Milaki Plant

The Milaki plant is located nearby Aliveri in South Evia. It was founded in 1982 and is the most modern plant of Heracles, with an annual cement production capacity of 2.2 million tons.


The production line design and the technology applied to process control, from raw materials processing to end product, have enabled the Milaki plant to respond to international market requirements for specific standards cement.


1982: Operation start-up

1983: Vertical cement production is launched

1998: Investments for full automation of production

2001: Burning system is upgraded

2003: Covered storage area for raw mix pre-homogenisation

2007: Hybrid technology filter installed in the production line of the plant to minimize dust emissions

2007: Continuous Emissions Measurement System (CEMS) installed to record emissions constantly 

2007: A new clinker storage silo is constructed featuring an automatic handling system, to eliminate open-air storage and reduce fugitive dust

2008: Infrastructure and environmental improvement works at the plant port to reduce fugitive dust

2008: Installation of system to cut down NOx emissions


Committed to sustainable development

Milaki plant is greatly evolving and improving the last years. The commitment of the plant and its people is crucial for the success of Sustainability Ambitions 2012, Heracles roadmap for sustainable development. The program is focusing on improving the Health and Safety of our employees and local communities, decreasing of our environmental footprint and ensuring a sustainable operation.

Health & Safety: top priority

Health and Safety are to Heracles fundamental values and key priorities in every activity. The company implements the Lafarge Group Health and Safety policy, which was signed in 2006 and tolerates zero accidents.


The Milaki plant, with collective effort undertaken these past years, has significantly improved. Constant progress in Health and Safety is a daily top priority. Heracles has taken measures relating to the necessary personal protective equipment, infrastructure works for a safe workplace, implementation of standards and procedures for every work performed as well as training and behavioral programs fostering and establishing a shared safety culture within the organization. More than 3,000 training hours on an annual basis are dedicated to Health and Safety, out of a total of 7,300 training hours for Milaki employees.

Improvement of environmental performance

In the context of Heracles' Sustainability Ambitions 2012, the Milaki plant has been implementing an action plan associated with the plant's long-term improvement and response to challenges, such as climate change, preservation of natural resources and biodiversity protection. Apart from the action plan under the Sustainability Ambitions 2012, the Milaki plant has reviewed the specific conditions of its geographic location (proximity with residential area) and geomorphology (winds, altitude difference between the plant and Milaki community), in order to control its environmental footprint.


For the reduction of dust emissions, the plant installed in 2007 a hybrid filter in its production line, covering requirements far beyond than current industry standards. The hybrid filter minimizes stack dust emissions and performs regardless of temperature, moisture and external conditions. Additionally, an automatic stack gas analyzer, Continuous Emissions Measurement System (CEMS), was also installed.


The plant has adopted an extensive program of measures to decrease fugitive dust throughout the handling processes, from raw material to final product. Limestone is transported from the quarry to the plant on a covered conveyor belt and stored in a 50,000 t. silo. Raw materials are pre-homogenized in a covered storehouse, with a 30,000 t. capacity, built in 2003. The clinker is transported from the kiln and stored using an automatic handling system. The works completed at the plant's port in 2008 reduced fugitive dust during the handling of the final product.


In addition, a special study has been elaborated regarding the construction of wind barriers around the solid fuel storage area, which will lead to a great reduction in fugitive dust emissions.

Quarry rehabilitation

Milaki plant has two quarries in the greater region: in the area of Boyiatzaki for limestone and in the area of Katakalou for schist. The objective of any quarry rehabilitation is to deliver to the community an area with enhanced biodiversity, depending on the pre-intervention its condition and improve the landscape following the intervention. For the plant's quarries rehabilitation more than 200,000 trees and bushes of local flora have been planted.

Know-how and high specialization

All cement production stages require high technical skills, strict adherence to procedures and strong team spirit. With continuous and intensive training programs, the plant ensures its employees' development and capacity build.


The plant facilities are fully automated and centrally controlled from the control room. Specialty operators supervise the overall operation of the plant, oversee facilities and make the necessary arrangements in the production process. The continuous monitoring of its environmental performance leads to respective improvement. The dust and gas emissions are measured and analyzed, giving complete control of the process and allowing efficient and timely response.

High quality control

The Milaki plant applies high standards of quality control. It is certified as to the ISO9001:2008 quality assurance system and all types of cement produced are certified in accordance with the mandatory European cement standard EN197-1 and bear the CE marking.


The plant is also certified as to the ISO 14001 Environmental Management System and the OHSAS 18001 Health and Safety System.


Contribution to the economic and social development

The Milaki plant with its operation has a major contribution to the economic and social development of the region.


During the period 2004-8, 28.3 million euro was invested for upgrade projects. 14.8 million euro (more than 50%) was dedicated to safety and environmental projects.


It offers on an average annual basis 17 million euro in salaries and employees' wages.


The total of salaries, employees' wages, supplies, taxes and support of local programs or sponsorships is on average 22 million euro.


Milaki plant is interested in your feedback or any questions that you may have.

Enhanced Cements

Heracles GCCo, pioneer in the differentiation of cement products in the Greek market, offers to the market the new enhanced reactivity cement series HeraclesTM Ενισχυμένο and BasisTM Ενισχυμένο. Driven by innovation for the development of materials and solutions for the construction sector, Heracles has implemented, for the first time in Greece, the innovative technology of separate grinding in the cement production. 

Industrial ecology

How to create value from waste

Large amounts of natural resources, particularly minerals and fossil fuels, are used to manufacture cement. For many years the Group has been working to reduce the environmental impact of its activities by finding ways to obtain value from waste products.
