- Morphology and Thermal Behaviour of New Mycelium-Based Composites with Different Types of SubstratesPublication . Alves, Rafael M. E.; Alves, M.L.; Campos, Maria J.The need for new green and sustainable materials has been fostering the development, research and introduction of biodegradable materials from natural and renewable sources. Commercially available biodegradable plastics, while minimizing their environmental impact and exhibiting a set of properties that enable the obtainment of industrial components, usually require complex processing methods, are costly and have limited applicability. A new growth of natural resources based paradigm applied as production process is increasing its relevance as an alternative production process. New materials that combine fungal mycelium with waste materials as coffee grounds or wood waste can be considered as promising to fulfill this new paradigm. This new biomaterial mycelium based composites present controllable and adjustable properties during their growth, being able to grow and penetrate organic substrates, thus forming a tangle of branched fibers and a structure that presents some thermo-mechanical properties similar to the ones of plastics. The aim of the present study was the selection of the optimal inoculation temperature, light, humidity and the best substrate for the fastest and consistent mycelium growth. Four types of mycelium were incubated, namely Pleurotus ostreatus (382), Hypsizygus ulmarius (420), Ganoderma lucidum (560) and Trametes versicolor (620). The influence of the three substrates (coffee grounds, pine waste and general wood waste) on the growth was analyzed both morphologically and thermo-mechanically by means of differential scanning calorimetry (DSC) and X-ray micro computed tomography (microCT).
- Sustainable tourism and the circular economy: A theoretical overviewPublication . Costa, Berta; Rodrigues, Susana; Moreno, PilarThe concept of sustainable tourism has become one of the most noteworthy topics among academics and practitioners and a hallmark in tourism discourse. During the last decades, tourism has developed into one of the largest socio-economic activities, and thus driving economic growth that most supports to the countries’ GDP (Gross Domestic Product). The world economic paradigm, and consequently the tourism industry, is configured according to the linear model of production and consumption, in which goods are discarded after usage, resulting in massive waste. Furthermore, the degrading impact of tourism, along with the assumption that natural resources are abounding, and that environment has unlimited means to absorb waste, need to be addressed without delay. Considering these premises, the principle of sustainable tourism arose with the objective of minimizing the negative effects of tourism related activities. From this standpoint, circular economy emerges as a solution, as it harmonizes economic development with the sustainable use of natural resources, and also enables the tourism industry to become more sustainable. The purpose of this article is to outline the conceptual dimensions of sustainable tourism and circular economy, and also scrutinize how these two constructs have evolved over the past decades and their correlation. A broad literature review was conducted, in order to draw attention to the constituent elements brought to discussion.
- XVI International Symposium on Marine Natural Products|XI European Conference on Marine Natural ProductsPublication . Pedrosa, Rui; Gaudêncio, Susana P.; Vasconcelos, VitorThe International Symposium on Marine Natural Products (MaNaPro) happened for the first time in 1975 in the city of Aberdeen, Scotland, organized by Professor Ronald H. Thomson. The European Conference on Marine Natural Products (ECMNP) occurred for the first time in 1997 in Athens, Greece, organized by Professor Vassilios Roussis. The MaNaPro and ECMNP conferences have triennial and biennial frequencies, respectively. Since its first edition, the ECMNP has been set in the alternating years of the Gordon Conferences on Marine Natural Products. In 2019, it was the second time, in 44 years, that a joint organization of the MaNaPro and ECMNP meetings occurred. The first joint meeting of the MaNaPro and the ECMNP occurred in 2013 in Galicia, La Toja, Spain, organized by Dr. Carmen Cuevas from PharmaMar. Over the time, there have been 16 editions of the MaNaPro and 11 editions of the ECMNP held in several countries.
