Abstract. Oil extraction rate (OER) is essential in measuring palm oil mills' performance and competence. One of the attempts to achieving high OER exploring possibility recovering residual from mill effluent (POME). A recent technique called progressive freezing (PF) has been proposed reclaim POME, forming a block solid system. This article focuses on evaluating quality recovered through its p...

Abstract Oil palm dominates global oil production, trade, and consumption. Nigeria is one of the leading producers consumers. A significant challenge industry to reduce environmental impacts (e.g. pollution carbon footprint) integrate a circular economy in operation. This study aims comparatively quantify technologies used by different mills. We applied life cycle assessment case Nigeria. The c...

Since 1974 the Decco-Tiltbelt Division of Penn walt Corporation has been conducting research programs on the experimental fungicide l-[2-(2,4-dichlorophenyl)-2-(2propenyloxy) ethyl]-IH-imidazole (Imazalil) at their Mon rovia, California Research Laboratory. Tests have proven the efficacy of this fungicide against postharvest diseases of citrus. It is especially effective in sporulation and deca...

Palm oil mill effluent (POME) is one of the main agro-industrial wastewaters in Malaysia. Highly polluting POME a serious threat to environment. In recent years, methods used treat are inefficient and complex terms cost or environmental preservation. The object this research propose single reactor system (SRS) obtained from wastewater discharge as promising low-cost treatment high-energy method...

Immobilization of lipase enzyme produced from palm oil mill effluent (POME) by the activated carbon (AC) among the low cost support materials was optimized. The results indicated that immobilization of 94% was achieved by AC as the most suitable support material. A sequential optimization strategy based on a statistical experimental design, including one-factor-at-a-time (OFAT) method was used ...

Abstract The principle of maximum entropy (POME) is employed to derive a new method of parameter estimation for the 3-parameter generalized Pareto (GP) distribution. Monte Carlo simulated data are used to evaluate this method and compare it with the methods of moments (MOM), probability weighted moments (PWM), and maximum likelihood estimation (MLE). The parameter estimates yielded by the POME ...

Ionizing irradiation is used in Florida and Hawaii to disinfest several fruits and sweetpotatoes of fruit flies (Diptera: Tephritidae) or other insects (Hallman 2004a). Importation of fruit irradiated against 11 fruit fly species and the mango seed weevil, Cryptorhynchus mangiferae (F.) (Coleoptera: Curculionidae), has been approved (APHIS 2002). The treatment shows promise for widespread imple...

Poly(3-hydroxybutyrate) [P(3HB)] homopolymer and poly(3-hydroxybutyrate-co-3hydroxyvalerate) [P(3HB-co-3HV)] copolymer was produced by Comamonas sp. EB172 using single and mixture of carbon sources. Poly(3-hydroxyvalerate) P(3HV) incorporation in the copolymer was obtained when propionic and valeric acid was used as precursors. Incorporation of 3HV fractions in the copolymer varied from 45 to 8...

Chemical synthesis of palm oil trimethylolpropane esters was conducted via transesterification of palm oil methyl esters (POME) with trimethylolpropane (TMP). The palm oil TMP esters are potential biodegradable base stock for lubricant production. The influence of the main operating variables, namely, temperatures and pressures, molar ratio of palm methyl esters to TMP, and catalyst amount was ...

There is limited data regarding the specific problems faced by organic fruit growers when dealing with plant protection, particularly at a European Union level, though some general knowledge about pest and disease incidence can be found. Such information crucial to improve efficacy of targeted transfer advisors aiming an increased adoption innovative practices. A survey was thus carried out in ...
