Abstract

ABSTRACT This work tackles the development of green biocomposite insulating panels out of fungi mycelia and to replace petroleum-based foam-expanded polystyrene (EPS) panels. These biological prototypes have advantages over expanded polystyrene foam panels, since they do not pollute, they are not flammable, and they are 100% biodegradable. They have been developed growing Pleurotus ostreatus (oyster mushroom) and Lentinula edodes (Shiitake) mycelia on different agricultural substrates inside different types of moulds (up to 21 × 30 cm). As a result, the most suitable combinations of fungi species and agricultural substrates have been determined to grow biological insulating panels. Prototypes obtained were subjected to accelerated ageing tests to evaluate their resistance and changes in durability against water filtration and humidity changes in the event that they are used as insulating panels. Some technological properties have also been determined to evaluate their use as construction materials. The results obtained allow us to claim that biodegradable fungi-based insulating panels are viable to replace polluting foam-based insulating panels for the construction industry.

为建筑行业种植真菌基可生物降解隔热板的程序

摘要:本研究旨在开发一种由真菌菌丝制成的绿色生物复合隔热板，以取代石油基泡沫膨胀聚苯乙烯(EPS)板。这些生物原型比膨胀聚苯乙烯泡沫板有优势，因为它们不会污染，不易燃，而且是100%可生物降解的。在不同类型的霉菌(最大可达21 × 30 cm)内，在不同的农业基质上培育出平菇和香菇菌丝。因此，已经确定了真菌种类和农业基质的最合适组合来生长生物隔热板。获得的样品进行了加速老化试验，以评估它们在用作绝缘板的情况下对水过滤和湿度变化的抵抗力和耐久性变化。还确定了一些技术性能，以评估其作为建筑材料的用途。所获得的结果使我们能够声称可生物降解的真菌基隔热板是可行的，可以取代污染的泡沫基隔热板用于建筑行业。

期刊介绍： The purpose of the Journal of Green Building is to present the very best peer-reviewed research in green building design, construction, engineering, technological innovation, facilities management, building information modeling, and community and urban planning. The Research section of the Journal of Green Building publishes peer-reviewed articles in the fields of engineering, architecture, construction, construction management, building science, facilities management, landscape architecture, interior design, urban and community planning, and all disciplines related to the built environment. In addition, the Journal of Green Building offers the following sections: Industry Corner that offers applied articles of successfully completed sustainable buildings and landscapes; New Directions in Teaching and Research that offers guidance from teachers and researchers on incorporating innovative sustainable learning into the curriculum or the likely directions of future research; and Campus Sustainability that offers articles from programs dedicated to greening the university campus.
