WP-3: Extraction and Demolition Site Level Activities
Challenging targets
• The operational phase of aggregate quarrying runs from the first implementation of a minerals planning permission through to the completion of restoration and immediate aftercare works.
• The most important aspects of minimising the adverse effects of quarrying on the environment with respect to all relevant social, economic and environmental issues in both regional scale and local spatial planning.
• Re-use of quarry by-products produced during the extraction and processing of aggregates.
WP-3: Extraction and Demolition Site Level Activities
Objectives
• (1) decreasing environmental and social impacts of quarrying and improving reclamation,
• (2) reducing illegal quarrying, and
• (3) increasing recycling, which will decrease the use of primary aggregates
WP-3: Extraction and Demolition Site Level Activities
Contribution to SARMa
• Primary aggregates are essential to the continued development and maintenance of infrastructure of housing, industry and transport.
• To ensure their continued provision in a steady and sustainable manner it is essential that aggregate assessment and planning be carried out both nationally and locally in an effective and efficient way.
• Through best practise guiding, control of illegal quarrying and recycling WP3 will contribute to achieve sustainable quarry life-cycles in relation to the entire production chain of planning and design, operational and post-closure phases.
• The benefit of improving the knowledge base at a local level should be highlighted to optimize aggregates extraction at site level.
WP-3: Extraction and Demolition Site Level Activities
Methodology based on 4 activities
• Activities will enhance information available at regional and national levels.
• WP3 starts at beginning of the project because it provides technical information for WP4 and WP5.
• Each activity has mix of partners based on their expertise, with at least six in each.
• Activities will be carried out in parallel and have the same methodology: analysis (case studies), synthesis, evaluations, pilot actions (in some cases), outputs (reports, guidelines, and manual) and results (local to regional events).
• The activities merge at the evaluation stage.• Activity 3.4 develops manuals to be used for capacity
building workshops and other outreach activities in WP4.
WP3 Task Activities
• 3.1: Best practicesedition of manuals/guides/toolboxestowards aggregates sustainability • 3.2: Illegal quarrying good communication, capacity building and stakeholder consultation to achievesocial license to operate • 3.3: Recycling re-use of quarry and demolition wastes. • 3.4: Outreach/CommunicationManuals, workshops etc
Activity 3.1: Environmentally friendly extraction practices (TUC)
Duration: 05/2009-10/2010
Objectives:• a) collect information on best practices and failures
for aggregates extraction, e.g. environmental management, assessment of aggregate resource/uses information;
• b) develop guidelines for post quarrying restoration/land use;
• c) determine impediments to best practice, e.g. lack of knowledge, regulatory blocks;
• d) prepare recommendations for industry and government actions to encourage best practice e.g. LCA study approaches (?)
Activity 3.1: Environmentally friendly extraction practices
Role of each partner
• TUC will lead activity, and partners are IGME, ER, Parma, FGG, MINGORP, and RGF.
• Each partner involved will provide analysis of its own case studies (region) where several quarries will be examined.
• Partners will jointly work on synthesis, evaluation, outputs and results.
• Partners will prepare regional events (Croatia & BiH together, Greece, Romania, Albania, Italy).
Activity 3.1: Environmentally friendly extraction practices
Geographical location
• GR: Laka, Mandalos,Araxos,
• IT : Lanca dei Francesi,
• SP: Fruska gora,
• RO: Iacobdeal, Luminita-Tasaul,
• HR: Terstenik
Activity 3.1: Environmentally friendly extraction practices Description of pilot sites/LAKA-GR
• Type of aggregate: Gravel and sand• Peculiarities: Mainly superficial quartz deposits of particle size ranges,
0.0625 mm<sand<4 mm; 4 mm<gravel<64 mm. Production residues / quarry wastes of mainly clay and silt; inert or non-hazardous; considerable variation in production rates from a few percent up to 30% of total mined material; Quarry by-product fines from sand and gravel pits vary enormously, but production percentages fall within 5 to 15%.
• Justification – why is this site interesting for the project: Re-utilization of an abandoned gravel mine situated in Laka area in the region of Pella. The mine was operable since 1960 until a few years ago but unfortunately it was shut down. The mine has a great significance for the local development. By implementing a pilot action through the activity 3.1, in the framework of the WP3 it will be possible to reach and adopt best practise operations and sustainable management. It should also be mentioned that 1300 hectares of the Laka deposit was subjected to illegal quarrying and needs to be restored.
• Development of a database of legal and illegal quarries and mines.
Activity 3.1: Environmentally friendly extraction practices Description of pilot sites/MANDALOS-GR
• Type of aggregate: Basic and ultrabasic igneous rocks
• Peculiarities: Production residues characteristics with large variation in size, very large oversize blocks and very fine undersize particles; inert / non-hazardous. Igneous rocks produce between 10 to 30% fines.
