INTRODUCTION
Within the scope of a cooperation contract between LNEG and the Technological Center for natural
marble (CEVALOR), this entity promoted a joint project for the application of Sustainability concept,
involving eight companies working in marble extraction and transformation, in Alentejo region.
The Sustainable Value of manufacturing process in
Alandromar increased 14%, as a result of performance
improvement and resources reduction. Environmental and
social aspects were improved namely in what concerns
image and workers safety.
METHOLOGY
The methodology used in the project supported the eight companies in the improvement of their
Sustainable Value, by implementing in their processes the Cleaner Production and Value Analysis
approaches, in an integrated way. In all the involved companies, this strategy improved the relationship
between economical, environmental and social performance and the use of resources, thus leading to
the improvement of their eco-efficiency and competitiveness, based in an innovation entrepreneurial
culture.
The training / implementation methodology empowered the eight companies with new knowledge and
was based in training workshops followed by the development and implementation of Sustainable Value
projects in the companies. For this purpose the Sustainable Value manual was used in each company
by a team which included elements from the company, technicians from CEVALOR and was tutored by
LNEG (ex INETI) team.
Marmetal main activities are marble extraction and waste
processing and valorization. 33% of performance
improvement, 9% of costs reduction and 45% of
Sustainable Value increase were the results obtained.
Performance
Satisfaction of needs
Lamármores found a solution for the problem of water
availability during shortage periods. The working
conditions and the company’s image were improved, the
cutting process productivity was increased and the
manufacturing process was optimized. This led to an
increase of 2, 5% in Sustainable Value.

1. General data from
the company
2 . Specific data about
the project
3. Global inventory
(diagnosis)
• Identification, Labouring conditions, Staff flow chart, Relationship with
stakeholders
• Study subject, Working team, Objectives, Constraints, Information about the
product (market)
• Manufacturing diagram, Operations description (Raw materials, Water,
Energy, Products, Waste, Noise…), Mass and energy balance, Cost diagram
4. Functional Analysis
• Functions listing, Function characterisation, Function weighting, Cost/
Function relation, Sustainable Value
5. Problem Synthesis
• Process eco inefficiencies, Environmental incidences, Legal non conformities,
Functions and parts with high costs, Non balanced cost/performance relation
6. Previous
identification of ideas
• Creativity, Solutions searching
7. Viability analysis
• Technical, Environmental, Economical, Sustainable Value
8. Action Plan
António Galego e Filhos’s objective was to compare
Sustainable Value in the older cutting machines (Simec and
Mapor) with the Value in the recently purchased ones (Pedrini).
Pedrini machines showed a higher Value than the others.
Marmoz studied marble extraction processes in Rosal quarry
and its processing into standard tiles. By implementing 7 of the
developed ideas the performance level increases 19% and the
involved resources decrease 6%. The company Sustainable
Value increases 27%.
• Action Plan proposal to Top Management decision
Marbosserra attained 10% of improvement in Sustainable Value
resulting from ideas dealing with good housekeeping (81%),
material substitution (5%), internal valorization (5%) and product
changes (9%).
RESULTS
CONCLUSIONS
At the end of the project each company presented
those results, in a public session, where the eight
involved companies participated together with others
from the mineral extractive industry, which could be
interested in a future application, universities, public
and private entities.
The companies involved in this
project integrated in their
entrepreneurial
culture
this
approach with the aim of
maximizing their Sustainable
Value. By doing so they initiated
an irreversible improvement
process
in
which
the
environmental
and
social
aspects of their activities
together with the economical
ones will be taken into account.
This will contribute to the ecoefficiency of mineral extractive
industry and to the sustainable
development of the sector.
Some results that can be pointed out:
Reduction in the consumption of energy, auxiliary materials and
water losses and in the contribution for greenhouse effect were
achieved at J. M. Nobre. Workers safety in the quarries as well
as the company’s image were improved.
Marbrito developed ideas mainly having to do with sheets and
orders manufacturing. Sustainable Value increased for all of
them.
• Environmental diagnosis of manufacturing
processes;
• Energy consumption characterisation;
• Reduction of materials, energy and water
consumption;
• Reduction of toxic dispersion
• Waste preventive approach;
• Cost identification and reduction;
• Company eco efficiency improvement;
• Company competitiveness improvement;
• Internal and external communication improvement;
• New competences development in companies and
Cevalor;
• Health and safety procedures awareness;
• Adoption of more social responsible behaviour by
the companies;
• Sustainable Development increase.
