33 Foot Whale Dies From Eating Rubbish

garbage-oceanThis is a true and very sad rubbish clearance story. While this particular incident is certainly a case of “a picture is worth a thousand words” (or more!), we hope that our words give ammunition to those who are working toward positive change to keep our waste removal out of our oceans.

A Gruesome Ghastly Sight

Usually, the sight of a majestic sperm whale is such a magical moment, most people try to freeze frame the image in their mind. In fact, many people stop breathing momentarily they are so excited to see such a magnificent creature! However, this was not the reaction people had on February 27 when a thirty-three foot, totally emaciated, sperm whale washed up dead on Cabo de Palos Beach in southwestern Spain. It was not at all a wondrous sight… it was a gruesome ghastly sight… one of those images that people would prefer to block from their mind but can’t no matter how hard they try!

The sight of this gigantic creature, lying there dead, the life sucked out of it from eating our rubbish clearance, is heartbreaking to everyone who has viewed the scene either in person or via picture. It sent shock waves across the environmental community. Many shared images of the ghostly dead sperm whale on social media. All who saw it seemed utterly horrified, many vowing to do something about it. The mantra seemed to be “Shame on us for allowing this to happen!”

The deceased sperm whale, a juvenile male, weighed in at 6.5 metric tonnes (14,330 pounds, 5900 kilograms). While this may seem massive to a human weighting a mere 175 pounds, it is about seven times less than what male sperm whales usually weigh. He weighed so much less than a juvenile male sperm whale is supposed to weigh, the idiomatic expression, “he was skin and bones,” would not even begin to cover his physical state. It was quite obvious from the pictures that he literally starved to death.

Cause of such a grueling death

Experts at the El Valle Wildlife Recovery Centre  determined that his stomach and intestines were filled with twenty-nine kilograms (sixty-four pounds) of garbage! These included discarded cans, netting, ropes, and plastic bags. With all this rubbish clearance compacting his digestive system, he could not digest real food and he starved to death. In addition, he had a severe stomach infection, most likely because one of the rubbish clearance items he swallowed ripped a tear in his stomach lining.

The pain and torture this young sperm whale must have endured before he finally died and washed ashore to shame humanity must have been extensive. How unjust it is to this creature to not only die but actually die in a way that was very likely slow and tremendously painful.

What do we as humans owe his species for the sin of his death? Should his death be the impetus to do more to rid our oceans of rubbish removal? Should we plaster this image of this whales lifeless emaciated body on anti-litter posters even though it makes us feel awkward and ashamed to see it?

Sperm Whale – A Magnificent Creature

Sperm whales have been forever immortalized in the great novel, Moby Dick, so they will live for eternity on in the human psyche even if they go extinct. However, unlike the dinosaurs that roamed our planet before our time, and went extinct long before we made our great migration out of Africa into the fertile crescent, sperm whales have shared our planet for all of human history.

Many members of our species have come eye to eye with this beast and we must answer for our crimes of littering that has been proven to be the direct cause of this whales death, and in fact, threatens his entire species.

The International Union for Conservation of Nature (IUCN) classifies the conservation status of sperm whales as “vulnerable” which is only one small step away from becoming endangered — and some experts actually argue that sperm whales are already endangered. While it is impossible to do an accurate census of sperm whales, scientists estimate there about 200,000 of these whales left. Keep in mind, there used to be many millions of them in our oceans but they were a favorite of whaling expeditions who hunted them for their valuable blubber, meat, and even their bones.

Sperm whales are now protected under international law so most countries no longer hunt them. However, the Japanese still have a taste for sperm whale and several are harvested for supposed “scientific research” every year. The whale meat from these scientific specimens does get sold in Japanese markets. However, even given this loophole in the law that protects sperm whales, the direct human harvesting of sperm whales pales in comparison to how threatening our rubbish clearance is to the endurance of this species.

Time for Introspection

The sperm whale that washed up dead on Cabo de Palos Beach is only one of many who have died due to eating rubbish clearance. Plastic bags are the biggest culprit but all rubbish in our oceans poses a dire threat to sperm whales and other marine mammals. What we do about our rubbish clearance problem over the next few decades will likely determine the fate of this entire species and many other marine mammals.

The stomach and intestines of sperm whale was filled with 29 kg of garbage

It is important to note how intelligent sperm whales are though to be. Sperm whales have the biggest brains in the animal kingdom, weighing in at five times that of the human brain, with an imposing volume of eight thousand cubic centimeters! They’re also known to express obvious emotions. What would they say to use if we could somehow crack the sperm whale language code? Would they beg us to remove our rubbish from their habitat? Would they appeal to our better angels?

