Wind, solar, biomass and hydroelectric is having an impact on your life and could have an even bigger impact in the future. Renewable energy, in the most basic terms, is precisely what it sounds like. It’s power that comes from sources that regenerate, unlike fossil fuels, which only exist in a limited amount.
It will be a major achievement to use waste materials from forestry or paper-pulp industry to produce something which will certainly be a part of the transformation of the marine sector a more sustainable operation.
The Port of Frederikshavn, in Denmark, and Steeper Energy, a Danish specialist energy project and technology development company , along with Aalborg University has entered into a partnership to establish the world’s first biomass-based plant to produce a sustainable marine fuel. The plant will produce sulphur-free fully renewable fuel for the several thousand vessels passing through the port annually. A new zero-tolerance law on sulphur content as well as the general acceptance that every part of society must do its part for climate change are the keys for success, according to the consortium.

we can get a significant amount of energy from land which is currently not being used, for minimal input and without disrupting the local wildlife too much or diverting land currently used for food.
Bioenergy receives a lot of attention as a fossil-fuel alternative. In principle, it’s a renewable resource, as well as being approximately carbon neutral (it neither adds nor removes carbon dioxide from the atmosphere, though this depends on the crop). Some popular types of bioenergy are ethanol derived from corn, sugar cane, switch grass, palm oil, as well as fast-growing trees like poplar and willow. These latter two are generally not made into liquid energy (i.e. they cannot be used to power automobiles), but in Europe they are gaining popularity in homes and industry when the wood is chipped and pressed into energy-dense pellets.
Bioenergy is not without its problems, however. Ethanol derived from corn diverts a food product into the energy sector, raising food prices. In the tropics, conversion of native forests to bioenergy plantations for palm oil is a significant driver for deforestation as well as indirect carbon…

The “green charcoal” is one innovation from the existing materials that we have, now converted to produced energy essential for human’s everyday living. Charcoal doesn’t have to be black, it is also “green”, thus it is sustainable.
For sustainable development, we can make charcoal “green”!
The General Systems Theory influences us that elements on earth from the simplest to the most complex one are interconnected. We are all part of a system-the environment. Barry Commoner, a scientist, politician and a publisher introduced the four laws of ecology; these say that everything is connected with everything else, everything must go somewhere, nature knows best there no such thing as a free lunch. These would only mean that our waste either biodegradable, non-biodegradable and or recyclable must go somewhere, sadly most of the time it goes back to our own backyards as we neglect the aspect of waste management and environmental protection.
Embracing these ideas we became aware of the emerging societal problems such as the improper waste management and sound recycling practices.
Moreover, environmental demise, poor waste management and lack of livelihood are, for years, been tormenting the…

There are 30,000 large farms in Pakistan employing more than 50 cattle and 18000 farms rearing 200 cattle per farm on the average. Large Farms and cattle owners can produce electricity for others and sell it to the grid. A farm having 1000 cattle can generate 0.5 MW of electricity and a farm of 2000 cattle can generate 1 MW. One can reasonably assume that 1000 such farms can be marshaled to provide atleast 1000 MW, against a total potential of 3800 MW.
Table: Biogas Potential in Pakistan
No of Livestock=56.9 Million
Live stock Biomass generation=1 Mn Tons/day
Number of Large Dairy Farms=30,000 (avg 200 Cattles)
MSW =55000 tons/day
Crop residue= 225000 tons/day
Annual Biogas (Bio-methane) potential=1.6 TCF/yr
Pakistan Ngas Production=1.4 TCF/yr
Existing Short Fall= 1 TCF/yr
CNG consumption=0.164 TCF/yr
LNG projects =0.146 TCF/yr (25 Billion USD imports)

The work involved detailed techno-economic modelling of the processes to convert three feedstocks – sucrose from sugar cane; microalgae; and oily seeds from a tree called Pongamia – to produce a minimum selling price for aviation biofuel. The results showed that using current proven technologies, the biofuels would be economically competitive with crude oil at a price per barrel of $301 (sugarcane), $374 (Pongamia seeds) and $1,343 (microalgae).
Ground-breaking Australian research on the viability of aviation biofuels was released last Friday, at the culmination of almost three years of work by The University of Queensland, James Cook University, The Boeing Company, Virgin Australia, Mackay Sugar and IOR Energy.
The results of the unique study as part of the Queensland Sustainable Aviation Fuel Initiative have been published in the international journal Biofuels, Bioproducts and Biorefining and were presented at the Boeing-hosted Aero Environment Summit in Sydney.
Researchers at the Australian Institute for Bioengineering and Nanotechnology, based at The University of Queensland, looked at the engineering and associated financial viability of biofuel production.

