Environmental Performance

Energy Management

During 2017, the different activities and processes carried out by the Company demanded an energy consumption of 4,963,507.73 Gigajoules (GJ), coming from both the own generation (direct consumption) and its acquisition from other companies (consumption). indirect), and distributed as follows:

Energy consumption per barrel processed

GJ / bbl
GJ / bbl
GJ / bbl
GJ / bbl
GJ / bbl
Talara Refinery 0.218 0.203 0.223 0.252 0.210
Conchán Refinery 0.125 0.131 0.134 0.128 0.141
Iquitos Refinery 0.107 0.109 0.123 0.117 0.110

It is important to specify that our energy matrix is mostly composed (85.99%) of natural gas and other process gases that are reused, as shown in the following figure:

Water Management

During 2017, the total volume of water consumed by PETROPERU, in its activities, was 1,670,016.62 m3, from the following sources:

Water consumption disclosed by type of source

SOURCE Year 2017
Main Sources
Municipal supply or from other company 1,326,824.35 Supplied by the public network, with EPS Grau and ACCIONA-Agua being our main suppliers for the Talara Refinery.
Underground water 131,619.26 Extracted from underground aquifers in some of the stations of the North Peruvian Pipeline and the lagoon of the Conchán Refinery.
Water coming from rivers and creeks 211,573.01 Caught mainly from the Marañón, Amazonas, Itaya and Huallaga rivers.
TOTAL WATER USE 1,670,016.62  

In all cases, the extraction of the water resource is adjusted to the authorized volumes and to the water rights that the Company has. Therefore, it is important to note that none of the natural sources mentioned above is affected, qualitatively or quantitatively, by the collection of water.

It should be noted that at Talara Refinery, most of the water consumed comes from a reverse osmosis desalination plant operated by ACCIONA-Agua. By obtaining and processing salt water directly from the ocean, we avoid taking it from sources of fresh and potable water, thus reducing the pressure exerted by our activities on the already scarce water resources of Northern Peru and increasing their availability for society.

Emissions of greenhouse gases

During 2017, as a result of our different activities, we released a total of 329,613.41 tCO2e into the atmosphere, both from our own sources (direct emissions) and from the acquisition and consumption of energy by a third party (indirect emissions), which in general, it meant a decrease of 19.56% with respect to our 2016 emissions.

Gas Burnt at the Torch

A source of emissions specific to the oil industry comes from the controlled burning of gases by torches, as a safety measure in hydrocarbon refining activities.
During 2017, the operation of these equipment involved the burning of an amount of gas up to 23,220.59 barrels of oil equivalent (BOE).

Waste and effluent management

Solid waste

The amount of solid waste generated by our activities in 2017 was 83,999.55 tons, distributed, according to their risk condition, as follows:

Solid waste generation

Main residues
Hazardous solid waste 77,947.96 Oily muds, land impacted with hydrocarbons, spent catalyst, mineral wool, insulating fibers and electrical and electronic equipment.
Non-hazardous solid waste (organic) 2,321.77 Domestic waste and those caused by the movement of land.
Non-hazardous solid waste (inorganic) 3,729.81 Metals, glass, plastic, among others.

In general terms, in 2017 we recorded a 51.84% decrease in the amount of solid waste generated, mostly hazardous, compared to 2016.

Solid Waste Disposal

Hazardous solid waste, mainly oil slicks, hydrocarbon-impacted land, spent catalyst, mineral wool, insulating fibers and electrical and electronic equipment; they are arranged, according to the Law, in security landfills duly authorized by the General Directorate of Environmental Health (DIGESA), guaranteeing environmental management and sanitary safety of them.

It is important to mention that, in the case of Talara Refinery, the final disposal of most of the hazardous solid waste is carried out in the «Milla Six» Landfill, owned by PETROPERU, which is duly registered and authorized to execute the confinement of these residues.


