Like other businesses, marijuana companies in the US are responsible for adequately disposing of their waste. However, there are no federal guidelines regarding how this can be done. This means they must figure out how to do so in a way that complies with local and state laws. 

Due to the growing popularity of marijuana, the amount of waste generated by the industry has become an increasing concern. Each year, millions of pounds of marijuana are grown. As the industry continues to grow, more waste is generated by companies.

Cannabis Waste Defined

The waste that marijuana companies are responsible for includes various materials from their production, processing, and packaging. Some of these include unused buds, stems, and leaves. In order to avoid violating the law or damaging the environment, marijuana companies must thoroughly remove these materials.

In this article is a list of methods used by marijuana companies can properly dispose of their waste.

Licensed Landfill

Permitted landfills allow companies to transport their waste to an approved site, where it can be buried. Although this method works, it can be very time-consuming and expensive.


Another way that marijuana companies can use to dispose of their waste correctly is by composting. This process involves separating organic matter into nutrients. However, certain products, such as concentrates and edible products, might not be suitable for composting because they have other components.

In-Vessel Digestion

In-vessel digestion is a newer process that marijuana companies commonly use to dispose of their waste. This method involves placing the waste inside an airtight container, allowing it to decompose. Compared to traditional methods, in-vessel digestion is more effective and efficient.


The process of incineration involves burning the marijuana waste at a high temperature. This process then turns the material into ash, which can be safely deposited in landfills. Some companies use special filters to prevent harmful particles from escaping.


Not disposing of waste properly can threaten the environment. Since marijuana is a harmful substance, companies must hire a recycling company to handle their waste adequately.

The waste from marijuana production can also threaten the environment. It can enter the water supply and soil, harming aquatic life and plants. However, some of the material can be recycled to create a more eco-friendly product.