Identifying the Enemies

Sperm whales eat mostly “garden variety” squid, less than a foot in length, but in an ironic twist, their worst enemy is thought to be the giant squid. These colossal squid are usually between ten to thirteen metres (33 to 43 feet). Serrated sucker scars from these ginormous squid are often found on sperm whale bodies. While sperm whales may eat these giant squid, they put up a good fight at minimum and may even be able to kill, or at least harm significantly, a sperm whale at times.

However, the rubbish clearance that we as humans fill our oceans with cause more damage to sperm whales than all the giant squid in the world. We must face the hard reality that our rubbish clearance is directly responsible for the death of sperm whales, and many other marine mammals, and many other animal species for that matter. We must own up to that fact and start seriously working toward finding solutions.

4 Amazing Benefits of Using Natural Gas for Your Home

Homeowners have a variety of energy sources to choose from to power their homes. Each kind offers its own set of benefits and disadvantages. When you are wanting to be more eco-friendly with your energy consumption, there are many benefits of considering natural gas as your go-to energy source.

Uses Of Natural Gas

Natural gas is non-toxic, colorless, odorless and the lowest-carbon hydrocarbon. It can be used for heating and cooking purposes in both residential and commercial settings. It can also be used to fuel power stations to create electricity for use in businesses and homes.

Natural gas can also be found in many industrial processes to create goods and materials from clothing to glass. Plastics and paints are some important products that have natural gas as a crucial ingredient. The uses of natural gas are many and diverse.

Benefits of Natural Gas

Below are some of the top benefits of natural gas to understand.

1. Affordability

In most areas, natural gas is much more affordable than electricity for heating your house and your water. For the same heating tasks, natural gas can cost almost half as much as oil or coal when used as the energy source. Natural gas is a deregulated utility. This means that consumers have fewer restrictions and are able to have control over how much they pay for the gas. Affordable natural gas prices mean a lot of savings throughout the year for homeowners.

2. Eco-Friendly

Natural gas is not as eco-friendly as renewable energy sources like wind and solar. However, it is the cleanest form of fossil fuel available. When compared to coal, natural gas releases almost a third less carbon dioxide and half as less than oil when it is burned. Compared to other fuels, it also lets off little to no sulfur.

3. Dependability

Using natural gas as your energy source is more reliable and dependable for your energy needs. When a big storm hits your area and the power goes out, you will not be able to depend on any appliance that runs off of electricity. For some homeowners, this means no lights, air conditioning, heating or hot water until the power is restored. When you run your appliances using natural gas, you can still operate them when your power is out.

When you have water heaters and other important home appliances operating using natural gas, the gas is often fed to your home in underground pipelines. This allows your energy source to be safe and well-protected from extreme weather conditions such as heavy storms. If you lose electricity, you will not lose all of your comforts while waiting for the power company to fix the issues.

4. Domestic Energy Source

Much emphasis is put on finding energy sources locally instead of having to depend on foreign oils. In addition to being more abundant and economical, relying more on local energy sources is great for the economy and creates more jobs and revenue.

Learn More About Using Natural Gas In Your Area

If you are looking to turn your home into an eco-friendly environment, turning to natural gas can be a great place to start. Natural gas providers offer plans and pricing options that can be suitable for all homeowners and budgets. Allowing most or all of your appliances to receive energy derived from natural gas can bring you many rewards as a homeowner and someone who cares about their impact on the environment.

This alternative energy source over oil and coal will be good for the global community for generations to come. The use of natural gas is on the rise and will become more competitive as consumers and energy providers look to reduce the impact on air pollution and the environment.

Green Ways to Travel the Globe

According to a recent report, 87% of travelers want to travel more sustainably, but only 39% say that they accomplish the task on most or all occasions. Well, in a world that often focuses so heavily on comfort and convenience, it’s understandable. Many cultures and individuals are certainly making great efforts to lead eco-friendly lives, but many are still left wondering how to make those changes. Read on to explore a wide array of green ways to travel the globe.

Where You Go

Carefully choose your destination. Shorter distances without air travel are ideal, but obviously, that’s not always possible. So, if you’re planning to travel a little further, look into visiting destinations that value sustainability as well. It will be easier if the surrounding culture has the same eco-goals.

