“…For the commercialization of the liquid fertilizer, maintenance of its quality is also important during preservation. In our previous study [26], liquid fertilizer was produced from fish waste and its quality can be maintained by the addition of 1% lactate for 6 mon without any putrefaction. This was due to a bacteriostatic effect of lactate [27].…”

“…Therefore, an appropriate control of large-scale process is necessary to maintain the quality of the liquid fertilizer. In hydroponic culture, the length of a leaf was found out to be a prominent indicator for growth of red bean or barley [26]. According to this result, hydroponic culture was performed on a red bean seed or barley seed by using 52-hr culture of inoculated FMW.…”

A scaled-up bioconversion of fishmeal wastewater (FMW) into liquid fertilizer was performed five times in a 1 m 3 reactor in order to examine the feasibility of commercialization. The importance of aeration was marked. Analyses indicated that dissolved oxygen (DO) level was closely related to the value of oxidation-reduction potential (ORP) and it was crucial to achieve high-quality liquid fertilizer. When pure oxygen was supplied through four diffusers into the reactor, DO levels and ORP values were maintained over 1.2 mg/L and 0.2 mV, respectively all the time during 52 hr of bioconversion. The pH changed from 6.8 to 5.9. The average removal percentages of chemical oxygen demand (COD Cr ) and total nitrogen (TN) were 75.0% and 71.6%, respectively. Compared to the result acquired in a 5-L reactor, bioconversion of FMW into liquid fertilizer was achieved in a shorter time under the same removal percentages of COD Cr and TN. The 52-hr culture of inoculated FMW was phytotoxic-free and it possessed comparable fertilizing ability to a liquid fertilizer made from the fish waste in hydroponic culture with amino acid contents of 5.93 g/ 100 g sample. From all the above results, transferring labscale data to large-scale production appeared to be successful. As a result, the commercialization of a liquid fertilizer made from FMW was feasible.

“…In otherwords, they are technologies which should be encouraged for wider distribution among other countries." Commonly used innovative waste reduction approaches include source reduction by dematerialization, product reuse, remanufacturing, size reduction and separation, material recycling, composting, hydrolysis, pyrolysis, and incineration [15][16][17][18][19][20]. Innovative waste reduction technologies by dematerialization involve reducing the amount of materials that is used per unit output.…”

Increasing number of innovative waste reduction technologies are continuously being developed across various industrial sectors. Adoption and assimilation of proven waste reduction technologies can lead to significant resource savings, cost reduction, protection of biodiversity, and environmental conservation. However, transfer and adoption of technologies either across industrial sectors or geographical jurisdictions may pose enormous challenges to the adopters. In this study, issues affecting successful adoption and assimilation of waste reduction technologies from developed countries to developing countries and from one industrial sector to another were examined. Potential solution based on empirical study were also proposed. The study involved extensive literature survey and analysis of adoption procedures used by a number of technology adopters observed. It was discovered that the sustainability of waste reduction technology adopted depends on the fitness of the technology to the overall corporate success strategy, its compatibility with the corporate culture, availability of enabling operational infrastructure, sustained socio-political interest, and lifecycle cost of the technology.

A study was conducted to examine the utilization of seafood processing wastes for artificial cultivation of edible mushroom Pleurotus flabellatus in laboratory condition. Utilizing bioconversion technology such as the slow release of nutrients for agricultural based activities like producing mushroom will profitably reduce seafood waste and also enhancing environmental quality. The selected agro-industrial wastes such as coir pith, woodchips and sugarcane bagasse were mixed with cooked fish waste (CFW) in the ratio of 1:1 (500 g : 500 g). The substrates which were not mixed with CFW were treated as control. All the above materials were allowed to decompose partially for about 15 days. The partially composted materials were placed in heat resistant transparent sterilized polyethylene bags. Each sterile bag was then aseptically inoculated with P. flabellatus. The bags were then incubated under ambient temperature and controlled humidity. The maximum biological yield per bed was obtained with sugarcane bagasse control bed 58.05±0.88 g/bed. The lowest yield was observed in the substrate woodchips: CFW (1:1) 24.43±0.30 g / bed. Based on the mass obtained for P. flabellatus, the best substrates were in the ordered of woodchips>coir pith>sugarcane. This could be used to cultivate an edible mushroom while at the same time promoting environmental sustainability and increase soil fertility.
