WHY RECYCLED COFFEE?
WHAT ARE USED/SPENT COFFEE GROUNDS (SCG),
A.K.A. COFFEE 'WASTE' ?
In 2018, over 9 billion kilos of coffee were consumed worldwide. When you brew a cup of coffee, less than 1% of coffee's health-enhancing compounds are utilised.
99% has been mistakenly treated as waste for centuries.
In short, SCGs are the coffee grounds remaining after your brew. SCG is a by-product with fine particle size and high organic load. Its chemical composition is based on cellulose, hemicelluloses, proteins, lipids, polyphenols, minerals and different products formed by the Maillard reaction during the roasting process, such as melanoidins.
These compounds have shown several biological activities, including anti-proliferative, antioxidants, and antimicrobial effects (Mariotti-Celis et al. 2017).
HOW DOES COFFEE 'WASTE' CONTRIBUTE TO CLIMATE CHANGE?
Every day, over 2.25 billion cups of coffee are consumed worldwide, and the SCG often ends up as waste in plastic bags, mixed with other trash in garbage dumps.
The 9 billion kilos of coffee consumed yearly worldwide is treated as waste, or is not properly disposed, being left decomposing in a landfill and generating tons of methane a day, a greenhouse gas 86x harmful for the environment than CO2.
For every tonne of coffee “waste” decomposed in a landfill, 340m3 of methane are released in the environment.
The yearly environmental impact of coffee waste decomposition is equivalent to
9 million car emissions.
CURRENT SOLUTIONS FOR RECYCLING COFFEE ARE NOT ENOUGH...
Some use used coffee grounds as soil fertiliser. However, this practice is far from environmentally friendly. The high presence of organic material makes the decomposition process of the SCG highly pollutant since it requires important volumes of oxygen and releases methane into the atmosphere (Silva, Nebra, Machado-Silva, & Sanchez, 1998; Ballesteros et al., 2014).
Even more, caffeine and polyphenols give the SCG a high toxicity rate, especially for the soil ecosystem. When discharged into landfills, the SCG consequently represents a pollution hazard (Cruz et al., 2012; Mussatto, Machado, et al., 2011; Ricardo, Pascoa, & Magalhaes, 2013).
WHY KAFFE BUENO?
Kaffe Bueno’s mission is to better utilise coffee "waste"; that is to fully exploit its health properties in an environmentally friendly way. Spent Coffee Grounds are a valuable resource that has been wrongly treated as waste for centuries, until now.
Its potential is huge, and several studies have highlighted the opportunities associated with the use of SCG in food and cosmetics products, thanks to its high content of antioxidants and fatty acids that benefit health and skin(Bessada et al., 2018; Kourmentza et al., 2017; Scully et al, 2016; Martinez-Saez et al., 2016).
For every tonne of coffee grounds recycled, we avert the emissions of 340m3 of methane into the atmosphere. Within the next 5 years, we are planning to recycle 1600 tonnes of coffee yearly, which is equivalent to 3 million average car emissions per year.
Not only do we extend the life of coffee, but we allow companies and people to benefit from its virtues for longer, all through a way that is Bueno for You, Good for All.
