Color Remediation or CRC (color remediation column)  broadly refers to both a specific component and a process in cannabis extraction. A CRC column or chamber is filled with various adsorbent materials. These materials are specially chosen for their ability to filter out unwanted compounds from the cannabis extract. The primary function of the CRC is to purify and refine the oil produced during the extraction process.

Typically made of stainless steel, the column is designed to withstand the pressures of BHO extraction and to facilitate the easy flow of extracts through the adsorbents. The core of CRC technology lies in adsorbent materials—including activated clays, silica gel, and other specialized filtration media—each selected for their specific impurity-adsorbing properties.

Importance of Color Remediation in Cannabis Extracts

The integration of CRC technology into BHO extraction has brought about significant advancements in the quality and purity of cannabis concentrates. As a result, producers are now equipped to meet and exceed the evolving expectations of discerning consumers.

What are Cannabis Extracts?

Cannabis extracts are concentrated forms of cannabis obtained through various extraction processes. These extracts contain high levels of cannabinoids, such as THC and CBD, and are used in multiple products, including oils, edibles, and topicals.

Types of Cannabis Extracts

• Shatter: Known for its glass-like clarity and brittle texture, shatter is crafted by meticulously purging solvents while preserving its translucent appearance. 
• Wax and Budder: These softer, more malleable concentrates are created by agitating the extract during purging, introducing air that changes the texture. 
• Crumble: A drier form of concentrate that's achieved by spreading thinly on parchment paper or silicone mats and purging at relatively lower temperatures for extended periods.
• Live Resin: Made using fresh frozen cannabis to preserve more terpenes, live resin is extracted at low temperatures and undergoes minimal post-processing to maintain its robust flavor and aroma.
• Distillate: This process involves further refinement of the BHO extract, including distillation, to isolate specific cannabinoids like THC or CBD, resulting in a highly potent and pure product.
• HTE (High Terpene Extract) begins by separating terpene-rich fractions during extraction and combining them with high-cannabinoid parts of the extract. This process maintains a balance of flavor and potency.
• Isolates (THC/CBD): Produced through additional refinement steps such as winterization, decarboxylation, and crystallization to isolate and purify THC or CBD into a nearly 100% pure form.

BHO and ethanol extraction methods can produce a wide range of concentrates with exceptional purity and enhanced flavor profiles. However, some products, like solventless hash oil (SHO), are impossible through these processes. SHO is created using mechanical or physical methods without solvents.

While SHO is prized for its natural extraction process, BHO extraction with CRC stands out for commercial viability. CRC enhances scalability and ensures consistent product purity, which are advantages crucial for large-scale operations that solventless methods like SHO may not match.
