Circularity Micro-Indicators to Building and Construction Sector: Plastic Produ...
Matos, J.; Martins, C.I.; Simões, C.L.; Simões, R.The civil construction sector has been a large contributor for the continuous global increase in the consumption of plastics. However, while the properties of plastics make them very suitable for several civil construction applications, their sustainability is a concern, mostly because current approaches for design and manufacturing do not properly consider their entire lifecycle and end-of-life management. The...
Development of a rapid heat cycle injection molding system using infrared radia...
Simoes, Ricardo; Macedo, Cláudia; Laranjeira, Jorge; Brito, A.M.; Simões, C.L.; Faria, L.Conventional injection molding is widely used to produce plastic parts, mainly in the automotive industry, due to the high production ratios and quality of injection parts. Low mold temperatures are usually employed to decrease cycle molding time and final process costs; however, resulting surface defects include weld lines, sink marks, and warpage. Therefore, plastic parts are often subjected to secondary proc...
Optimization of municipal solid waste collection system: systematic review with...
Neto, Alice; Simões, C.L.; Simoes, RicardoMunicipal solid waste management (MSWM) requires significant planning and objective definitions of each of its stages. Waste collection and transportation stages are of utmost importance, and they represent a significant cost of the process. In this context, a systematic study using bibliometric analysis was conducted, seeking to identify and understand the applied methodologies and tools, as well as which para...

Matos, J.; Martins, C.I.; Simões, C.L.; Simões, R.O setor da Construção Civil é um dos maiores contribuintes da atualidade para o aumento continuo no consumo global dos plásticos. No entanto, apesar das propriedades dos plásticos se adequar a várias aplicações neste setor, a sua sustentabilidade é uma preocupação, principalmente porque as aplicações plásticas atuais são projetadas e fabricadas sem uma prudente reflexão sobre o seu ciclo de vida e a sua gestão ...
