Sustainability is becoming the norm

Was watching Bloomberg TV this morning and saw Hybrid and Electric Cars being showcased inthe recent North American AutoShow. Sustainable technology is becoming embedded in all cars nowadays. The idea of getting more mileage out of an electric car is no longer a fantasy, we'll be looking at 50 to 60 miles to the gallon by 2020. In order to be more competitive, more car manufacturers are adopting "green" features into their mass market vehicles. Its a similar situation for air and rail industry, the Airbus A380 and Boeing 787 are more fuel efficient per passenger than a Toyota Prius. The modern train is 10 times more fuel efficient  of the Prius, travelling at higher speeds comfortably. The transportation industry is undergoing a change (positive) to develop more fuel efficient modes of transport.

Germany is heading most countries in developing electricity from renewable energy sources, a whopping 35% by 2020. China is increasingly worried about their air pollution situation, hence they have increased their renewable energy target this year to 49GW. Just a few months ago, China announced they are cooperating with Germany on energy policy, industrial collaboration and city wide renewable systems.  

Other industries are also integrating energy and emissions efficiency into their day-to-day operation with reduced cost, enhanced innovation and competitive advantage. In the last decade or so, industrial energy efficiency improvements have globally outpaced those of transportation, utilities and buildings. It is about time, all industry sectors ask the big Sustainability question not only within their corporate structure but also with their customers, suppliers, delivery chains and competitors. It is time to adopt green energy into their baseline design, manufacturing and delivery of products. 

Failure is not an option. Any company that falls behind will inevitably lose the edge and competitiveness against others who do. Germany is one such country to look up to, their green technology sector is going to be 15% of GDP, employing 4 million people by the year 2020. I urge more countries to have an aggressive policy to push the industry towards adopting sustainable technologies until it becomes the norm.

Bioenergy and Biomass Utilisation


Attended a workshop recently on Bioenergy and Biomass Utilisation organised by ICES in collaboration with A*Star Singapore. I'll try and summarise their research outputs here. ICES has been exploring 2nd Generation Biofuels, i.e. derived from non-food crops. I drew up a diagram to better explain things below:




Current research and Development team in ICES have made some fascinating discoveries However i think they have some way to go in order to commercialise these technologies.
  1. In the generation of biofuels via biological process: A single species of Clostridium has been identified as highest yielding strain capable of producing butanol at 29% yield.
  2. Membrane based pervaporation was successfully demonstrated to yield 99.5% alcohol from fermentation broth. This membrane technology is currently being explored for commercialisation.
  3. Novel biocatalysts (enzymes from fungal strains) for biomass hydrolysis and sugar fermentation were identified and tested with Oil palm empty fruit bunch. Results show 84% conversion rate.
I believe there is a great potential to convert biomass from Palm-Oil kernel into biofuels. We are not exploring these options right now because it is too expensive a process for its conversion. That is simply the reason, it is not economical although it is the right thing to do instead of their current practice of dumping underground or burning it off.
