Food processing industry including fruit and vegetable processing is the second largest generator of wastes into the environment only after the household sewage. The generation of biodegradable waste increased linearly with the growth and development of food processing industry. A huge amount of waste in the form of liquid and solid is produced in the fruit and vegetable processing industries i...

In recent years, in Korea, recirculating aquaculture technologies for intensive fish culture are increasingly being used to enhance production of a high quality aquacultural products all year around including seawater. In high density aquaculture system, the increase of protein and organic particulates by uneaten feed, feed waste and excreta of fish gives a bad effect in fish growth and environ...

Cleaning up and disposing of approximately 50 years of nuclear waste is the main mission at the U.S. Department of Energy’s Hanford Nuclear Reservation, located in the southeastern part of the state of Washington. A major element of the total cleanup effort involves retrieving, processing, and disposing of radioactive and hazardous waste stored in 177 underground storage tanks. referred to as t...

biological packaging material based on obtained proteins from fish waste, are biopolymers that have the capability of biodegradable film formation. thus, purpose of this research is to study and investigate some of films’ physical features made from trout fish myofibril protein. the film forming solution containing 1.5%, 2% and 2.5%(w/v)myofibril protein isolate of 100ml solution and glycerol a...

Proteolytic and/or lipolytic lactic acid bacteria (LAB) were isolated from visceral wastes of different fresh water fishes. LAB count was found to be highest in case of visceral wastes of Mrigal (5.88 log cfu/g) and lowest in that of tilapia (4.22 log cfu/g). Morphological, biochemical and molecular characterization of the selected LAB isolates were carried out. Two isolates FJ1 (E. faecalis NC...

This paper presents a multi-objective optimization model for the design of a waste management system consisting of customers, transfer stations, landfills and collection vehicles. The developed model aims to simultaneously minimize the total costs, greenhouse gas emissions and the rates of energy consumption. To tackle the multiple objectives in the problem, we utilize an interactive fuzzy prog...

The present study investigated contamination of polybrominated diphenyl ethers (PBDEs) in sediment and fish samples collected from rivers in Guiyu, China where electronic waste (e-waste) is recycled and disposed. PBDE congeners with mono-to hepta-brominated and deca-brominated substitutions were detected using (13)C(12) isotope dilution GC/MS/MS and GC/MS methods, respectively. The total PBDE c...

A medium using fish waste as substrate was designed for production of lipase by Enterococcus faecium MTCC 5695 and Pediococcus acidilactici MTCC 11361. Medium components and culture conditions (fish waste protein hydrolysate (FWPH) concentration, fish waste oil (FWO) concentration, pH, temperature, and fermentation time) which affect lipase production were screened using factorial (5 factors ∗ ...

Frozen shrimp and fish are the second most valuable export items from Bangladesh. Thus, in processing industries, a considerable amount of seafood waste is produced every year. Neglecting leads to serious forms wastage. The purpose this survey-based study was estimate understand existing management practices Potential for waste-based silage production its utilization were also studied. Across i...
