What is Hempcrete?
Hempcrete is a bio-composite mixture that is most commonly used in the construction industry as a sustainable alternative to concrete. Each batch of Hempcrete at Modpot is individually mixed with locally sourced materials that are favorable for plant growth, including hemp shiv (the wood-like core inside the stem) and hypertufa (a type of limestone that augments the strength and porosity of hemp shiv).
Historically, hemp has been utilized by civilizations dating back to the Neolithic Era (10,000BC). In fact, Cannabis Sativa, also known as the common hemp plant, is on record as one of the earliest domestically grown plants. It was, and still is, used to make a variety of everyday items such as textiles, rope, paper, and oil. Although there are claims that Hempcrete in its current form was introduced in the 1980s, further discoveries suggest it actually dates back to the 1600s. Seldom used outside of construction today, Hempcrete has just begun to gain popularity in the United States.
Concrete is a leading contributor of greenhouse gases globally, and is responsible for around 4-8% of the world’s CO2. Among materials, the CO2 production of concrete is subsequent only to oil, coal, and gas*! These emissions are a result of its manufacture-intensive nature and high energy use.
In addition, hemp sequesters carbon throughout its lifetime, making it ultimately carbon-neutral!
Although buildings are individually using about 1.5% less energy each year, an increase in industrialization means that related carbon emissions are expected to double in the next 30 years.
A report published by the World Resources Institute states that according to the Paris Agreement, all buildings must achieve carbon neutrality by 2050, yet so far less than 1% have done so.