Places like Amsterdam are great because they do not rely heavily on vehicular transportation. They stick to bikes and their own two feet most of the time which makes a huge difference. Additionally, make sure that you’re not visiting a destination that is already overwhelmed with tourists and travelers to the point of causing harm. You don’t want to be a part of the problem.

How You Get There

It’s no secret that air travel is a unideal form of transportation right now, but since it is often unavoidable, there are a few small things that can help. First, do your research and choose the most fuel-efficient airline. When you do, book a non-stop, flight and sit economy.

A significant portion of a flight’s emissions is during take-off and landing, and business select or first class is responsible for three times more emissions than economy seating. And in preparation, pack lightly because an aircraft burns more fuel when it is carrying a heavier weight.

But, if you can avoid flying, go for a relaxing train ride. Traveling by train is widely popular in places like Europe and in the United States, you can make it the highlight of your journey.  If you need to rent a car, you can check eco friendly car rental is before you book.

Where You Stay

Look for accommodations that prioritize sustainability. Do your research and look for places that have certifications from a third party, like the Global Sustainable Tourism Council or the Rainforest Alliance. It doesn’t mean that you won’t have the amenities that you may want or need, it just means that they abide by a particular set of global standards that aim for a more “green” operation.

Parting Shot

Even if you aren’t able to choose the ideal location, avoid air travel, or stay at a certifiably eco-friendly hotel, don’t worry. There is still plenty that you can do to lighten the load. Support the local economy, bring a reusable water bottle, take shorter showers and go for ecotourism. Just do the best that you can, and you’ll be on the right track.

Analysis of Agro Biomass Projects

The current use of agro biomass for energy generation is low and more efficient use would release significant amounts of agro biomass resources for other energy use. Usually, efficiency improvements are neglected because of the non-existence of grid connections with agro-industries.

Electricity generated from biomass is more costly to produce than fossil fuel and hydroelectric power for two reasons. First, biomass fuels are expensive. The cost of producing biomass fuel is dependent on the type of biomass, the amount of processing necessary to convert it to an efficient fuel, distance to the energy conversion plant, and supply and demand for fuels in the market place. Biomass fuel is low-density and non-homogeneous and has a small unit size.

Consequently, biomass fuel is costly to collect, process, and transport to facilities.  Second, biomass-to-energy facilities are much smaller than conventional fossil fuel-based power plants and therefore cannot produce electricity as cost-effectively as the fossil fuel-based plants.

Agro biomass is costly to collect, process, and transport to facilities.

The biomass-to-energy facilities are smaller because of the limited amount of fuel that can be stored at a single facility. With higher fuel costs and lower economic efficiencies, solid-fuel energy is not economically competitive in a deregulated energy market that gives zero value or compensation for the non-electric benefits generated by the biomass-to-energy industry.

Biomass availability for fuel usage is estimated as the total amount of plant residue remaining after harvest, minus the amount of plant material that must be left on the field for maintaining sufficient levels of organic matter in the soil and for preventing soil erosion. While there are no generally agreed-upon standards for maximum removal rates, a portion of the biomass material may be removed without severely reducing soil productivity.

Technically, biomass removal rates of up to 60 to 70 percent are achievable, but in practice, current residue collection techniques generally result in relatively low recovery rates in developing countries. The low biomass recovery rate is the result of a combination of factors, including collection equipment limitations, economics, and conservation requirements. Modern agricultural equipment can allow for the joint collection of grain and residues, increased collection rates to up to 60 percent, and may help reduce concerns about soil compaction.

Different Types of Thermocouples

Thermocouples are sensors used to measure temperatures. These devices consist of different metals to form two wire legs forming a junction. Manufacturers weld together these two wire legs to make sure the connection is stable. Thermocouple junctions are used to check for changes in temperatures. There are different types of thermocouples available in the market, and these models have distinct characteristics and features.

