  • Rice husk revolution

    India produces 200 million tonnes of paddy. One tonne paddy gives 700 kg of rice and 300 kg of rice husk. Rice husk has heating value (calorific value) of 3000 kcal per kg. So it is excellent fuel. So we can burn rice husk and produce steam and generate power from it. For villages 10 KW power plant based on steam engine is quite appropriate which can process 4000 kg. of paddy into unpolished rice ...

  • Innovative method for recovery and valorization of hydroxytyrosol from olive mill wastewaters

    The nutritional properties of olive oil can be attributed to its oleic acid and phenolic compounds content, acting as natural oxidants to prevent human diseases. In particular, hydroxytyrosol has an anti-inflammatory action similar to omega 3 fatty acids from fish oil. The olive oil production was conducted by two extraction procedures: first, a two-phase extraction giving extra-virgin olive ...

  • Production of polyhydroxyalkanoate (PHA) by Ralstonia eutropha JMP 134 with volatile fatty acids from palm oil mill effluent as precursors

    The highest volatile fatty acids (VFAs) concentration from palm oil mill effluent (POME) treated by anaerobic fermentation was achieved for a 1-day process when the main acids used were acetic, propionic and butyric acids. Polyhydroxyalkanoate (PHA) production with VFAs from POME as precursors in the fed-batch mode has advantages over batch mode, both in terms of its productivity and 3HV ...

  • Facts & figures on palm oil

    Introduction Palm oil is a vegetable oil that is a common ingredient in a wide variety of products, ranging from biscuits, bread and noodles to shampoo, candles and deter-gents. It has been estimated that around half of all packaged items found in supermarkets contain it. Palm oil is also used as biofuel. The use of palm oil is expected to continue growing, with an esti-mated doubling of ...

  • Improved recoveries and lower background for the analysis of PAHs in Olive Oil

    Using Supelclean EZ-POP NP and an SLB-5ms GC Column A recent survey implemented by Supelco revealed that 58% of analytical chemists in the food industry find the analysis of compounds in fatty matrices to be highly problematic. Lipid interferences can produce elevated detection limits, contamination of LC and GC systems, and ultimately decrease instrument and column lifetime. ...

  • Chemical and biological properties of a sandy loam soil amended with olive mill waste, solid or liquid form, in vitro

    The profitable use of the large amounts of olive oil mill wastes produced in Greece, as source of soil organic matter, might be probably beneficial to soil microorganism activity. A high rate of organic matter biodegradation was observed in soil samples amended with the liquid form of olive mill wastewater, whereas the vice versa results were obtained with the solid form. When the soil ...

  • Vermicomposting biotechnology: recycling of palm oil mill wastes into valuable products

    Abstract Background Palm oil mill effluent and palm press fiber are problematic wastes generated by the palm oil mill industries in Malaysia. This study has endeavored to assess the possibility of the vermicomposting of residue from the palm oil mills using epigeic earthworms Lumbricus rubellus under laboratory conditions. The study was conducted over 50 days using four combinations in ...

  • Closing the waste loop of palm oil industry in 24 hours

    With Biomax system, it takes only 24 hours to turn palm oil milling wastes into nutrient-rich, pathogen-free organic fertilizer with consistent quality. The technology, developed by the Singapore-based Biomax Technologies, is able to treat palm oil milling wastes such as Empty Fruit Bunch (EFB), fruit fibres, decanter cake, Palm Oil Milling Effluent (POME) sludge, biogas sludge, boiler ash, etc ...

  • Biochemical, morphological, and yield responses of lady's finger plants to varying ratios of palm oil mill waste (decanter cake) application as a bio-

    Background:Decanter cake is produced in large amounts, and its disposal is a major concern in palm-producing countries. Growth morphology and biochemical responses of lady's finger (Abelmoschus esculentus) plants grown on soil amended with different ratios of decanter cake (0%, 10%, 20%, and 30%) were investigated. Results:The soil pH decreased (unamended soil), whereas the electrical ...

  • Oil palm fiber

    Oil palm fiber is produced from empty fruit bunch that are considered as waste after the extraction oil palm fruits. During the manufacturing process of palm fiber , EFB( empty fruit bunches) are shredded, separated, refined and dried. The manufacturing process does not involved chemical process or exposure. Hence the palm fibre is clean ...

  • Fertilizer NPK from human urine and olive oil mill wastewaters

    The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

  • Olive oil Mill Wastewater properties change during infiltration through clay soils

    Olive oil Mill Wastewaters (OMW), are stored in clay basins in the region of Sfax (Tunisia). Field permeability measurements showed that the clay is not completely impermeable and its structure can be modified by the infiltration of OMW. Analysis of chemical composition of soil revealed the presence of phenolic compounds resulting from the percolation of OMW. An infiltration filled with clay and ...

  • Anaerobic degradation of palm oil mill effluent (POME)

    The biodegradation characteristics of palm oil mill effluent (POME) and the related microbial community were studied in both actual sequential anaerobic ponds in Malaysia and enrichment cultures. The significant degradation of the POME was observed in the second pond, in which the temperature was 35–37 °C. In this pond, biodegradation of major long chain fatty acids (LCFA), such as palmitic acid ...

  • Optimised treatment of Palm Oil Mill Effluent

    In this paper, we study experimentally the problem of separating oil from the oil?water emulsion that emulates Palm Oil Mills Effluent (POME). The investigations are focused on the effects of hydrochloric acid (HCl) and treatment conditions, e.g., operating temperature and magnetic stirring, on the separation process. The experiment results reveal that a higher flotation rate of oil is achieved ...

  • Trials about composting of solid wastes from palm oil Mills in Indonesia

    The solid wastes produced in palm oil mills are empty fruit bunch (EFB), mesocarp fibre, shell, and palm kernel cake. On an average the amount of EFB is 0,220 t of 1 t oil palm fruit bunch (Singh, 1994). In Indonesia, there will be about 2.9 million tonnes EFB (dry basis) in 2000 (Lubis et. al. 1994). At the moment, EFB in Indonesian palm oil mills are burnt in incinerators to reduce the mass and ...
