  • Reducing world's carbon footprint by producing
    valuable sustainable products from rubber waste
    and creating “Green Jobs”, is the vision of
    El Toro Verde.
  • Our mission is to remove toxic waste like rubber and ELTs from our environment and increase
    the value of such waste by using it as non-natural renewable source for our, zero-emission,
    patented technology producing green limonene, green commercial active carbon and green fuel oil
    while having a beneficial impact on both the environment and the economy.

Welcome to El Toro Verde, a Dutch initiative on Spanish soil.

We are committed to address global challenges in regards to our environment with our patented Chemical Recycling through Pyrolysis of Rubber waste (CRPR) technology, which enables us to turn rubber waste, such as End-of-Life Tyres (ELTs), into Limonene of high purity and Active Carbon.

In loving memory of our friend, José Leandro “Lalo” Martinez Camus.
Unfortunately, there was not enough time for you, but we will do everything to realize your dream! Rest in peace.

We will turn black into green, step by step and tire by tire!

Feel free to contact us for more information about El Toro Verde, our technology and/or our project.


Sustainable recycling of rubber waste has become a serious global challenge. End-of-Life Tires (ELTs) and industrial rubber waste is a serious environmental problem. Worldwide about 17 million tons and in the EU alone around 3.4 million tons of tires become waste each year. In Spain alone the yearly production of industrial rubber waste and End-of-Life Tires is about 330.000 tons. Current recycling methods of this waste does not meet the European legislation (REACH) and in less than five years these methods cannot be used anymore. Therefore the amount rubber waste is increasing while already 10 billion tires are lying in garbage dumps all over the globe. These are a constant source of pollution and the fire risks are very high.

Solvent is one of the most commonly used product families in the industry. The greatest amount of solvent is used for coatings and paints but also as ingredients of medicines and cosmetics, insecticides, adhesives and cleaning products. Due the emission of VOCs into the atmosphere and new laws and restrictions, the replacement of currently used solvents by greener, sustainable alternatives must become a fact in the coming years.

There is a growing demand for foods that are not treated with the traditional insecticides but with products that are not toxic to humans and pets nor harmful to gardening nor plants indoor nor for the environment and can be used in homes, offices and schools.

Worldwide there are continuous demands for cleaner production in enterprises in order to reduce the emissions of mercury, acid gases, metal and other hazardous air pollutants to meet certain standards for emissions of Western governments. Changing the production processes is very costly so to meet the requirements these industries will predominantly turn to filter and cleaning systems which use active carbon.

Our Solutions

With our patented Chemical Recycling through Pyrolysis of Rubber waste and End-of-Life Tires (CRPR) technology we are able to recycle rubber waste and End-of-Life Tires (ELTs) in a sustainable and renewable way into Limonene of high purity and Active Carbon, addressing the challenges mentioned before by reducing rubber waste and creating sustainable products that can be used as solvent, insecticide and for purification. 

From the environmental point of view, it is important to mention that products or recycled materials and/or obtained results from our process fully comply with European legislation (regulations REACH – CLP), resulting in healthy products that are safe for the environment, meeting the objectives of the circular economy. The implementation of our technology allows certifying according to ISO 9000 and 14000, which determines our industrial facility as a “zero emission plant” in environmental perspective.

According to the EU Renewable Energy Directive (RED), waste has a zero carbon footprint. As a result of this rubber waste and ELTs do have a zero CO2 rating. Since rubber waste and End-of-Life Tires will be the feedstock for our CRPR technology and the fact that its installation is a zero emission plant, all products produced in this facility are classified as sustainable, renewable and green products.


During our CRPR process different fractions are obtained from the rubber waste and separated. These fractions needs further treatment such as purification, resulting in a facility that will eliminate toxic waste, with the consequential environmental benefits, resulting in a number of various high value sustainable products.

Green Limonene

The liquid fraction (rubber-derived oil) from our CRPR technology will be processed for separation and purification of our important product Limonene. Our Green Limonene will have a purity up to 98%. The quantity of our Green Limonene is guaranteed at 20% of the original weight of the waste.

Green Active Carbon

The Pyrolysis reactor is provided with overflows for the extraction of the second product of the process, Carbon Black. Activation treatment of the carbon black develops the specific surface >= 1000 m2 / gr. that classifies our product as Green Active Carbon of commercial quality.

Green Fuel Oil

The other fraction in the pyrolysis oil that is separated with our technology can be characterized as a light and medium Fuel Oil. We will produce about 40% by weight. Treatment by additivity and stabilization allow to obtain approved and homologated fuels for vessels. 


The aim of our project is to realize our first plant in Spain and implementing our patented Chemical Recycling through Pyrolysis of Rubber waste and End-of-Life Tires (CRPR) technology and its auxiliary systems.

The plant will have a capacity of approximately 1.500 kg of rubber waste per hour resulting in 11.169 tons of rubber waste processed yearly and producing 2,6 Million Litre Limonene, 1.346 tons Active Carbon and as a rest product approximately 5 Million Litre Fuel Oil for vessels.

We can roughly divide the project in two phases:

  1. Preparation. Will last up to 15 months maximum and will start as soon as possible.
  2. Construction. Will last up to 15 months maximum. This phase will start in the 4th quarter of the 1st year of the project. Preparation and construction phase will have an overlap of approximately 6 months.

Subsequent to phase 2, in the third year of the project, the production will start.
