- Qualitative analysis of the limestone waste potential from the Serra de Aire e Candeeiros quarriesPublication . Monteiro, S. M. C. S.; Jorge, Muanassa; Oliveira, N. S.; Alves, M.L.; Veiga, A.; Silva, A.The mountains of Aires and Candeeiros are part of the Maciço Calcário Estremenho where the landscape is predominantly made up of limestone. The limestone explored in the region has been the driver of social and cultural development, contributing significantly to the local economy. This emerging concern has motivated public and private organisations to develop solutions to improve the sector's sustainability. The present work aims to evaluate the limestone waste potential to produce precipitated (PCC) and ground (GCC) calcium carbonate in the region by surveying the local extraction industries that fulfil the defined minimum requirements to produce high quality PCC and GCC. The results allowed to stablish an estimate of the amount of waste resulting from the extraction process. The conversion of these wastes into PCC or GCC constitutes a possibility of recovery into by-products, allowing use in noble and profitable applications and contributing to the circular economy and the sustainability of the sector.
- Risk Communication for Decision-Making: The Role of Community-Contact, Nature-Positive Outcomes, and Risk-PerceptionPublication . Silva, DorindaAppropriate risk communication is extremely important to ensure stakeholder engagement and avoid fatigue, disengagement and inaction. Research shows that promotion of good news is likely to engage stakeholders and inspire action. Thus, to support properly informed risk communication and decision-making truer perceptions of risks and benefits are needed to enable nature-positive and community inclusivity outcomes. Environmental scientists are now tasked with promoting communication for decision making using methods that weigh harm caused against benefits delivered. Currently we face many planetary threats including from climate change as well as the influx of synthetic chemicals. Creating a nature-positive future in the face of these challenges requires positive messaging, measures, and metrics to guide, plan, assess and communicate regenerative development outcomes beyond toxicology, risk and damage assessment. As various stakeholders perceive risks differently it is of paramount importance to understand and predict how non-experts will react to risk, since the majority of this group are often not aware of the threats faced. Very often a lack of consideration is given to risk perception and behaviours across different stakeholders. Likewise contact with communities is challenging but can help to bridge the gap from scientific discovery to valuable knowledge translation into society, related to environmental risk. The session aims to clarify concepts, challenges, and innovative tools and methods for modelling, measuring, and communicating benefits weighed against risk. The session specifically focuses on accelerating restoration, climate security and preventative measures that have successfully been used to protect the environment and human health from harmful chemicals. Moreover, results of community engagement approaches will be presented allowing the possibility to discuss the associated opportunities and challenges of these communication strategies. Presentations should focus on case studies where community-engagement, nature-positive outcomes, and risk-perception are used to support risk communication for decision making, especially in the presence of limited or conflicting evidence. The session will disseminate valid policy, planning and communication tools and methods across various stakeholders including academics, NGOs, industry and policy makers and overall foster knowledge transfer across groups to deliver and manage regulatory solutions.
- Sustainability Assessment of Building Rehabilitation Solutions: The Mid 70s Portuguese BuildingPublication . Reis, Alexandre; Heleno, Lizete; Monteiro, Silvia; Oliveira, Nelson S.The Energy Performance of Buildings Directive (EPBD) establishes improvements to buildings’ comfort conditions and energy performance, bringing them closer to buildings with almost zero energy needs, namely the Nearly Zero Energy Building (NZEBs). The assessment tools for sustainable construction, more recognized internationally, are LEED and BREEAM, and in Portugal is the LiderA. The application of those tools promotes energy efficiency and decarbonization of buildings, as referred to in the Portuguese Long-Term Strategy for Building Renovation (LTRS-PT) until 2050. In this case, a house representative of the construction of the period between 1971 and 1980 in Portugal was chosen to evaluate environmental sustainability using LiderA. In the current conditions, the LiderA rating class of the house was D. To improve the performance of the building were identified balanced rehabilitation solutions without excessive automation. The presented solutions should avoid transforming the house into a complicated device with operational difficulties or specialized operation. In this way, the proposed interventions in the building and systems are based on renewable sources, prioritizing energy and water efficiency. Furthermore, as a contribution to the health and well-being of the occupants, we considered measures related to indoor air quality (IAQ) and noise minimization. In addition, the encouragement of native species has contributed to ecological enhancement. With that proposals, the house rating class using LiderA improved from class D to class A+.
- Sustainability Performance of Buildings in the Project Stage—Residence StudentsPublication . Heleno, Lizete; Baptista, Pedro; Marta Gregório; Oliveira, Nelson S.; Monteiro, SilviaIn recent years, the concept of sustainable construction has been promoted by demand and by regulations. Several methodologies to assess the sustainability of the construction have been spread across the world, by several countries for almost all continents. This study focuses on the most used construction sustainability assessment methodologies, which were compared with the Portuguese methodology, LiderA. It was found that the LiderA is the sustainability system with the greatest number of relevant criteria, considering the three dimensions of sustainability, environment, economy and social. Considering the 5 phases of the construction life cycle, the importance to apply these methodologies in construction is crucial in the early phases. It can help to draft the sustainability classification of the building. To apply the LiderA was used a residence of students, a building composed of apartments, in the phase of planning. All of the 40 criteria from the LiderA were classified from F to A++, according to the project of the residence of students. The final classification, as it was projected, was A, meaning that the building has an environmental performance 50% higher than usual practice. The category of criteria with the highest contribution was the category of quality of service and resilience, with a percentage of achievement greater than 50%. The local dynamics and the resources category were the categories with the lowest contribution, and they have the potential to be reevaluated by the building promoter, since it has the potential to improve the sustainability classification of the residence of students.
- Sustainability study of limestone quarry waste into value-added products: PCC and GCCPublication . Monteiro, S. M. C. S.; Jorge, Muanassa; Heleno, M. L.; Oliveira, N. S.; Alves, M. L.; Veiga, A.; Silva, A.Calcium carbonate can be obtained naturally from limestone, chalk, marble, and other sedimentary rock forms. Ground calcium carbonate (GCC) and precipitated calcium carbonate (PCC) are two materials that can be produced from natural calcium carbonate. The future of GCC and PCC is promising since they are linked to industries with high demand, such as packaging, building & construction, transportation, and industrial applications, with an expected compound annual growth rate higher than 4% until 2027. This research focuses on the production of GCC and PCC through a comparative analysis that identifies the macro conditions that become advantageous to produce and commercialising PCC in a quarry context. This allows a valorisation of the limestone waste resulting from the extraction operations, converting it into by-products of the process. Not all existing limestone quarries in the Serra de Aire e Candeeiros region are suitable sources of raw material to produce PCC. The five extraction poles were identified with the potential for extracting suitable raw materials, associated with several companies dedicated to the extraction operation in these quarries.
