Energy Efficiency and Renewable Energy in Industrial Sectors

Globally the industrial sector is responsible for around one-quarter of total energy consumption. The industrial sector spans a wide variety of activities. While the energy saving potential in industrial application regularly exceeds 30% (except for very modern production plants), finding the most efficient solutions for reducing energy consumption is often a complex task.

LEEREFF offers loans for standard technologies and for non-standard projects. Both approaches can be applied in industrial energy efficiency projects:

Standard Technologies:

LEEREFF has developed a list of standard technologies, which includes pre- approved devices, such as compressors, lighting, motors, Solar PV, etc. For simple energy efficiency improvements in production facilities, the list offers a wide variety of solutions.

Non-standard projects:

Industrial complexes often require improvements in their production facilities. While machine replacements can produce substantial energy savings, it is advisable to combine these (often high) investments with a more complex review of energy saving potential throughout the process. For example, consider a new machine being connected by conveyors with other process steps. Are the conveyors equipped with the most efficient motors and/or are the motors fitted with variable speed drives, which can easily produce energy savings in excess of 50%? For non-standard projects, you can get free technical advice from the LEEREFF team of engineers As a general note, access to energy is the life-blood of all manufacturing industries, but energy is often in short supply in Lebanon.

Consider making your own energy: factories generally have large roofs. These can be perfect for rooftop solar PV installations. Why not replace part of the energy purchased off the grid by solar energy produced on your roof? The benefits include cost savings AND improve your security of energy supply.

Mini Case – Printing

A printing company with the capacity to produce 8,000 square meters 
of printed materials undertook a simple energy audit to improve its energy consumption. Resulting from the consultants’ recommendations, the company made the following improvements:

  • Compressed Air – installed a properly 
sized air compressor, delivering the required 6 bar instead of 10, saving approximately 23% of energy 

  • Installed LED lighting throughout ad saved more than 60% on lighting energy 

  • Replacement of HVAC system reduced system related energy consumption by 30% 


Mini Case – Metal Processing

A large metal processing company with the production capacity of three thousand reinforced concrete units per month invested in optimizing the energy efficiency of its plant. The project consisted of installation of new press scissors to reduce operational costs and energy consumption in the melting furnaces, decentralization of compressed air system, heat recovery and automatic control systems. The investment resulted in annual energy savings of 30,000 MWh per year and also reduced production wastes and
