How is Agricultural Sector Dealing with Environmental Protection Laws in New Zealand?

If you take a look at sector shortages in New Zealand, you’ll find that agriculture and farming is one of the sectors struggling the most. There are long term shortages in the industry, so what’s putting people off from investing in this type of career path?

Although agriculture has dwindled in popularity since technology took over, there are other factors contributing to its decline. In New Zealand, there are strong environmental protection laws in place which need to be followed.

Here, we’ll look at how the agriculture industry deals with environmental protection laws in New Zealand.

What do the environmental protection laws cover?

The environmental protection laws in New Zealand are some of the strictest in the world. The country has earned a reputation for its clean, beautiful landscapes. A lot of its tourism is driven by its cleanliness and thriving ecosystem. This means the government has needed to introduce strict environmental protection laws to ensure New Zealand retains its pristine reputation. These laws include:

  • Resource Management Act 1991
  • Conservation Act 1987
  • Environment Act 1986
  • Ozone Layer Protection Act 1996

These are just a small number of the regulations and laws pertaining to the environment. There’s also a large list of related laws in New Zealand, making it difficult for businesses to keep up. This is especially true for those working within agriculture and industrial sectors.

New Zealand’s rivers under serious threat

Although New Zealand has developed a reputation as one of the most environmentally friendly countries in the world, it’s rivers are currently under serious threat. The environment ministry claims that two-thirds of the country’s rivers are now deemed un-swimmable. Even more worrying is that three-quarters of all of the country’s freshwater native fish are under threat of extinction.

In a bid to tackle the problem, the government has announced a rather ambitious plan. They are aiming to see a noticeable improvement over five years. Freshwater protection plans are being drafted and are expected to be put into place by 2025. In the meantime, immediate interim controls have been introduced. Swimming pools will be subject to increased water quality standards. However, it’s the farming sector which is going to see the biggest changes in regulations.

How are the agricultural and industrial sector dealing with the laws?

The agricultural and industrial sectors are currently struggling with the change in legislation. Although the government has pledged $229 million NZD to help farmers transition to the new laws, there’s still a lot of challenges the sector needs to overcome.

Farmers need to stop risky farm practices, such as allowing cows to stray to nearby waterways. Cow manure is partially being blamed for the increase in river pollution. New irrigation practices will also be denied unless farmers can prove it won’t harm the environment. There’s a lot of new laws being introduced which are causing issues for farmers and the industrial sector. Those working within the sector would do well to seek advice from specialists such as RSM.

Overall, New Zealand is making its environmental protection laws stricter over the next five years. This is already having an impact on the agricultural sector. However, seeking professional advice can ensure those working within the sector understand and adhere to the new legislation.

Thermocouples: Types and Uses

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.

How to Properly Scale Up Your Environmental Consulting Firm?

Environmental laws are important to keep our planet safe, especially from large industries that can unknowingly impact our world. Hence, these laws are strictly enforced, with punitive measures that are apt for its necessity. That’s why an environmental consulting firm is necessary for every business, to ensure the highest level of compliance in terms of such laws.

Now if you’re reading this article, then, most you most likely already know this. What you’re probably really interested in is how you can expand your business and cast a wider net across different states and possibly tap a global market. So here are a few things you must know to properly scale up your environmental consulting firm.

environmental-consultancy

Perfect your Fundamentals

The reason I started this article with a pretty basic definition about what an environmental consulting firm is tasked to do is because I want to remind you of the core value that such companies should impart on their clients. If you’re failing to do this, then it’s not yet time for you to scale up. Perfecting your fundamentals like proper project management and follow through is important because you should polish your current services before thinking about growing the business itself.

Any business for that matter must be scalable to an extent and for that you would need an organized business plan that can make your enterprise repeatable and enforceable no matter where you go.

Prepare a budget ready for any situation

This goes without saying but a sufficient budget is necessary if you really want to expand your business. It will take a big enough money for you to add to existing operations and to prepare for any emergency situation that may arise from it. However, if you do have a business plan and follow it by heart, you will most likely be able to use your funds more efficiently.

Know who to trust

Scaling up a consultancy firm relies heavily on how big a network you have already built for yourself over the years. This network will not only give you a reliable supply of clients wherever you go, but also a good team of suppliers that you can trust for all your operational needs.

