Recycling shrimp farming water is a way to address the trend toward a circular economy in Vietnam's coastal regions while also reducing the quantity of effluent that is released into the environment. In order to explore the potential for waste recycling, this study investigates the pond system of a highly intense Littopenaeus vannamei culture area in Ca Mau province.

The impacts of waste on shrimp culture environment are determined through analyzing the results of measuring water quality criteria in the pond, thereby assessing the efficiency of waste removal of the equipment. The measurement results show that water quality parameters reach a value within the threshold if operating a waste suction device once per day. The benefits of waste remover operate are to help save the cost of labor to clean the pond bottom, protect workers' health.

The present study evaluated the use of nonconventional carbon source, de-oiled oil palm kernel meal (Elaeis guineensis), which is a low-cost palm oil industry waste for biofloc production. The effects of de-oiled oil palm kernel meal on water quality, growth and digestive enzyme activity of L. vannamei were studied to assess the viability of this carbon source in biofloc systems.

Biological treatment aims at using plants and animals to reduce nutrients load and particulate matter in shrimp farm discharge. Although extensive literature is available on the different types of shrimp culture practices, its advantages and disadvantages including the impact caused due to enormous application of chemicals such as antibiotics and use of robotics, he information available on the treatment of effluent in general and biological methods in particular are very scarce.

Marine aquaculture is the fastest growing food producing sector with major contribution from carps in terms of volume and shrimp by value. Continuous development of aquaculture demands new alternative technologies to achieve sustainable production with low economic cost. The microbial based systems like biofloc technology (zero water exchange systems) and artificial substrate integrated (periphyton based) in normal culture systems represents the best methods of practice to get healthy shrimp production.

In this study, factors affecting the extraction yield of carotenoids from dried shrimp waste by organic solvents have been studied. The results showed that the solvent ratio hexane: acetone = 3: 1 gave the highest carotenoid yield. At this ratio of solvent’s mixture, the carotenoid yield reached highest at temperature 60 C after 2 hours extraction, which was 44.64 µg/g raw shrimp waste (d.b.) (ratio of solvent to raw material 3/1). Ultrasound or vortexing gave higher extraction yield than in static conditions, which was 1.8- fold to 1.5- fold increase, respectively.

Shrimp head waste has been used as raw materials for production of chitin and protein hydrolysate. In this study, a facile and efficient pressing method was developed to separate the solid and liquid phases from shrimp heads. The different solid/liquid ratios as well as the size of the solid component can be obtained easily by changing the pressing operating parameters. The solid fraction was used to prepare chitin and chitosan. This pressing method can save large amount of water and chemicals in the production of chitin and it can be used in the large-scale.

Carotenoprotein was extracted by a hydrolysis method using both inorganic and organic acids. Shrimp heads were firstly hydrolyzed by adding a 0.2% (w/v) hydrochloric acid solution at room temperature for an hour following by hydrolyzing with a 0.4% (v/w) formic acid solution for another 2 h at the same temperature. The obtained carotenoprotein consisted of high contents of protein (57.8 wt.%) and carotenoids (473.9 ppm). This method is facile and efficient for the extraction of carotenoprotein from other shrimp and crab wastes on a large scale.

Abstract: Shrimp chitin and chitosan with improved characteristics were isolated from black tiger shrimp waste pretreated with 0.04 M Salicylic acid for ten hours. The pretreated shrimp shells could be efficiently demineralized and deproteinized at ambient temperature using 0.680 M HCl and 0.620 M NaOH, respectively. The duration of the treatments was 8 hours, the ash and protein residues in the final chitosan were about 0.48% and 0.51% respectively; the viscosity was 4800 cps; the solubility was up to 98%.

European society and the European economy do not yet exploit the full potential for resource efficiency. Much recyclable waste is either exported or sent to landfill. A lack of long-term frameworks holds back planning and investment, most obviously on a climate and energy framework beyond 2020, but also on long term sustainable use of key resources such as air, soil, energy, water, fish and biomass. At the same time, such frameworks can help to galvanise the innovation needed to exploit the potential of the transition to a low-carbon economy in areas like transport, energy and agriculture....

Much attention has increasingly been paid on safety, health and environmental issues, not only in industry but also in the university. Small scale experiments are safer in lowering the risk of chemical contact, more environmentally friendly, produce less waste and gain many other benefits. Although several universities are familiar with small scale chemistry and some universities have operated small scale chemistry laboratories successfully, several other universities have not yet adopted these practices, particularly for organic chemistry laboratory.
