This work presents a study on the use of wood and plastic wastes generated in abundance in Merida, Mexico, to help to reduce them in order to mitigate environmental deterioration. The use of these wastes is proposed to obtain a low-cost building material. So, the escalation process (i.e., extrusion) at the pilot level to obtain a prototype of a wood–plastic composite (WPC) corrugated sheet to evaluate the technical feasibility to make a low-cost product is reported. A corrugated sheet with recycled high-density polyethylene (R-HDPE) was produced. The R-HDPE was collected from Merida’s Separation Plant. The wood came from the trimmings of different varieties of trees and shrubs that are periodically pruned. WPC sheets with virgin HDPE were prepared to assess its effect on the materials’ mechanical performance. The wood/HDPE weight ratio was 40/60. The performance of the WPC sheets was compared with that of commercial products with similar characteristics, namely acrylic and polyester sheets reinforced with fibreglass, and black asphalt-saturated cardboard sheets. Thus, the effect of natural weathering on the maximum tensile tearing force and on the maximum flexural load of the different types of sheets was evaluated. Although the mechanical performance of the WPC sheets was lower than that of the acrylic and polyacrylic sheets, their performance was much better than that of the cheap black asphalt-saturated cardboard sheets. So, they are a good option to be used as low-cost temporary roofing.

During a post-earthquake restoration and reconstruction process, a building material project could be initiated to respond the short supply speedily for social welfare. At the same time, the project would be generally profitable but less sustainable. By a case study, a trade-off process pertinent to raw material and manufacturing alternative with a building brick project is explored, and then an environmentally sustainable manufacturing system for meeting building brick demands is revealed by an economic analysis.

A brand represents the essence of the value proposition an organisation extends to the market. It is crucial that brands are nurtured with the goal of trying to establish the brand in a top-of-mind awareness position among consumers. By means of a qualitative case study employing 25 interviews which were analysed by using Grounded Theory coding techniques, the most pertinent factors influencing the Corobrik brand were identified. The greatest challenge facing Corobrik is the growing residential sector. The study highlights how Corobrik has grappled and come to terms with the changing nature of its market, and how it has combined all functional areas, from production to distribution, marketing and finance, in promoting its brand.
