Objective Action

Elimination of the production of rolling oil waste from the production process

 

Target Audience

Technicians/ engineers/ scientists dealing with waste management and resource recovery – utilisation

 

Duration

2016-2017


Description

Large amounts of rolling oils are needed for aluminium foil rolling. They are used for the creation of a lubrication film between the foil sheet and the working rolls. Due to their stringent quality specifications and the severe impact on aluminum foil surface quality, rolling oils are almost intolerant to contamination.

Nevertheless, the impurities of the rolling oils by the lubrication oil of the rolls is considered almost unavoidable and therefore the complete substitution of the rolling oils, periodically, is a standard procedure.

During this two-year-project, the sealing of the rolls’ bearings was fully redesigned and the new gaskets were made of special, advanced technology materials.

As a result, the contamination of the rolling oils was eliminated and the substitution of the rolling oils is not necessary anymore.

In the first phase (2016) the rolling oil waste was reduced by 88%, from 3,88kg of waste per aluminium tn produced (average of last five years before the project) to 0,47kg of waste per aluminium tn produced.

In the final phase (2017) the waste was completely eliminated and 165tn of rolling oil waste are now avoided per year thanks to this project.

Impact on Society

The results of the project are mainly related to environmental protection and resource utilization.

In the first phase (2016) the rolling oil waste was reduce by 88%, from 3,88kg of waste per aluminium tn produced (average of last five years before the project) to 0,47kg of waste per aluminium tn produced.

In the final phase (2017) the waste was completely eliminated and 165tn of rolling oil waste are now avoided per year thanks to this project.



Initiative Location

Symetal – Oinofyta Rolling Plant


Working with Organization

No cooperation with other associations


Workers Participation

The project was assigned to a maintenance department team that worked alongside with production department.


Benefits for Οrganization

The implementation of the project has helped Symetal achieve significant benefits both for the Company itself and for the environment, as it has contributed to the elimination of a particular waste (rolling oils) from the Company’s production process.

165tn of rolling oil waste are now avoided per year thanks to this project, which results in:

• Economic benefit for the Company, as there is no need for waste management and for waste disposal for recycling purposes. Moreover, productivity due to time spent on oil replacement is not reduced, while the quality of the final products is improved.

• Environmental benefit, as neither resources for waste management purposes are consumed, nor waste for final disposal is generated.