• Justification – why is this site interesting for the project: The Sustainable Use of High Specification Aggregates for Skid-Resistant Road and Railway Surfacing is of frequent request amongst local stakeholders. The Mandalos quarry is one of the few sites where igneous rock aggregates extraction is in operation.
Activity 3.1: Environmentally friendly extraction practices Description of pilot sites/ARAXOS-GR
• Type of aggregate: Limestone quarry owned by AKTOR, a major construction
company in Greece, which has an observer role in SARMa. • Peculiarities: Production residues composition: similar to rock, but with higher
quantities of chert and clay; some streams may also contain small amounts of vein materials. Variable quantities depending on the local topography and geology; non-hazardous. Limestone quarrying generates around 20-25% fines.
• Justification – why is this site interesting for the project: All available information concerning current operational and production phases as well as related environmental and societal issues of the Araxos limestone aggregates quarry, show that a new more resource efficient sustainable way of management is required.
Activity 3.1: Environmentally friendly extraction practices
Description of pilot sites/Lanca dei Francesi • Type of aggregate: Fluvial sand• Peculiarities: The quarry is located within the Po River
overbanks, in a flat land that can be occasionally submerged during river floods. The quarry started to operate in 2003. The amounts extracted during five years were:1.000.000 m3 of sand and 290.000 m3 of clay.. Restoration included the creation differentiated humid zones. The sand is used in foundries and the clay in tiles. No processing is taking place. The sand goes to the local or provincial market. There is no waste
• Justification – why is this site interesting for the project: In 2007 the Province of Parma applied better restoration of the quarrying sites in the Po river banks according to the regional guide lines. This concerns about 1.250.000 m3 of sand 250.000 m3 of clay
Activity 3.1: Environmentally friendly extraction practices Work to be undertaken on pilot sites
• Geological mapping, and aggregates resource evaluation, potential and sustainability
• Efficiency of Primary Aggregates Production e.g. water & energy consumption, transport
• Extraction vs environmental management and pre-, syn -, and post-quarrying restoration & land use
• Legal monitoring and environmental impacts as viewed by local/regional authorities

3.3. RecyclingDescription of pilot sites/Nerviano Ecoter
(plant 1), Legnano Ecoter (plant 2)
• Type of aggregate: Recycled aggregate• Peculiarities: These two twin plants represent two of
the best aggregate recycling facilities in Italy.The plants are equipped with very high level technology machineries and produce 150 kt/y (each) of CE marked recycled aggregates. They have an internal laboratory to control the quality of the materials produced (6 types of aggregates: 0/6, 0/16, 0/30, 16/30 and 0/70).For the collection on site they developed a special system based on mobile containers sited on the city building yards.
• Justification – why is this site interesting for the project: The recycling centres might represent best practice examples to be exported to other SEE countries.
3.3. RecyclingOptions and tasks to be paid
attention and carried out
• mapping, quantification, characterization, feasibility• providing an overview of production figures and
mitigation practices • valuable alternative materials for use in a variety of
end products, and bound and unbound applications • do not necessarily behave in a way similar to
conventional primary aggregates• need to develop fit-for-purpose specifications • limestone, 20-25%; sandstone 35%; igneous rocks,
10 to 30%; sand and gravel 5 to 15%
3.3. RecyclingDeliverables/Outputs
• Reports on life cycle analyses of aggregates/case studies: GR, IT, SLO, ALB, RO including the whole operational chain of quarry-life (planning and design, and operational and post-closure phases).
• Provision of recommendations for consumer, industry and government actions.
Waste needs a market
• Aggregate, landfill: local market
• Industrial minerals: regional/national/inter-national market (depending on value)
• Armour stone: close to harbour
• Environmental stone: local/regional?
• Easiest for quarries in populated areas!
3.3. RecyclingSustainability aspects
• need for a steady stream of mineral planning permissions for new quarries and for extensions of existing operations.
• need to improve the sustainability of quarry operations in terms of reducing quarry fines production and reductions in energy and water consumption.
• improve aggregate reserve definition by use of better, more accurate, exploration and assessment techniques.
• minimise fines production through carefully selected or modified crushing and screening circuits.
• transport of aggregate from a quarry or other source to the point of use is essential affecting communities in the vicinity of transport routes and infrastructure and the global environment as it is estimated that transport accounts for between 20% and 40% of the total carbon dioxide emissions generated by the aggregate industry as a whole. Alternatives to road transport are limited.
The SARMa project will contribute to improving knowledge and practiceand reducing the adverse environmental effects of transport.
3.4:Outreach/Communication
Objectives
Preparation of a manual synthesizing
reports and recommendations from
each site level activity. It will explain
requirements for and actions needed to
enhance resource efficiency in
quarrying at local level.
3.4:Outreach/Communication
Role of each partner
• All group members will be involved. Manuals will be used in workshops of WP2 and all partners will disseminate them.
