Partnership Between Public Universities and the Federal Police Studies the Use of Cannabis Sativa L. as a Raw Material for Biofuel Production.
Researchers from the Federal University of Pará (UFPA) and the Federal University of Santa Catarina (UFSC), in partnership with the Federal Police, are developing a new alternative for the repurposing of seized drugs in Brazil. The study, named Project Cannabiocombustible, investigates the energy potential of marijuana as a raw material for biofuel production.
The initiative aims to combine sustainability and innovation in addressing logistical challenges of public safety. The project focuses on transforming the biomass of Cannabis sativa L., a plant commonly seized in police operations, into energy products such as biodiesel, biogas, and biochar.
Use of Pyrolysis as a Technique for Converting Marijuana into Biofuels
To convert marijuana into biofuel, researchers use a technique called pyrolysis, which involves the thermal decomposition of organic material in an environment with little to no oxygen. During this process, the plant transforms into three main byproducts: biodiesel, biogas, and charcoal (also known as biochar), as well as pyrolytic vinegar.

Italy bets on Brazil’s potential to lead the advance of biofuels and expand strategic cooperation in renewable energy, sustainability, and global emissions reduction.
Biodiesel can be used as liquid fuel after refining; biogas can power engines or generate electricity, and biochar has agricultural applications, contributing to soil improvement. The research is currently in the efficiency testing phase, aiming to optimize variables such as temperature and reaction time to enhance the energy yield of the process.
Marijuana as Biofuels: An Alternative to the Traditional Disposal of Seized Drugs
Currently, most of the marijuana seized in Brazil is destroyed through incineration. This procedure requires specific structures, the relocation of federal police teams, and constant monitoring to ensure safety during the transport and disposal of the substance.
With the advancement of Project Cannabiocombustible, the goal is to offer a more sustainable and economical alternative for dealing with the seized material. The idea is that, instead of being completely incinerated, the drug could be directed to energy transformation units, reducing operational costs and minimizing logistical risks.
Partnership Between Science and Public Safety
The proposal arose from a technical cooperation between the Federal Police, UFPA, and UFSC. The study is conducted with judicial authorization and in controlled environments, following legal requirements. The researchers hope that, with the necessary legal and technical adjustments, the process can eventually be replicated on a pilot scale with the support of environmental agencies and public institutions.
The project also involves training agents and professionals to handle the plant raw material, ensuring that the entire process occurs safely and with traceability.
Potential Environmental and Energy Benefits
In addition to solving a recurring problem in the public safety system, transforming marijuana into biofuel represents an innovation in the field of sustainable energy. The use of unconventional biomass as an energy source aligns with the goals for transitioning to a cleaner and more decentralized matrix.
According to the coordinators of Project Cannabiocombustible, the biomass of the plant has physical and chemical characteristics compatible with other plant sources already used in the production of biofuels, such as sugarcane bagasse and wood. The research aims to understand the thermal behavior of Cannabis and test its viability in different energy applications.