The Types of Thermocouples

The manufacturing of a thermocouple requires producers to classify units with distinct color codes. Manufacturers classify these codes in either ANSI/ASTM E230 OR IEC60584. The thermocouples, their calibrations, and their color designations (in ANSI/ASTM E320) are:

  • Type K: Yellow (+) / Red (-)
  • Type T: Blue (+) / Red (-)
  • Type N: Orange (+) / Red (-)
  • Type S: Black (+) / Red (-)
  • Type C: N/A
  • Type J: White (+) / Red (-)
  • Type E: Purple (+) / Red (-)
  • Type R: Black (+) / Red (-)
  • Type B: Black (+) / Red (-)

Conversely, here are the thermocouples once more and their calibrations, but with their IEC 60584 color designations:

  • Type K: Green (+) / White (-)
  • Type T: Brown (+) / White (-)
  • Type N: Rose (+) / White (-)
  • Type S: Orange (+) / White (-)
  • Type C: N/A
  • Type J: Black (+) / White (-)
  • Type E: Purple (+) / White (-)
  • Type R: Orange (+) / White (-)
  • Type B: Orange (+) / White (-)

Thermocouple Temperature Range

Aside from the color codes, thermocouple types have specific melting points and continuous maximum temperatures. For example, the thermocouple Type B with a platinum 30% rhodium (+) composition may have a temperature range of 2,500 to 3,100 degrees Fahrenheit. Conversely, a platinum 6% rhodium (-) composition of the same thermocouple type may yield a similar temperature range.

Another example is a thermocouple type E with a chromel (+) composition. For this model, you may use it for handling temperature ranges of 200 to 1,650 degrees Fahrenheit. Still, consider the environment before using specific thermocouple types.

Uses of Thermocouples

Different thermocouple types may have diverse uses. Hospital thermometers, automotive technologies, and machines handling renewable energies might use thermocouples to help users detect changes in temperatures. Here are a few thermocouple types and their uses:

  • Type J

This thermocouple type may have an iron and Constantan leg. Various organizations in different industries find this model to be helpful in several operations. For example, it may be useful in reducing, oxidizing, and vacuuming atmospheres. Type J models may have durable constructions. Thus, these units may not require sensitive handling when installing them in other machines or industrial environments.

  • Type K

This thermocouple has a Chromel and Alumel composition for its wire legs. Consider using this type to oxidize or inert atmospheres with temperatures of up to 2,300 Fahrenheit. Companies may use this thermocouple model thanks to its relatively accurate and stable readings even at high temperatures.

  • Type N

Type N thermocouples may be akin to better Type K models. This type has a Nicrosil and Nisil composition for its wire legs. It also has a similar temperature range as the Type K. However, type N models might have better resistance than its type K counterparts thanks to its temperature cycling features. Furthermore, its hysteresis and green rot allow type N models to be more cost-effective units than type Ks.

  • Type T

A copper and Constantan composition reside in the wire legs of type T thermocouples. Like the type J models, type Ts help users reduce, oxidize, vacuum, and inert atmospheres. Still, this thermocouple class has excellent resistance against corrosion in several atmospheres. It may also offer high-stability readings at sub-zero temperatures.

  • Type E

For this thermocouple, it has one Chromel and one Constantan leg. Like the type T thermocouple, it may also be resistant to corrosion in various atmospheres. However, there’s one characteristic that may put type E thermocouples better than other models: Type Es may have the highest EMF per degree in comparison with different thermocouple types. Nonetheless, it might not be resistant to sulfurous environments.

  • Type C

Environments that have sweltering temperatures may use type C thermocouples. This model has a tungsten and rhenium composition for its wire legs. Organizations may use this thermocouple type in extremely high-temperature environments of up to 4,200 degrees Fahrenheit. While it can withstand high temperatures, this thermocouple may have a brittle construction. Proceed with caution when handling it as one false move might break the device.

Conclusion

Always consider the right thermocouple type when you want to read temperatures accurately in specific environments. For instance, consider the right thermocouple when reading temperature levels in automotive technologies and their hot engines. These devices may also activate gas shut-off modules aside from reading temperatures. Take time in researching the right model for the job to avoid complications.

Manage Trees With Sustainability In Mind

There is growing concern as forest land outside of conservation areas is steadily decreasing. There has been a disturbing reduction in primary forests of 40 million hectares in the last decade. The total area of forest within protected areas has increased by 94 million hectares in the past two decades and now accounts for 13% of the total of forests globally.

Tree healthcare for humans

Trees are well known for providing oxygen as a result of their photosynthesis process.  It is in fact the carbon dioxide (CO2) that is removed during this process therefore helping to mitigate the negative effects of burning fossil fuels ie. CO2 production.  The benefits to the world of this process make the existence and importance of the Amazon rainforest especially significant.

Trees benefit cities too

Not only are trees a beautiful addition to any city, they also serve a practical purpose by absorbing pollutants.  Their presence makes a city appear more vibrant and more friendly.  For example, San Francisco is home to 105,000 trees.  Tree planting should be kept in pace with tree mortality and removals.  A tree management plan is essential to ensure sustainability.

