<div class="feed-description"><p>Over 90% of the basic power supply in Estonia is provided by oil shale firing thermal power plants. Oil shale mining and processing generate vast amounts of by-products that are mostly deposited coursing environmental impacts. Estonian oil shale (OSA) is characterized by a high mineral matter. After combustion 45–48% of the oil shale is left over as ash, producing about 5–7 Mt of OSA annually. Despite numerous studies only a small amount of OSA is currently recycled - around 3% of the annual amount produced. Eesti Energia (EE) concern moving towards to environmental sound production set a goal to find solutions to maximise the utilisation of OSA and minimise the deposition at the landfill.</p> <p>Due to its chemical content OSA could be considered as a valuable binder material, which could be used to improve stabilization and strength of civil-engineering structures. Based on these assumptions in the year 2010 the OSAMAT project was initiated. The project aimed at introducing, testing and promoting advanced methods of using OSA as a valuable material in road construction. The project results are intended to serve as basic data for the European policies and local regulation concerning waste recovery to promote sustainable recycling with a focus on life thinking and development of recyclables market. <br /><br />The project was managed by coordinating beneficiary Eesti Energia AS - the largest company in the world producing energy from the oil shale.Associated beneficiaries were EE daughter company Eesti Energia Narva Elektrijaamad AS and construction company Nordecon AS.&nbsp;The project was co-financed by Estonian Road Administration.<br /><br />OSA was tested in construction of the two pilot sites in two construction technologies: road base courses layer stabilization (Narva-Mustajõe pilot site) and mass stabilization of peat (Simuna-Vaiatu pilot site).<br /><br />The OSAMAT project demonstrations&nbsp;are presented in two videos. <br /><br />The shorter video brings the details of the mass-stabilisation of the peat in Simuna-Vaiatu pilot site.<br /><br /><strong><span style="color: #333333; font-size: small;">{youtube}oP8d7pSl-88{/youtube}</span></strong><br /><strong><br /></strong>The longer video gives the information about the both pilot sites construction (including Narva-Mustajõe pilot site construction) and project goals.<br /><br /><strong>{youtube}y4BumQLvKcc{/youtube}</strong></p></div>
