In this presentation, the possibility of converting low-grade vegetable oil or tallow available widely in New Zealand into biodiesel and energy materials will be discussed in an effort to improve the economy of this process. Currently established processes use alkali catalysts such as sodium hydroxide to trans-esterifies any source of lipid using methanol at low temperatures and pressures. However, the manufacturing cost of biodiesel produced remained high, making biodiesel more expensive that petroleum diesel, especially if high grade feedstock is used. Three possible approaches, which may improve the conversion of low grade lipid into biodiesel or useful chemicals, will be discussed in this presentation: development of gas phase reactor  in which the trans esterification reaction takes place only in few seconds rather than many minutes. This is done by spraying the oil or molten tallow into fine droplet against methanol vapor at elevated temperatures, react glycerol, which is a waste product from the biodiesel manufacturing, with the free fatty acid present in the low grade tallow or oil according the esterification reaction shown. The produced monoglycerides can then be easily trans- esterified. This will prevent the harmful saponification reaction, which could consume the catalyst, and use of higher alcohol having higher solubility of the lipid to ease biodiesel production and also to produce energy materials, known as a phase change materials, that can be used to improve energy managements in buildings. In addition the potential of growing and harvesting algae in wastewater for the production of biodiesel will be also discussed.

Food waste represents a major constituent of the municipal solid waste in urban cities while it can be used to produce useful products if well managed. In Hong Kong, the local Government has planned to employ anaerobic digestion to produce biogas from food waste. In consequence, the biogas produced can be converted into different forms of energy use, such as electricity and heat, city gas, and biogas fuel for vehicle use. It is essential to determine the best option for converting food waste based on their environmental performance so as to strive for a sustainable waste management system. In this study, life cycle assessment is conducted to evaluate the life cycle environmental performance of different food waste converting options (i.e., electricity and heat, city gas, and biogas fuel for vehicle use). The LCA is conducted using SimaPro 7.2.4 software with ReCiPe version 1.04 to evaluate both the impact and damage categories. For impact categories, climate change is the key impact category and it is found that biogas fuel as petrol substitute has achieved the best environmental performance compared to other converting options with -103.67 kg CO2e/tonne food waste. If 1,080 tonnes per day of food waste can be converted into biogas fuel as petrol substitute, approximately 2% of greenhouse gas emissions can be reduced in the transport sector in Hong Kong.

A portable and small-scale biomass gasification system has a potential for use in damaged areas  by natural disasters (earthquake, flooding, Tsunami,  etc.)  or  un-electrified rural  areas   in developing  countries. However, the available feedstocks are usually high moisture content ones with different size, shape and properties. Therefore, some pretreatments are essential for efficient gasification of these feedstocks. In this study, woody biomass samples were first carbonized/torrefied by a carbonizer without usage of electricity.  Then the carbonized/torrefied biomass were crushed and molded into briquette shape to be supplied into a fixed bed updraft gasifier. The syngas produced in the gasifier was first cleaned up by physical tar removal processes (the oil scrubbing, the centrifuge misty tar collection and the char bed adsorption) and was then supplied into a  gas  engine with 30kW  electrical output. In  the presentation,  some  detail  results on  the  carbonization/torrefaction process, the briquetting process, the gasification process, the gas clean- up process and the gas engine operation will be presented. Then the mass balance  and  the  energy  balance  of  the  total  system will be analyzed  to show the self-sustainability of this system. This  work was supported by Innovative Science and Technology Initiative for Security, ATLA.

Keynote: Boosting bioenergy by coordinating the activities of chloroplasts and mitochondria

Time : 10:15-10:40

OMICS International Bioenergy 2017 International Conference Keynote Speaker Boon Leong Lim  photo

Boon Leong Lim is an Associate Professor of the School of Biological Sciences at the University of Hong Kong. He obtained a B.Sc from the Chinese University of Hong Kong in Biochemistry (1990) and a Ph.D. degree from the University of Oxford (1994). Dr. Lim has published over 60 original articles and his current research interests focus on carbon flow of plants, plant organelle biology and Omics biology of plants. He has filed a few patents on agrobiotechnology and some of his patents have been successfully licensed to private companies.


Increasing yield has been the ultimate goal of Agrobiotechnology and Biofuel industry for many decades. Current agrobiotech traits mainly rely on preventing yield loss, such as insect-resistance, herbicide resistance and drought resistance. Here we would like to show that manipulation energy outputs of chloroplasts and mitochondria can enhance plant growth and seed yield significantly. Overexpression (OE) of a purple acid phosphatase (AtPAP2) in Arabidopsis results in faster plant growth and higher seed yield (+40-50%). The OE lines contain significant higher ATP and sucrose levels than the wild-type (WT). Subcellular localization studies showed that this phosphatase is anchored on the outer membranes of the two energy generating organelles of plants, chloroplasts and mitochondria. Our data show that AtPAP2 affects the energy output from these two organelles by modulating import of certain nuclear-encoded proteins into chloroplasts and mitochondria, and thus affect their energy harvesting and energy conversion efficiencies, respectively. Based on the data of chlorophyll fluorescence measurement, transmission electron microscopy, 2D Blue Native/SDS-PAGE analyses, enzyme assays, oxygraph measurement, and proteomics analysis, we proposed a model to explain how AtPAP2 enhances sugar and ATP production in leaf cells of Arabidopsis thaliana by simultaneously coordinating the activities of chloroplasts and mitochondria. Homologous sequence of AtPAP2 can be found in the genome of some green algae. Our discovery may open up a new direction for Agrobiotechnology and bioenergy research.