Tree management for woodland

Trees should be checked for health and also for the merchantability of the trees.  When areas of the woodland require thinning out it is useful to produce a product that has a commercial value.  This way waste management has been prioritized and has turned a Liability into an Asset.  The harvested wood/logs can be considered an asset and can be sold as fuel.  Always ensure trees are removed when over-crowding is an issue to allow for tree growth of the remaining trees.  The woodland is sustainable by including sufficient planting of new trees.

Maintaining the urban trees

Your arborist can advise you of local procedures and the law regarding your trees which if not properly managed can become a legal liability.  Some types of trees do not take well to heavy pruning, for example the Southern Live Oak is best not located in restricted areas where heavy pruning to clear avenues may be required.  It is better to grow it in a larger landscaped area where it can grow with minimal pruning.  They often reach 60 to 80 feet in height with a 60 to 100 foot spread.

The branches of Live Oak tend to droop as they grow so some careful pruning will be necessary especially as this type of growth can be a problem for vehicular or pedestrian clearance beneath.  Many trees are not permitted to be removed without obtaining a tree removal permit first.  This is good as it provides some protection for the trees.

Other tree varieties to grow with sustainability

The beautiful red maple is a great yard tree being very tolerant and is able to grow in nearly any conditions but especially in acid to neutral soils.  Plant away from paths etc as the roots can raise sidewalks if too close.  A good layer of organic mulch should be placed around the roots to feed and help retain moisture.

Presence of trees make a city appear more vibrant and eco-friendly

Another commonly found tree in the US is the Loblolly Pine.  When found in plantations it provides the perfect habitat for wildlife such as deer, squirrels making it a very sustainable choice.  Being a faster growing tree it requires more regular pruning.

Enjoy our future with sustainability for trees

Sustainability ensures we leave the world in a good state for future generations to enjoy, whilst still meeting the needs of the current population.  Keep your trees maintained moving forward and always pay attention to the type of tree and manage accordingly.  This way you can enjoy the many beautiful trees around you.

Bioenergy Developments in Malaysia

Malaysia is blessed with abundant renewable sources of energy, especially biomass and solar. Under the Eighth Malaysian Plan, renewable energy was added in the energy mix to unveil a Five-Fuel Strategy to achieve 5 percent contribution by 2005.

Among the various sources of renewable energy, bioenergy seems to be the most promising option for Malaysia. The National Biofuel Policy, launched in 2006 encourages the use of environmentally friendly, sustainable and viable sources of biomass energy. Under the Five Fuel Policy, the government of Malaysia has identified biomass as one of the potential renewable energy. Malaysia produces atleast 168 million tonnes of biomass, including timber and oil palm waste, rice husks, coconut trunk fibres, municipal waste and sugar cane waste annually. Being a major agricultural commodity producer in the region Malaysia is well positioned amongst the ASEAN countries to promote the use of biomass as a renewable energy source.

Malaysia has been one of the world’s largest producers and exporters of palm oil for the last forty years. The Palm Oil industry, besides producing Crude Palm Oil (CPO) and Palm Kernel Oil, produces Palm Shell, Press Fibre, Empty Fruit Bunches (EFB), Palm Oil Mill Effluent (POME), Palm Trunk (during replanting) and Palm Fronds (during pruning).

Malaysia has approximately 4 million hectares of land under oil palm plantation. Over 75% of total area planted is located in just four states, Sabah, Johor, Pahang and Sarawak, each of which has over half a million hectares under cultivation. The total amount of processed FFB (Fresh Fruit Bunches) was estimated to be 75 million tons while the total amount of EFB produced was estimated to be 16.6 million tons. Around 58 million tons of POME is produced in Malaysia annually, which has the potential to produce an estimated 15 billion m3 of biogas can be produced each year.

Malaysia is the world’s second largest producer of crude palm oil. Almost 70% of the volume from the processing of fresh fruit bunch is removed as wastes in the form of empty fruit bunches, palm kernel shells, palm oil mill effluent etc. With more than 423 mills in Malaysia, this palm oil industry generated around 80 million dry tonnes of biomass in 2010. Malaysia has more than 2400 MW of biomass and 410 MW of biogas potential, out of which only 773MW has been harnessed until 2011.

