Anchovies are among the largest fish catch worldwide. The anchovy fillet industry generates a huge amount of biowaste (e.g., heads, bones, tails) that can be used for extraction several potentially valuable bioproducts including omega-3 lipids. Following valued oil rich in omega-3, vitamin D3 and zeaxanthin from leftovers using biobased limonene fully circular process, solid residue (anchovy sl...

Several resource recovery projects financed in the last 5 years incorporate preprocessing systems for fuel preparation and materials recovery prior to combus­ tion. These projects represent a return to a system of resource recovery which experienced many technical problems in several projects built in the late 1970s and early 1980s. The purpose of this paper is to review the history of solid wa...

Aquaponics is the science of integrating intensive fish aquaculture with plant production in recirculating water systems. Although ion waste production by f ish cannot satisfy all plant requirements, less is known about the relationship between total feed provided for f ish and the production of milliequivalents (mEq) of different macronutrients for plants, especially for nutrient flow hydropon...

Biodiesel is a non-petroleum fuel designed to run in a diesel engine. It can be made from a variety of different feedstocks, including virgin vegetable oil, waste cooking oil, and animal fats. The aim of this research was to compare and contrast biodiesel made from fish oil to other more traditional sources. In this paper I examined traditional biodiesel feedstocks available in coastal Alaska. ...

AquaFuture operates a 1.8 million gallon recirculating aquaculture facility capable of filtering the waste products from over three quarters of a million fish that are fed over one million pounds of feed per year. This paper describes a compact system for effluent treatment and residuals management that has proven effective at maintaining water quality within compliance limitations. Solids are ...

Introduction: In order to achieve sustainable development in mining, waste management is an essential requirement. The current study aimed to examine industrial solid waste produced in Golgohar Mining and Industrial Company, which is a well-known iron ore extraction and processing complex. Materials and Methods: This cross-sectional study was conducted in two phases from March, 2016 through Ma...

The acute fish test is an animal test whose ecotoxicological relevance is worthy of discussion. The primary aim of protection in ecotoxicology is the population and not the individual. Furthermore the concentration of pollutants in the environment is normally not in the lethal range. Therefore the acute fish test covers solely the situation after chemical spills. Nevertheless, acute fish toxici...
