Sustainability's Inconvenient Discourse, Christine Gilbert
Sustainability's Inconvenient Discourse, Christine Gilbert
Honors College
“Sustainability” has been used to indicate certain values, market a way of life, and possesses a prominent role in a number of different disciplines, yet a commonly accepted definition doesn’t seem to exist. This thesis does not aim in any sense to define this elusive term, rather it examines the themes that inform discussions of sustainability. A number of particular thematic elements are used consistently across almost all of the discourses of sustainability: generational time frames, renewable resources, as well as the relationship between sustainability and economic development. Each unique discourse handles these themes in a specific way. What’s valuable …
Biodegradation And Feasibility Of Three Pleurotus Species On Cigarette Filters, Raymond Updyke
Biodegradation And Feasibility Of Three Pleurotus Species On Cigarette Filters, Raymond Updyke
Honors College
This study was designed to evaluate the biodegradation and feasibility of growing three oyster mushroom species - Pleurotus ostreatus, Pleurotus citrinopileatus, and Pleurotus djamor - on three different cigarette filter waste substrates: intact cigarette filters, blended cigarette filters, and smoked, intact cigarette filters. Cigarette filters are a common waste and are made primarily of cellulose acetate. Oyster mushrooms (Pleurotus spp.) have been shown to degrade synthetic polymers similar to cellulose acetate. In the experiment, the substrates were inoculated with mushroom spawn and placed in a growth chamber maintained at 24° C. After a six-week period, mycelium …