The management of effluents in PETROPERU is developed at the level of the operations and is part of the current quality and emission regulations. Wastewater is monitored continuously and the results obtained for each parameter are reported to the corresponding sectoral and oversight authority.

Materials Used

The main materials used in the different PETROPERU production processes are processed oil and consumed fuels.

Oil used

The processed oil includes both that which is refined by our refineries, and that which is transported by the North Peruvian Pipeline from the Selva to the Bayóvar Terminal, according to the following distribution:

During 2017, the volume of refined crude remained almost constant with respect to 2016 levels.

Fuels consumed

As for the fuels consumed, these are used by the different equipment, machinery and vehicles that are owned by the Company.

During 2017, the total volume of fuels consumed by PETROPERU was 3,017,493.09 gallons of liquid hydrocarbons and 122,668,471.68 cubic meters of gaseous hydrocarbons, distributed as follows:

10,158.62 gal
Used by our light vehicle fleet.
1,292,348.47 gal
Used by trucks, trucks and heavy machinery, as well as generators, motor pumps and other stationary equipment distributed in all our operations.
1,714,986.00 gal
Consumed by the equipment of the primary distillation unit of Selva Refinery.
71,436,418.78 m3
Used by the ovens and cauldrons of Talara Refinery and Conchán Refinery.
51,232,052.90 m3
Used as a mixture gas by the furnaces and cauldrons of Talara Refinery and Conchán Refinery.
Responsibility over our Products

The environmental impacts of our products depend of different interdependent factors, such as the quality of the fuel, the technology of the equipment used in their combustion and their maintenance condition. In general terms, at a global level the efforts have been focused in reducing the content of sulfur in all the fuels and indeed the elimination of led in vehicular gasoline. In line with that, since 1998 we substituted the use of Tetra Ethylic Lead (TEL) as an additive for gasoline. Currently, all of our gasohols are free of lead, and element that damages the environment and affects the health of people. Similarly, since 2013 we eliminated the use of organometallic compounds with a manganese base in the formulation of our 90, 95 and 97 octane gasohols. The sulfur content in our fuels is also the matter of constant concern. For that reason, eventhough the current regulations establish at maximum sulfur content of 2000 ppm for gasohols, our technical specifications set the limit of 1000 ppm, although the samples tested to date are even considerably lower than said limit, as can be seen in the following figure below:

Similarly, diesel B5 sold by PETROPERÚ presents a sulfur content significantly below that the one established by the national technical specifications (Ministry Resolution N° 165-2008-MEM/DM and Supreme Decree N° 025-2005-EM), with an average content of 2197 ppm compared to the 5000 ppm of sulfur indicated as the maximum specification.

In compliance with the current regulations, in the departments of Ancash, Apurimac, Arequipa, Ayacucho, Cajamarca, Cusco, Huánuco, Huancavelica, Ica, Junín, Lambayeque, Lima, Madre de Dios, Moquegua, Pasco, Puno and Tacna, as well as the Constitutional Province of Callao, we sell diesel B5 S-50 with a maximum sulfur content of 50 ppm, which significantly reduces the emissions of SO2 (sulphur dioxide) into the atmosphere, for the benefit of both, the environment and the health of people.

Use of Biofuels

Since 2009, the gasoline and diesel sold by PETROPERÚ are manufactured using a percentage of biofuels which is now of 7.8% by volume of carbureting alcohol for gasolines and 5% by volume for biodiesel B100 for diesel. The commercial names of said products are gasohol and biodiesel B5, respectively. The biofuels required for the manufacture of gasohols and diesel B5 are acquired in the local and international market (Argentina, Ecuador, Spain, Holland, the Netherlands and Panama), using to that the specifications approved by the Central Product Quality Committee of PETROPERÚ.


Our fuels are sold and delivered through the different sales plants of the refineries and in the terminals/supply plants. This transfer is done through bulk deliveries on hired tanker trucks, barges, tanker ships and/or train cars, which is why the products don´t require packaging of any kind.
