We have developed a responsible policy for caring for the environment that is based on the UNE-EN ISO 14001:2004 standard and seeks to minimize and reduce the effect of our activity on the environment, in particular by controlling environmental pollution and ensuring the efficient use of natural resources.

Through its organization, Orión is responding to the need to implement new technologies that comply with new global regulations to protect the environment, as well as to take part in other technical initiatives, such as plans and plants for treating municipal and/or hazardous waste,treating waterrenewable energiesSmart Citiestelecommunications, etc., which we do by entering into strategic partnerships with specialized or local companies.

Our solutions

MSW (Municipal Solid Waste)

Our plants are designed to receive, separate and treat the various types of municipal solid waste and to recover as much of it as possible.  

The input is the material that results from the collection of municipal solid waste. This material consists primarily of: organic material, paper and cardboard, plastics, glass, ferrous and non-ferrous metals, wood, cellulose compounds and others.  

We can divide these into two main groups: waste that can be recovered through energy and that which cannot.  

Waste that CANNOT PRODUCE ENERGY is: glass, ferrous and non-ferrous metals and others. This waste can be recovered in other ways. For example, ferrous and non-ferrous metals are sent for smelting, while glass can be used as an additive in asphalt paint.  

Waste that is RECOVERABLE is: Organic material, paper and cardboard, plastics, wood, cellulose compounds.  

As a general concept, the procedure is intended to reuse the raw material by breaking down the waste through hydrolysis, pyrolysis and thermolysis into materials with a low molecular weight. The process does not involve pressure.   

To reuse MSW, the recoverable materials are dried as much as possible in order to chemically or physically break the individual bonds between the links in the chains, and thus yield the original product once more, which in this case is hydrocarbons.  

The operating principle of the facility is based on the catalytic recovery of fuel (procedure without pressure). The goal is to introduce the input material into the reactor with as little air present as possible: Dry MSW, which is heated/evaporated and then allowed to condense again.  This guarantees the maximum recovery of fuel while at the same time minimizing undesired waste products like tar, coke and bitumen.

Processing of plastics

The plastics that are typically used in industry, and even in everyday life, are products whose ability to self-destroy is limited; as a result, plastic waste remains intact for many years, leading to terrible pollution problems. Since they come from petroleum products, plastic materials can become high-quality fuels if properly recovered. Plastics are an important material resource that we cannot squander or allow to go to waste. 

We are dissociating ourselves completely from incineration plants and opting for a technology that is both ideal and responsible. It’s been shown that burning plastics can cause serious harm to people and the environment. This is because certain plastics release toxic fumes when burned, such as polyvinyl chloride (PVC), which releases chlorine when burned. This can lead to the creation of highly corrosive hydrochloric acid and dioxins (which are extremely toxic and carcinogenic substances).

Our treatment plants take in all types of plastics and turn them once more into the original raw material: hydrocarbons. 

The operating principle of the facility is based on the catalytic recovery of fuel (procedure without pressure). The goal is to introduce the input material into the reactor with as little air present as possible:  dry, which then heats/evaporates before condensing again.

 One kilogram of polyethylene yields the same energy as a kilogram of fuel oil. 

The oil crisis in the not-too-distant future, due to the depletion of a non-renewable resource, justifies the research that Orión has been conducting for years to look for alternative energy sources. 

Hospital waste

Through its medical division, Orión provides a service to collect, use, process and recover infectious, hospital and drug waste. It does so using stringent environmental safety and quality parameters, and the latest technology in autoclave processes.


We not only eliminate the biological risks associated with the germs present in the waste, but the process does not product toxic emissions or effluents. There is also no additional risk posed to the workers involved in this process and no radioactive waste is generated. The process allows materials such as glass to be reused or recycled once they have been sterilized.

Disused tires

One of the most serious environmental problems in recent years has been the massive manufacture of tires, and the problems in disposing of them. Making a single tire requires large amounts of energy (half a barrel of crude for a truck tire). If the tire is not recycled properly, it also leads to environmental pollution, generally due to uncontrolled dumping. 

Until very recently, most disused tires ended up at controlled or uncontrolled landfills, where they not only pose a serious ecological problem, they also waste a valuable resource. The cement industry and others incinerated tires, but were able to recover very little of the heating value in the tires, thus wasting much of the maximum potential offered by this type of waste.

Our processing plants are able to process these disused tires to turn them into the original raw material: hydrocarbons. 

The operating principle of the facility is based on the catalytic recovery of fuel (procedure without pressure). The goal is to introduce the input material into the reactor with as little air present as possible:  dry, which then heats/evaporates before condensing again.

Treatment of sludge

Our sludge treatment plants offer a solution to the problems generated by sludge and to the increasing concerns of both society and public officials in terms of the proper handling of this material.

We use a modular rapid gasification system that treats the sludge thermally, drying it to reduce the final volume and then recovering it through gasification and eliminating up to 98% of the remaining waste.

The gasification system offers very important technical advantages over any other system available today since it can treat not only sludge, but also household waste, toxic waste, medical waste, etc.

The gasification reactor turns 98% of the sludge into gas, which is used to generate electrical and/or thermal energy. The remaining 2% is a product that can be used by industries that manufacture construction materials if the sludge is toxic, and if it is not, as an inorganic fertilizer for fields, gardening, etc. The end result of the process is significant energy recovery and the complete elimination of the waste.

Gasification, which is the process we use in our treatment, is accepted as a clean process that pollutes less than combustion, particularly with respect to the generation of dioxins and furans. It produces 50% lower atmospheric emissions than those permitted for the most modern incinerators. Incineration has a large impact on the production of acid rain, unpleasant odors, highly polluted air, on the hole in the ozone layer, on the installation of tall stacks, on high operating noises and on thick, black smoke. That is why it is important to differentiate between Orión’s system and other systems currently in use. We  DO NOT INCINERATE and our emissions are well below the current limits. We thus offer an alternative that is environmentally friendly.


Orión offers the possibility to turn biomass into energy by using a simple process and the latest market technology.

Through a gasification process, the cellulose is turned into lighter hydrocarbons, including carbon monoxide and hydrogen. This gas mixture, called synthesis gas or “syngas”, has a lower heating value (LHV) that is equivalent to one sixth of the LHV of natural gas when air is used as the gasifying agent. The gasification process relies on the fluidized bed process, in which the gasifying agent keeps an inert gas and the fuel in suspension until the particles of the latter gasify, turn into volatile ashes and are entrained by the flow of syngas.

The biomass undergoes a four-stage process:

  • An initial heating stage up to 100º C to dry out the biomass by evaporating its water content.
  •  The second stage, pyrolysis, also absorbs heat and is when the large molecules are broken down into shorter chains that, at the temperature of the reactor, are in the gas phase.
  •  The third stage is reduction in the reactors by combining the water vapor produced in the first stage with the carbon dioxide that is entrained in the current.
  • The final stage is the oxidation of the heaviest (carbon) fraction of the biomass when it comes into contact with the gasifying agent (air, oxygen or water vapor).


The energy recovered depends on the type of material input into the process: wood waste, ligneous or grassy farming waste, energy crops, etc.
