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 ...
Use of rapid small-scale column tests for simultaneous prediction of phosphorus and nitrogen retention in large-scale filters
(Elsevier, 2020-07-01)
Rapid small-scale column tests (RSSCTs) have been previously used to predict the effluent concentration of a single nutrient in large filters with good accuracy. However, in drainage waters originating from heavy textured ...
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 ...
Mineral fertiliser equivalent value of dairy processing sludge and derived biochar using ryegrass (Lolium perenne L.) and spring wheat (Triticum aestivum)
(Elsevier, 2022-08-20)
As supply chains of chemical fertilisers become more precarious, raw or derived bio-based fertilisers (herein referred to as bio-fertilisers) from the dairy processing industry could be good alternatives. However, their ...
Appraisal and ranking of poly-aluminium chloride, ferric chloride and alum for the treatment of dairy soiled water
(Elsevier, 2020-04-29)
Land spreading of dairy soiled water (DSW) may result in pollution of ground and surface waters. Treatment of DSW through sludge-supernatant separation using chemical coagulants is a potential option to reduce the negative ...
Investigating the suitability of synthetic envelopes as an alternative or complement to stone aggregate in clay-textured soils in Ireland
(Elsevier, 2022-12-21)
In Ireland, agricultural landscapes dominated by high rainfall and poorly drained soils have high densities of in-field pipe drains surrounded by stone aggregate envelopes. Unlike other countries, there is limited availability ...
Dairy processing sludge and co-products: a review of present and future re-use pathways in agriculture
(Elsevier, 2021-06-22)
The dairy industry is one of the largest global producers of wastewater and generates huge volumes of dairy processing sludge (DPS). There are two main types of DPS, lime-treated dissolved air floatation sludge and ...
Systematic review of dairy processing sludge and secondary STRUBIAS products used in agriculture
(Frontiers Media, 2021-11-10)
Worldwide dairy processing plants produce high volumes of dairy processing sludge (DPS), which can be converted into secondary derivatives such as struvite, biochar and ash (collectively termed STRUBIAS). All of these ...
