This work presents a liquid disposal monitoring originated from uranium enrichment process at Aramar Experimental Center from 1990 to 1998. Assessment of uranium, fluorides, ammoniacal nitrogen, chemical oxygen demand, and pH measurements were made in water samples and compared with results achieved in other countries, as North America and India. The liquid disposal evaluation, generated by uranium enrichment process, showed low levels, considering most parameters established by Federal and State Legislation, aiming environmental pollution control. However, uranium levels were above the limits established by Conselho Nacional do Meio Ambiente, Environment Protection Agency and mainly by the World Health Organization.

The materials removed in the oil separation units of wastewater treatment plants can be referred to as fat, oil and grease (FOG) waste. FOG waste accumulation in treatment plants can cause clogging of pipes, production of excessive scums and foams, and negatively affect air/liquid oxygen transfer. While conventional disposal routes of this material can be limited by its water and organic content, FOG can represent a source of bio-energy other than bio-diesel production.

Municipal solid waste incineration fly ash (MSWIFA) is considered a hazardous solid waste, traditionally disposed by solidified landfill methods. However, solidified landfills present challenges with leaching heavy metals, polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs). To address this issue, this study examined two pretreatment methods for MSWIFA: sintering at 850℃ for 30 min and washing with three water baths (20 min each) at a 3:1 liquid-solid ratio.

Within the context of the circular economy, the transformation of agri-food waste or by-products into valuable products is essential to promoting a transition towards more sustainable and efficient utilisation of resources. Whey is a very abundant by-product of dairy manufacturing. Apart from partial reutilisation in animal feed or some food supplements, the sustainable management and disposal of whey still represent significant environmental challenges.

Outbreaks of infectious diseases involving depopulation of animals require on-farm practices to stage carcasses when final disposal methods are unavailable. The current study assessed various materials and techniques for containing carcasses to minimize leachate and biological substances. The tested materials included tarps, soil, corn stover (CS), and lime, while the methods involved covers, chemical additives, barriers, and containment.

Background: Amoxicillin suspension is frequently prescribed to children; we hypothesized that prescribing convention system constraints lead to unusual dosing regimens and unnecessary waste of the drug.
Objective: Identify antibiotic dispensing practices by community pharmacists and/or technicians to understand opportunities to decrease wasted amoxicillin liquid and optimize prescribing convention of liquid amoxicillin to children.
Methods: Pilot online survey of Atlanta area and National Community Pharmacists Association pharmacists or pharmacy technicians that self-reported dispensing amoxicillin suspension.