Rice husk is another important agricultural biomass resource in Malaysia with good potential for power cogeneration. An example of its attractive energy potential is biomass power plant in the state of Perlis which uses rice husk as the main source of fuel and generates 10 MW power to meet the requirements of 30,000 households. The US$15 million project has been undertaken by Bio-Renewable Power Sdn Bhd in collaboration with the Perlis state government, while technology provider is Finland’s Foster Wheeler Energia Oy.

Under the EC-ASEAN Cogeneration Program, there are three ongoing Full Scale Demonstration Projects (FSDPs) – Titi Serong, Sungai Dingin Palm Oil Mill and TSH Bioenergy – to promote biomass energy systems in Malaysia. The 1.5MW Titi Serong power plant, located at Parit Buntar (Perak), is based on rice husk while the 2MW Sungai Dingin Palm Oil Mill project make use of palm kernel shell and fibre to generate steam and electricity. The 14MW TSH Bioenergy Sdn Bhd, located at Tawau (Sabah), is the biggest biomass power plant in Malaysia and utilizes empty fruit bunches, palm oil fibre and palm kernel shell as fuel resources.

An Introduction to Biomethane

Biogas that has been upgraded by removing hydrogen sulphide, carbon dioxide and moisture is known as biomethane. Biomethane is less corrosive than biogas, apart from being more valuable as a vehicle fuel. The typical composition of raw biogas does not meet the minimum CNG fuel specifications. In particular, the COand sulfur content in raw biogas is too high for it to be used as vehicle fuel without additional processing.

Liquified Biomethane

Biomethane can be liquefied, creating a product known as liquefied biomethane (LBM). Biomethane is stored for future use, usually either as liquefied biomethane or compressed biomethane (CBM) or  since its production typically exceeds immediate on-site demand.

Two of the main advantages of LBM are that it can be transported relatively easily and it can be dispensed to either LNG vehicles or CNG vehicles. Liquid biomethane is transported in the same manner as LNG, that is, via insulated tanker trucks designed for transportation of cryogenic liquids.

Compressed Biomethane

Biomethane can be stored as CBM to save space. The gas is stored in steel cylinders such as those typically used for storage of other commercial gases. Storage facilities must be adequately fitted with safety devices such as rupture disks and pressure relief valves.

The cost of compressing gas to high pressures between 2,000 and 5,000 psi is much greater than the cost of compressing gas for medium-pressure storage. Because of these high costs, the biogas is typically upgraded to biomethane prior to compression.

Applications of Biomethane

The utilization of biomethane as a source of energy is a crucial step toward a sustainable energy supply. Biomethane is more flexible in its application than other renewable sources of energy. Its ability to be injected directly into the existing natural gas grid allows for energy-efficient and cost-effective transport. This allows gas grid operators to enable consumers to make an easy transition to a renewable source of gas. The diverse, flexible spectrum of applications in the areas of electricity generation, heat provision, and mobility creates a broad base of potential customers.

Biomethane can be used to generate electricity and heating from within smaller decentralized, or large centrally-located combined heat and power plants. It can be used by heating systems with a highly efficient fuel value, and employed as a regenerative power source in gas-powered vehicles.

Biomethane to Grid

Biogas can be upgraded to biomethane and injected into the natural gas grid to substitute natural gas or can be compressed and fuelled via a pumping station at the place of production. Biomethane can be injected and distributed through the natural gas grid, after it has been compressed to the pipeline pressure. In many EU countries, the access to the gas grid is guaranteed for all biogas suppliers.

One important advantage of using gas grid for biomethane distribution is that the grid connects the production site of biomethane, which is usually in rural areas, with more densely populated areas. This enables the gas to reach new customers. Injected biomethane can be used at any ratio with natural gas as vehicle fuel.

Biomethane is more flexible in its application than other renewable sources of energy.

The main barriers for biomethane injection are the high costs of upgrading and grid connection. Grid injection is also limited by location of suitable biomethane production and upgrading sites, which have to be close to the natural gas grid.

Several European nations have introduced standards (certification systems) for injecting biogas into the natural gas grid. The standards, prescribing the limits for components like sulphur, oxygen, particles and water dew point, have the aim of avoiding contamination of the gas grid or the end users. In Europe, biogas feed plants are in operation in Sweden, Germany, Austria, the Netherlands, Switzerland and France.

How to Create Presentations for Your Studies

Writing research seems to a lot of people to be a difficult task which makes them feel nervous and requires a lot of time, urging them to look for a legit essay writing service  like EssayShark or EssayBulls. However, it is only a part of the working process which also includes a preparation of useful presentation which can help the speaker to represent the information from the study in the most effective and understandable way.

