A Comparison of the Sustainability of Wood and Bamboo as a Structural Material

With a rapidly decreasing amount of resources for construction, wood and bamboo have been suggested as renewable materials for increased use in the future to attain sustainability. Through a literature review, bamboo and wood growth, manufacturing and structural attributes were compared and then scored in a weighted matrix to determine the option that shows the higher rate of sustainability. In regards to the growth phase, which includes water usage, land usage, growth time, bamboo and wood showed similar characteristics overall, with wood scoring 1.11% higher than bamboo. Manufacturing, which captures the extraction and milling processes, is experiencing use of wood at levels four times those of bamboo, as bamboo production has not reached the efficiency of wood within the United States. Structural use proved to display bamboo’s power, as it scored 30% higher than wood. Overall, bamboo received a score 15% greater than that of wood, identifying this fast growing plant as the comparatively more sustainable construction material.

Within recent years, the drive for increased sustainability within large corporations has drastically increased. One critical measure within sustainability is the diversion rate, or the amount of waste diverted from landfills to recycling, repurposing, or reselling. There are a variety of different ways in which a company can improve their diversion rate, such as repurposing paper. A conventional method would be to simply have a recycling bin for collecting all paper, but the concern for large companies then becomes a security issue as confidential papers may not be safe in a traditional recycling bin. Salt River Project (SRP) has tackled this issue by hiring a third-party vendor (TPV) and having all paper placed into designated, secure shredding bins whose content is shredded upon collection and ultimately recycled into new material. However, while this effort is improving their diversion, the question has arisen of how to make the program viable in the long term based on the costs required to sustain it. To tackle this issue, this thesis will focus on creating a methodology and sampling plan to determine the appropriate level of a third-party recycling service required and to guide efficient bin-sizing solutions. This will in turn allow for SRP to understand how much paper waste is being produced and how accurately they are being charged for TPV services.

Lignin is an energy dense polymer that forms the secondary layer within a plants cell wall. Within the cell wall, lignin acts as a matrix material, providing structural integrity to the plant. This polymer is often a byproduct from harvesting cellulose and has traditionally been used in resins, insulation, and adhesives. Recent research has indicated that lignin’s hierarchical structure may offer advantage in dissipating fracture energy while its fibrous composite arrangement prevents crack growth. Because of lignin’s unique chemical characteristics, different formulations and combinations with resins and bioplastics using lignin has started to make way for a new cost-effective and non-polluting alternative for the current petroleum-based plastics used globally. The goal of the following project was to develop a material that could show resilience in replacing the petroleum-based plastic used in small format items whilst also demonstrating high efficacy in biodegradation.
