Sibline complies with the Lebanese National Standards for Environmental Quality Protection (dated 01/03/2001). All gaseous emissions (Dust, SOx, NOx, and other organic and non-organic gases) from the main stacks are continuously measured and reported. At present, all emission analyzers at both production lines are of the latest generation (BAT). The mean concentration values of all emissions, including heavy metals and PCDD/F, are at levels below those known from European countries.

By-products are reintroduced during the batching process, thereby eliminating solid waste.

Over the past ten years, Sibline invested significantly on measures to reduce its emissions, primarily by replacing pre-existing electrostatic precipitators (EP) with new state-of-the-art bag houses. In 2013, a new bag house was installed as the main de-dusting unit at production line No. 1. A second bag house was installed in 2016 at line No. 2 in place of the existing EP. An environmental management program was adopted in order to improve the conditions within the plant and its surroundings.


Sibline recognizes the importance of biodiversity in preserving environmental sustainability. It also acknowledges the need to consider environmental and social issues during the execution of our core activities.

We are committed towards building a more sustainable world by embracing the responsibility to reduce our impact on the environment. Sibline has developed strategies for reducing its negative effects on biodiversity, particularly through the implementation of landscape recovery plans and action plans for biodiversity.
Scientific knowledge and applied research are foundations of the landscape recovery process at Sibline quarries.

Alternative Resource

Cement production has greatly advanced in the last few decades. Traditionally, fuels used by kilns in cement production include heavy fuel oil, petroleum coke, coal and natural gas. These fossil fuels are now being replaced partially by alternative fuels (AF). This trend is beneficial to cement producers as well as to society in general.
The use of alternative fuels decreases the drain on the world’s fossil fuel reserves. In particular, if the alternative fuel is a type of biogenic waste, greenhouse gas emissions may be reduced. Using alternative fuels can help decrease the overall cost of cement production.
Sibline has received a temporary permit to conduct refuse-derived fuel (RDF) co-processing trials within its cement kilns. RDF is the selected alternative fuel that will be used alongside petroleum coke.


In order to minimize the environmental impact of quarry operations, a landscape rehabilitation plan was drawn up. The rehabilitation of the quarries began in 2001.