We used to think that a process of development of the presentation is a difficult and complicated process because it seems impossible to choose only important parts of the study, as all parts which are included in this study we consider to be essential for the audience. Also, the problem with the preparation of presentation is related to the fact that the speech and slides should be structured in the way which is interesting to the people who will listen to it.

I think that the main task of the presentation is to demonstrate the findings from the study in the way which makes the audience to concentrate on the research and understand its importance, but it is impossible to do this if the presentation provokes the desire to fall asleep or contain too much unnecessary information. So, in this article, you will find a few tips which will make the process of creation of presentation to be easier for you, and with the help of these pieces of advice, you will get a better result in the process of demonstration the findings of your research to the audience.

Prepare a good plan

You know that for the good research you should develop a well-structured outline first of all, as it is a basic step which helps to make the working process to be easier and more effective. If you want to prepare a successful presentation you should develop a plan which will help you to structure the working process and the whole presentation as well. So, you need to understand the basic steps which you will follow during the working process on your presentation in order not to miss anything important for a good result in the end.

You need to analyze your research, to make sure that you understand the perspective which you want to present to the audience, and highlight the most essential parts of your study in order to use this information in your presentation.

The presentation as an additional tool

One of the biggest mistakes is done by people who prepare their presentation is the lack of understanding of the main function of the presentation. A presentation is an additional tool which helps you to represent your main ideas and findings to the audience. A lot of people perceive the information more effectively if they have visual materials which are related to the presented information.

Speech is the main part in the process of demonstration to the audience your findings, but a presentation is a tool which can help audience to see the most important facts or information on the screen in order to remember it in the most effective way. You have to understand that there is no necessity to put all your speech on slides, as people should not read your speech, but you can use pictures, graphics, and other visual materials in order to help the audience to understand better the information which you present to them. A lot of people put too much unnecessary information on slides, so the audience is distracted from the main points of the speech.

Design and visual effects

Presentation is not only about the content, but also it is about the way in which you represent this content to the audience. It is important to remember that a lot of people perceive information visually, so you should think about the design and visual effects such as transitions between slides in order to make the presentation to be perceived in a better way.

For the best choice in design, you should analyze the topic of your presentation. In the case of presentations for studies, it would be better not to choose too bright or too dark colors. It is important not to distract the audience from the information which you present to them, but make them focus on the main points. Also, if you use too much animation in transitions between slides, it will distract the audience as well or make them nervous. So, the best tip in this aspect of the preparation of presentation is based on total simplicity as design should be a helpful tool but not a distraction from the content of the presentation.

Content

Content of presentation consists not only of the information which you use but also of images and other visual effects. As it was stated above, presentation is a helpful tool which is developed to help people to perceive information using their visual senses. However, it is important to find a balance in your presentation. As we speak about presentations for studies, it is essential to remember that too many images or memes can be inappropriate in this situation, so you should use pictures in order to make your presentation less boring and more informative, but do not focus only on this visual effect.

In addition, you have to find a balance between the amount of text which you put on each slide and the number of images and graphics. The best way to represent information to the audience is to use bullet points in order to help them to define the main aspects of your research and understand better your findings. People cannot remember instantly a great amount of information, and they will memorize the information from your presentation partly, so you have to show them which parts are the most important and what they should understand at first.

Parting Shot

These tips can help you to create a presentation for your studies in a fast, easy, and effective way. A lot of people think that the process of preparation of presentation is based on the necessity to put the information from the speech or research on the slides, but it is related to the importance of visual perception. You should develop your speech and presentation in a way which will not be boring to your audience but will help them to understand your study more effectively.

In this process, everything matters: the choice of font, the number of slides, the order of slides, the choice of images, and visual effects with design. Balance is the most important thing in the process of preparation of presentation, so you should think about the content of the slides and design keeping this rule in mind. Also, try to think like your audience, and if you consider your presentation to be interesting and informative, it means that you did a great job.

Sugarcane Trash as Biomass Resource

cane-trashSugarcane trash (or cane trash) is an excellent biomass resource in sugar-producing countries worldwide. The amount of cane trash produced depends on the plant variety, age of the crop at harvest and soil and weather conditions. Typically it represents about 15% of the total above ground biomass at harvest which is equivalent to about 10-15 tons per hectare of dry matter. During the harvesting operation around 70-80% of the cane trash is left in the field with 20-30% taken to the mill together with the sugarcane stalks as extraneous matter.

