This practice-based paper explores the methods of answering the question: what is our collective body? This article offers a case study of collaborative research and seeks to enact a collective body ...as a means of transgressing and occupying individuated neoliberal spaces of higher education. Understanding the processes through which knowledge is collectively built highlights the in-becoming nature of practice-based research and the enabling forces of this inquiry. The methods enacted access a particular rendering of how we understand ourselves as a collective; we answer the question through doing together. The ways we encounter the collective enable understanding around the shifting boundaries of the individual–collective connection, made palpable by a string. Through playful forms of dissent, such as embodied, remembered, and writing encounters, enable connections with others and inspire a refocusing of our individual practices.
Polylactic acid (PLA) and bioplastics alike have a designed degradability to avoid the environmental buildup that petroplastics have created. Yet, this designed biotic-degradation has typically been ...characterized in ideal conditions. This study seeks to relate the abiotic to the biotic degradation of PLA to accurately represent the degradation pathways bioplastics will encounter, supposing their improper disposal in the environment. Enzymatic hydrolysis was used to study the biodegradation of PLA with varying stages of photoaging. Utilizing a fluorescent tag to follow enzyme hydrolysis, it was determined that increasing the amount of irradiation yielded greater amounts of total enzymatic hydrolysis by proteinase K after 8 h of enzyme incubation. While photoaging of the polymers causes minimal changes in chemistry and increasing amounts of crystallinity, the trends in biotic degradation appear to primarily be driven by photoinduced reduction in molecular weight. The relationship between photoaging and enzyme hydrolysis appears to be independent of enzyme type, though commercial product degradation may be impacted by the presence of additives. Overall, this work reveals the importance of characterizing biodegradation with relevant samples that ultimately can inform optimization of production and disposal.
