Mitigating ammonia and greenhouse gas emissions from stored cattle slurry using agricultural waste, commercially available products and a chemical acidifier.
(Elsevier, 2021-02-05)
Bovine slurry and its subsequent storage are significant sources of ammonia (NH3) and greenhouse gases (GHGs). Chemical acidification of manures has been shown to significantly reduce these emissions. Waste products, derived ...
Simultaneous adsorption and biodegradation of trichloroethylene occurs in a biochar packed column treating contaminated landfill leachate
(Elsevier, 2021-08-14)
Trichloroethylene (TCE) is a human carcinogen that is commonly found in landfill leachate as a result of anthropogenic activities. Contaminated leachate plumes may be intercepted prior to reaching groundwater and treated ...
An examination of maximum legal application rates of dairy processing and associated STRUBIAS fertilising products in agriculture
(Elsevier, 2021-10-09)
The dairy industry produces vast quantities of dairy processing sludge (DPS), which can be processed further to develop second generation products such as struvite, biochars and ashes (collectively known as STRUBIAS). These ...
Driven cast-in-situ pile capacity: insights from dynamic and static load testing
(Canadian Science Publishing, 2021-02-11)
Driven cast-in-situ (DCIS) piles are classified as large displacement piles. However, the use of an oversized driving
shoe introduces additional complexities influencing shaft resistance mobilisation, over and above those ...
Evaluation of the fertiliser replacement value of phosphorus-saturated filter media
(Elsevier, 2021-01-12)
The use of filter media to adsorb phosphorus (P) from nutrient-rich waters is an effective, simple and low-cost method to recover and reuse P as an inorganic fertiliser replacement. Although it is assumed that the saturated ...
Accounting for research induced environmental impacts using life cycle assessment
(Frontiers Media, 2021-03-18)
Since the 1970's the number of scientific publications with sustainability as a keyword has increased from 1 in 1975 to 13,628 in 2019. Research, like all human endeavors, has impacts on the environment due to the activities ...
Densified wood dowel reinforcement of timber perpendicular to the grain: a pilot study
(Taylor & Francis, 2021-06-07)
An investigation was carried out to examine the potential to utilise densified wood dowels as a reinforcement for timber subjected to compression loading perpendicular to the grain. While timber has a high strength-to-weight ...
Impact of source variability on flexibility for demand response
(Elsevier, 2021-08-05)
This paper assesses the quality of the services provided for demand response by analysing the results of experimental work activating flexible sources in buildings, while evaluating the impacts on occupant comfort and ...
Temperature sensing optimization for home thermostat retrofit
(MDPI, 2021-05-26)
Most existing residential buildings adopt one single-zone thermostat to control the heating
of rooms with different thermal conditions. This solution often provides poor thermal comfort and
inefficient use of energy. The ...
Transfer learning applied to DRL-Based heat pump control to leverage microgrid energy efficiency
(Elsevier, 2021-09-11)
Domestic hot water accounts for approximately 15% of the total residential energy consumption in Europe, and most of this usage happens during specific periods of the day, resulting in undesirable peak loads. The increase ...