Cane trash’s calorific value is similar to that of bagasse but has an advantage of having lower moisture content, and hence dries more quickly. Nowadays only a small quantity of this biomass is used as fuel, mixed with bagasse or by itself, at the sugar mill. The rest is burned in the vicinity of the dry cleaning installation, creating a pollution problem in sugar-producing nations.

Cane trash and bagasse are produced during the harvesting and milling process of sugarcane which normally lasts between 6 to 7 months. Cane trash can potentially be converted into heat and electrical energy. However, most of the trash is burned in the field due to its bulky nature and high cost incurred in collection and transportation.

Cane trash could be used as an off-season fuel for year-round power generation at sugar mills. There is also a high demand for biomass as a boiler fuel during the sugar-milling season. Sugarcane trash can also converted in biomass pellets and used in dedicated biomass power stations or co-fired with coal in power plants and cement kilns.

Currently, a significant percentage of energy used for boilers in sugarcane processing is provided by imported bunker oil. Overall, the economic, environmental, and social implications of utilizing cane trash in the final crop year as a substitute for bunker oil appears promising. It represents an opportunity for developing biomass energy use in the Sugarcane industry as well as for industries / communities in the vicinity.

Positive socio-economic impacts include the provision of large-scale rural employment and the minimization of oil imports. It can also develop the expertise necessary to create a reliable biomass supply for year-round power generation.

Recovery of Cane Trash

Recovery of cane trash implies a change from traditional harvesting methods; which normally consists of destroying the trash by setting huge areas of sugarcane fields ablaze prior to the harvest.  There are a number of major technical and economic issues that need to be overcome to utilize cane trash as a renewable energy resource. For example, its recovery from the field and transportation to the mill, are major issues.

Alternatives include the current situation where the cane is separated from the trash by the harvester and the two are transported to the mill separately, to the harvesting of the whole crop with separation of the cane and the trash carried out at the mill. Where the trash is collected from the field it maybe baled incurring a range of costs associated with bale handling, transportation and storage. Baling also leaves about 10-20% (1-2 tons per hectare) of the recoverable trash in the field.

A second alternative is for the cane trash to be shredded and collected separately from the cane during the harvesting process. The development of such a harvester-mounted cane trash shredder and collection system has been achieved but the economics of this approach require evaluation. A third alternative is to harvest the sugarcane crop completely which would require an adequate collection, transport and storage system in addition to a mill based cleaning plant to separate the cane from the trash .

A widespread method for cane trash recovery is to cut the cane, chop into pieces and then it is blown in two stages in the harvester to remove the trash. The amount of trash that goes along with the cane is a function of the cleaning efficiency of the harvester. The blowers are adjusted to get adequate cleaning with a bearable cane loss.

On the average 68 % of the trash is blown out of the harvester, and stays on the ground, and 32 % is taken to the mill together with the cane as extraneous matter. The technique used to recover the trash staying on the ground is baling. Several baling machines have been tested with small, large, round and square bales. Cane trash can be considered as a viable fuel supplementary to bagasse to permit year-round power generation in sugar mills.

Thus, recovery of cane trash in developing nations of Asia, Africa and Latin America implies a change from traditional harvesting methods, which normally consists of destroying the trash by setting huge areas of cane fields ablaze prior to the harvest. To recover the trash, a new so-called “green mechanical harvesting” scheme will have to be introduced. By recovering the trash in this manner, the production of local air pollutants, as well as greenhouse gases contributing to adverse climatic change, from the fires are avoided and cane trash could be used as a means of regional sustainable development.

Cane Trash Recovery in Cuba

The sugarcane harvesting system in Cuba is unique among cane-producing countries in two important respects. First, an estimated 70 % of the sugarcane crop is harvested by machine without prior burning, which is far higher than for any other country. The second unique feature of Cuban harvesting practice is the long-standing commercial use of “dry cleaning stations” to remove trash from the cane stalks before the stalks are transported to the crushing mills.

Cuba has over 900 cleaning stations to serve its 156 sugar mills. The cleaning stations are generally not adjacent to the mills, but are connected to mills by a low-cost cane delivery system – a dedicated rail network with more than 7000 km of track. The cleaning stations take in green machine-cut or manually cut cane. Trash is removed from the stalk and blown out into a storage area. The stalks travel along a conveyor to waiting rail cars. The predominant practice today is to incinerate the trash at the cleaning station to reduce the “waste” volume.
