group in San Antonio and David Mayer, owner of Mayer Materials in Fort Worth to the creation of a company, Texas Java Partners LLC, that research, develop and produces innovative coffee-based fertilizers, composts, and organic matter root-zone amendment products.

Coffee waste is produced every single day at staggering rates throughout the world and there is not enough being done to remediate that waste and divert it from landfills. Texas Java Partners LLC teamed up with Texas A&M AgriLife Research’s Doctor Ben Wherley to conduct an experiment with the spent coffee ground to divert waste from industrial coffee beverage manufacturing from landfills and rather use it in commercial agriculture. It was found that coffee grounds can cover a lot of ground. Wherley said Aspen Beverage Group supplied much of the spent coffee grounds for his team’s research projects, which looked at the cast-off products as a surface application, perhaps as a fertilizer or compost, and as a soil root-zone amendment in sand-based systems.

Spent coffee grounds have about a 2.5-3 percent nitrogen content, and a carbon-to-nitrogen ratio of about 20 to 1, which seemingly could make them desirable for fertilizer application, Wherley said. The two-year topdressing fertilizer study tested seven different organic and synthetic fertilizers against coffee grounds — fresh and composted — as well as a control. The study also tested two application rates for each treatment.

“Our observation from this study determined that direct application of spent coffee grounds by themselves provided minimal benefit,” Flores said. “However, when the spent coffee grounds were added with another source of fertility, the nutrients appear to be retained over an extended period compared to organic and especially synthetic fertilizers.”[ix]

This discovery can immediately create a more sustainable and effective nutrient availability in an emerging cannabis soil marketplace. The realization of agricultural products being developed from industrial coffee waste was born and has positive effects for the cannabis industries ecological and sustainable footprint alike.

Cannabis is mainstream, the industry is booming but its earthy and all-natural branding doesn’t tell the whole story. You thought your cannabis came from environmentally conscious hippies? Think again. The way cannabis is currently being grown in America, it turns out, is anything but sustainable and organic. To meet the $30B demand cannabis is being grown relying on massive amounts of energy, heavy doses of agro-pesticides and fertilizers which can cause dire effects on the natural world around the grow site. From wastewater runoff to the emissions load required to import raw materials from out of country there must be something done to reduce to negative effects of growing cannabis.

More growers, companies, and lawmakers alike are noticing that growing green isn’t as green as it is made out to be. The growers that adapt to certifications, utilizing sustainable growing solutions, and embrace nature will prevail over linear cultivators who utilize single use nutrients and growing methods.
