Comparing GHG Emissions: Vegetable Oil from Crops vs. Recovered Vegetable Oil (RVO)

Comparing GHG Emissions: Vegetable Oil from Crops vs. Recovered Vegetable Oil (RVO)


In an era where sustainability and environmental concerns are at the forefront, understanding the greenhouse gas (GHG) emissions associated with different processes is essential. One such comparison revolves around vegetable oil production – traditional vegetable oil derived from crops versus Recovered Vegetable Oil (RVO) made entirely from waste and residues. This article delves into the GHG impact of these two methods, shedding light on their contributions to a greener future.

Vegetable Oil from Crops: A Conventional Approach

Traditional vegetable oil production involves cultivating oil-rich crops like soybeans, canola, sunflower, and palm. The process encompasses land cultivation, fertilization, irrigation, harvesting, transportation, and extraction. Each stage of this process contributes to GHG emissions, primarily in the form of carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). The carbon footprint is substantial due to deforestation, land-use change, and the application of synthetic fertilizers.

The GHG Impact of Recovered Vegetable Oil (RVO)

Recovered Vegetable Oil (RVO), on the other hand, offers a more environmentally friendly alternative. RVO is sourced entirely from waste products and residues generated in the crushing plants, vegetable oil refineries and/ or biodiesel plants. The production of RVO reduces the need for cultivating new crops and mitigates the environmental impact of waste disposal. The process involves collection, cleaning, and filtering the waste oils, sediments and/ or any other vegetable waste and residues generated by the producing plants.

Comparative Analysis: GHG Emissions

  1. Cultivation and Land Use: Traditional vegetable oil production requires significant land use, leading to deforestation and habitat destruction. RVO, however, eliminates this need for agricultural land and, consequently, lowers associated emissions.
  2. Energy Consumption: RVO’s production process typically demands less to almost none energy than traditional oil production, as the feedstock is already available and doesn’t require the energy-intensive processes of planting, growing, and harvesting.
  3. Transportation: While both methods involve transportation, RVO’s feedstock is often locally sourced waste, reducing transportation distances and associated emissions.
  4. Processing and Refining: RVO requires less refining, as it’s often sourced from already processed waste and residues oils. Traditional oil refining emits substantial GHGs due to energy-intensive processes.
  5. Waste Reduction: RVO not only produces oil but also repurposes waste that might otherwise end up in landfills or incinerators. This waste reduction indirectly contributes to lowering emissions associated with waste management. All remaining materials after processing are 100% recycled so RVO is production is fully green.


When evaluating the GHG emissions of vegetable oil production, it becomes evident that Recovered Vegetable Oil (RVO) presents a more sustainable alternative compared to the conventional crop-based approach. By eliminating the need for new agricultural land, reducing energy consumption, utilizing waste products, and curbing the environmental impact of waste disposal, RVO stands as a viable solution to address the sustainability challenges posed by traditional vegetable oil production.

As we move towards a more sustainable future, understanding the impacts of various processes is crucial. Adopting innovative approaches like RVO not only helps reduce GHG emissions but also promotes a circular economy and resource efficiency, setting a positive example for the food and agriculture industry as a whole.
