Thermal treatment of human feces is an effective means of managing both volume reduction and pathogen kill. In this work, a detailed combustion profile of fecal solid waste was measured using micro-combustion and bomb calorimetery. Sample sets from multiple locations were obtained from both point of source (toilet – India, United States, South Africa) and pit latrine (Kenya). Results include heat release profiles, volatile, char, and ash mass fractions, and the caloric content of volatiles and char. These data allow for the optimization of current thermal processes and advances technologies where thermal remediation is core to processing fecal solid waste.

The forthcoming international standard for fecal sludge treatment units, ISO/PC 318 requires technologies to exhibit energy neutrality and satisfaction of pathogen threshold values. Research and development efforts at Biomass Controls focus on compliance with this standard. This involves the development of an energy flow analysis and research into the time-temperature relationships required for complete pathogen inactivation. The results of these efforts have yielded that thermal treatment units should be capable of achieving energy neutrality in steady state using only the energy contained in fecal sludge and that pyrolysis/combustion temperatures are adequate for complete pathogen inactivation.

The Bill & Melinda Gates Foundation Reinvent the Toilet (RT) program aims to “bring sustainable sanitation solutions to the 2.5 billion people worldwide who don’t have access.” Duke University and partners have developed a modular, on-site waste processing system that seeks to provide safe and reliable treatment of all inputs that exceed the metrics set by ISO 30500. Currently, sub-systems are being evaluated and re-engineered to reduce complexity, reduce energy reliance, and develop strategies for productization. To further the development of such transformative technologies, field prototypes have transitioned from the laboratory to field testing sites (Ahmedabad and Coimbatore, India and Durban, South Africa).

The digital transformation provides an opportunity to more efficiently monitor and regulate faecal sludge management services. To achieve this, software solutions for data collection and analysis need to be developed. The results of a software development process for a thermal faecal sludge treatment technology are presented. The process is presented in three steps: (1) analysis of raw data collected in a cloud database, (2) development of meaningful Key Performance Indicators for monitoring of compliance to standards, safety, and performance, (3) a simple to comprehend and powerful data visualisation for operators, regulators and manufacturers.

Innovators in the water and sanitation sector are focused on closing the sanitation gap in developing countries. The sanitation sector is challenged to deliver improvements that meet the practices and preferences of all genders. This presentation shares survey research with a set of global research and development (R&D) teams that are in the midst of an innovation drive for leap-frog sanitation treatment and resource recovery technologies. Findings suggest a majority of teams incorporated gender into their work, though the incorporation was generally limited in scope and not deep in understanding gender dynamics. Teams designing elements of a user-interface were more likely to incorporate gender disaggregated elements. Waste-processing technology was often assumed to be gender-neutral, not requiring differentiated thinking on how various genders interact with the novel technologies. This work fills a gap in R&D and technology adoption in how to evaluate and foster a gender lens into R&D activities in the international development water and sanitation sector.

Menstrual hygiene management (MHM) is a neglected topic in the water and sanitation sector, with waste disposal often absent in most MHM programming. This work illustrates that the integration of private and safe disposal mechanisms for menstrual absorbents into sanitation facilities is valued. It brings many co-benefits in health and dignity, and safeguards community environmental health and protects toilet facilities. The integration of MHM, including waste management into WASH investments furthers SDG goals for access, empowerment, dignity and public environmental health.

Human excreta derived fertilisers (HEDF) help replenish soil organic matter and nutrients but barriers exist to their wide-scale use. A case study on the acceptability of HEDF for producing crops for export in Kenya is presented here. Farming certification schemes are unclear on the use of products derived from human excreta on farms. Farmers must abide to these schemes to enter the export market and are therefore unwilling to use HEDF. Analyses on soils treated with HEDF showed no evidence of contamination after HEDF application. An assurance scheme specific to HEDF could help increase trust and acceptance of these fertilisers.

Biomass Controls is developing an existing pyrolysis-based thermal Biogenic Refinery into a Combined Heat and Power (CHP) community-scale, non-sewered sanitation treatment system using a micro-scale organic rankine cycle (ORC) engine. This Faecal Sludge Treatment Unit (FSTU) has proven energy independent operation at steady-state with electrical energy generated by the ORC, from recovered thermal energy, as sufficient to power the electrical requirements of the entire system.
This self-sustaining CHP FSTU was developed for compliance with the energy independence portion of the standard for community-scale resource-oriented sanitation treatment systems, as in-development by the International Standard Organisation Project Committee 318.

Leveraging IoT Technology for Building Smart Sanitation Solutions | Ballroom

The benefits of data capture are clear, as data answers critical questions on user interactions with sanitation products and solutions: how is our equipment being used? When is it being used? Who is using it? What is the condition of our equipment? Is it operating as expected? New and exciting sensor technology is constantly appearing. Sensors for civil engineering, pollution, lighting, medical data, and security to name a few have become universally available. However sensors are only valuable if the data they capture is made available and can produce useful information upon which decisions are made.