The scramble to meet that 2020 target is creating a new sort of energy business. In the past, electricity from wood was a small-scale waste-recycling operation: Scandinavian pulp and paper mills would have a power station nearby which burned branches and sawdust. Later came co-firing, a marginal change.
Which source of renewable energy is most important to the European Union? Solar power, perhaps? (Europe has three-quarters of the world’s total installed capacity of solar photovoltaic energy.) Or wind? (Germany trebled its wind-power capacity in the past decade.) The answer is neither. By far the largest so-called renewable fuel used in Europe is wood.
In its various forms, from sticks to pellets to sawdust, wood (or to use its fashionable name, biomass) accounts for about half of Europe’s renewable-energy consumption. In some countries, such as Poland and Finland, wood meets more than 80% of renewable-energy demand. Even in Germany, home of the Energiewende (energy transformation) which has poured huge subsidies into wind and solar power, 38% of non-fossil fuel consumption comes from the stuff. After years in which European governments have boasted about their high-tech, low-carbon energy revolution, the main beneficiary seems to be the favoured fuel of pre-industrial…

Options for carbon dioxide removal from the atmosphere include afforestation and chemical approaches like direct air capture of CO2 from the atmosphere or reactions of CO2 with minerals to form carbonates. But the use of biomass for energy generation combined with carbon capture and storage is less costly than chemical options, as long as sufficient biomass feedstock is available, the scientists point out.
Directly removing CO2 from the air has the potential to alter the costs of climate change mitigation. It could allow prolonging greenhouse-gas emissions from sectors like transport that are difficult, thus expensive, to turn away from using fossil fuels. And it may help to constrain the financial burden on future generations, a study now published by the Potsdam Institute for Climate Impact Research (PIK) shows. It focuses on the use of biomass for energy generation, combined with carbon capture and storage (CCS). According to the analysis, carbon dioxide removal could be used under certain requirements to alleviate the most costly components of mitigation, but it would not replace the bulk of actual emissions reductions.
“Carbon dioxide removal from the atmosphere allows to separate emissions control from the time and location of the actual emissions. This flexibility can be important for climate protection,” says lead-author Elmar Kriegler. “You don’t have…

The basic premise of biofuels is that they emit less carbon than traditional fossil fuels. When biofuels are burnt, the gases are less toxic than fossil fuels, the handling and storage is safer, and there is a carbon sequestration credit that occurs when growing crops for the use of biofuels
We all know that driving our cars around town creates a lot of GHG emissions that are not helping the global warming crisis. We know that burning fossil fuels for transport energy contributes to pollution and climate change. But does buying ethanol or biodiesel to fuel our cars actually mitigate any of the carbon emissions? Or is this simply another way for fuel producers to scam extra dollars from the concerned citizen’s wallet?
As with all of the topics we will discuss on this website, there is no easy answer as to what is the most environmentally friendly option for fuelling our energy-intensive world. Certainly our transport system is fossil fuel intensive, and searching for new ways to reduce carbon emissions produced by this large system is a start to creating a world that is sustainable (whatever that means). But as the environmental blogger Damian Carrington states; “there are good…

Researching the use of biomass in energy production I have found a lot of contention and passionate views on the sustainability of this energy source, particularly where large power stations including the likes of Drax are in the process of switching a significant proportion of their fuel to biomass. As always the situation is a lot more complex than it first appears…
Before we launch into the debate lets first take a look at what ‘biomass fuel’ encompasses and what makes it ‘renewable’
Biomass can be extracted from a variety of sources including crop residues (straw etc.), woody biomass (sawdust etc.), urban waste (untreated wood and paper), forest residues, and short rotation (re-planted or coppiced forest). Some biomass can be directly burned to produce energy; some can be converted into another energy product like biofuel and some can be anaerobically digested to produce methane, which can then be burned to…

Furthermore, the water productive strategy that Bamboo makes use of to develop and its ability to regenerate for biomass fuel an average of 25 several years ensures that management expenses are drastically lower producing a better opportunity for return.
Bamboo not only produces a very clear investment decision chance for people that are searching for high yielding environmentally helpful potential customers but also produces a cleaner area to dwell and a much better top quality of daily life for the earth as complete.
“Biomass” has turn out to be something of a buzzword in latest years but what precisely does it suggest? It means woody components or agricultural waste, (this kind of as rice hulls, sugar cane, or corn stalks), as properly as animal squander. These can be employed as fuels to create bioenergy. Biomass fuels are at the moment next only to water as a supply of renewable power…

Current commercial processes for ethanol use sugar cane or Corn kernel which is a kind of starchy biomass. There are two major problems with these popular processes: One is that it competes with food crops which has led to controversial Food versus Fuel debate. Secondly, the cost of production is not competitive vis-a- vis gasoline. These are the reasons for shifting of attention to Cellulosic ethanol.
Challenges with Cellulose processing:
Breaking down plant biomass(cellulosic) is no easy task. Nature has taken millions of years to evolve to make them hard and recalcitrant. This means they have tremendous resistance to natural forces like attacks from bacteria, fungi, insects, extreme weather etc. Therefore breaking cellulose to fermentable sugars is the primary challenge for the researchers in this area. In any bio process to make ethanol, one has to make easily fermentable sugars as the critical step. Cellulosic biomass also contains sugars but…
