Mycelial paper: A potential resource recovery process?

Industrial wastewater and other trade wastes are often sources of pollution which can cause environmental damage. However, resource recovery approaches have the potential to lead to positive environmental outcomes, profits, and new sources of finite commodities. Information on these waste sources, and the valuable components which may be contained in such waste is increasingly being made available by public, academic and commercial stakeholders (including companies active in meat processing, dairy, brewing, textile and other sectors). Utilising academic and industry literature, this review evaluates several methods of resource recovery (e.g., bioreactors, membrane technologies, and traditional chemical processes) and their advantages and disadvantages in a trade waste setting. This review lays the groundwork for classification of waste and resource recovery technologies, in order to inform process choices, which may lead to wider commercial application of these technologies. Although each waste source and recovery process is unique, membrane bioreactors show promise for a wide range of resource recovery applications. Despite interest, uptake of resource recovery technologies remains low, or not widely championed. For this to change, knowledge needs to increase in several key areas including: availabilities and classification of trade wastes, technology choice processes, and industrial viability.

Fecal Sludge

Background: Little is known about occupational exposures that occur along fecal sludge collection and resource recovery processes. This study characterizes inhaled endotoxin exposure to workers of a municipal scale fecal sludge-to-fuel processes in Kigali, Rwanda. Methods: Forty-two task-based air samples were collected from workers in five tasks along the fecal sludge collection and resource recovery process. Samples were processed for endotoxin using the limulus amebocyte lysate (LAL) test. To account for exposure variability and compare measured concentrations to established exposure limits, we used Monte Carlo modeling methods to construct distributions representing full eight-hour (8-h) exposures to endotoxin across eight exposure scenarios. Results: Geometric mean (GM) endotoxin concentrations in task-based samples ranged from 11–3700 EU/m3 with exposure concentrations increasing as the dryness of the fecal sludge increased through processing. The thermal dryer task had the highest endotoxin concentrations (GM = 3700 EU/m3) and the inlet task had the lowest (GM = 11 EU/m3). The geometric means (GM) of modeled 8-h exposure concentrations were between 6.7–960 EU/m3 and highest for scenarios which included the thermal dryer task in the exposure scenario. Conclusions: Our data suggest the importance of including worker exposure considerations in the design of nascent fecal sludge management processes. The methods used in this study combine workplace sampling with stochastic modeling and are useful for exposure assessment in resource constrained contexts.

Traditional Medical Model

Purpose Person-centered care shifts the focus of treatment away from the traditional medical model and moves toward personal choice and autonomy for people receiving health services. Older adults remain a priority for person-centered care because they are more likely to have complex care needs than younger individuals. Even more specifically, the assessment and treatment of swallowing disorders are often thought of in terms of setting-specific (i.e., acute care, skilled nursing, home health, etc.), but the management of dysphagia in older adults should be considered as a continuum of care from the intensive care unit to the outpatient multidisciplinary clinic. In order to establish a framework for the management of swallowing in older adults, clinicians must work collaboratively with a multidisciplinary team using current evidence to guide clinical practice. Private practitioners must think critically not only about the interplay between the components of the evidence-based practice treatment triad but also about the broader impact of dysphagia on caregivers and families. The physical health and quality of life of both the caregiver and the person receiving care are interdependent. Conclusion Effective treatment includes consideration of not only the patient but also others, as caregivers play an important role in the recovery process of the patient with swallowing disorders.