For example, you definitely need to tap a construction materials supplier who can keep up with your demand as your business grows. You also need a good mobility partner for all transport needs such as renting your fleet that can travel far and wide to bring the materials, supplies, and manpower to any site across different states.

You can also expand by experimenting on trustworthy subcontractors that could do the job for you at a fraction of the cost. Let’s face it, it may take more managerial work but it removes a lot more responsibilities off your plate, which is pretty valuable once you’re already growing your business.

Improve your Efficiency

Improving your efficiency may be something you’d want to do before actually trying to scale up your business. But it’s also better if you can explore ways to automate processes like basic consultations and your financing. You can also try to develop an application or look for an existing software that can do most of the dirty work for you.

Know your End-Goal

What’s the point of expanding your consulting business? Do you want to make a bigger impact for the environment? Do you want to offer more jobs to people especially during this time? Or do you simply want to earn more money and make a name for yourself in the industry? To be honest, any of the aforementioned reasons are perfectly valid. However, you should once again keep in mind that your business thrives for a reason: you keep big corporations in check against possible environmental issues and make them sustainable. This means you have a social responsibility to keep that and ensure that this happens especially to all your clients.

Your end goal should guide you in how you will operate your consulting firm. There must always be an objective and an endpoint so you can properly rest on your laurels and won’t allow yourself to be a corporate slave for the rest of your life. Remember that there are ways you can let go especially if you feel like it’s already time.

Blindly pushing to expand your environmental consulting firm has serious repercussions not just for your company but also for the environment in general. So you must do your part and understand the list above so you can successfully scale up and be known as one of the best eco consultants not just in your area, but perhaps in the entire world.

Solutions for Maritime Industry Emissions

Until 2018, the maritime industry did not have a climate plan. While this may seem surprising, shipping tends to stay quiet about the environmental impacts of a global economy. Additionally, unlike other carbon-intensive sectors, it tends to quietly sail along unnoticed by consumers. It was not included in the Paris Agreement in 2016 and was not held accountable for its contribution to increased greenhouse gas emissions.

The International Maritime Organization laid out plans to cut emissions in half by 2050, an ambitious goal by one of the world’s main polluters. One of the main strategies to reduce CO2 emissions is to transition to more efficient fuel types. Most large shipping vessels operate with heavy fuel oil, which is rich in sulfur and extremely polluting. The International Maritime Organization is seeking to replace heavy fuel oil in 60,000 shipping vessels.

emissions-shipping-sector

However, consumer awareness surrounding the environmental cost of international shipping, coupled with innovative technology, may reduce the amount of pollution produced. The most likely solutions for reducing emissions from the maritime industry include transitioning to a more low-carbon fuel source, changing transport speeds, adopting sustainable shipping waste disposal strategies, transitioning to renewable energy and optimizing travel routes.

The Price of International Shipping

Shipping emissions are expected to grow exponentially between now and 2050. International shipping accounts for the majority of industrial pollution. Maritime regulations are significantly behind those for other carbon-intensive industries. It can be legally complicated to assign accountability to certain countries, especially in international waters. A handful of mega-ships can have the same level of greenhouse gas emissions as millions of cars, accounting for an incalculable portion of air and water pollution.

Our economy is global. When you look at the tags on your furniture, appliances, clothes and electronics, you may see dozens of countries around the world. Even our food, including perishable items like avocados and lettuce, are shipped internationally. Fresh produce can be shipped thousands of miles without spoiling using different refrigeration systems, such as air compressor technology. While these technologies make it easier to transport food, they come with a high-carbon impact. However, there are energy-efficient solutions to reduce carbon emissions in the shipping industry.

Energy-Efficient Solutions

Low-carbon technology is available in the shipping industry, but how it works in practice may be a different story. For example, switching from a high sulfur fuel oil to a low carbon option may have the greatest impact on reducing greenhouse gas emissions. Lowering sulfur oxide emissions is key to reducing the effects of international shipping.

However, switching oils will require the industry to identify pollution from the whole lifecycle, meaning that the use of fuel is only one part of its environmental impact. Accounting for this will be crucial in finding a sustainable solution for maritime industry emissions.

Another solution that is easier to implement than changing fuels is a practice called slow steaming. Slow steaming simply refers to slowing boats down, sometimes only by a few degrees. While it may not sound like much, changing a ship’s speed by a couple of kilometers can result in an 18% increase in fuel savings, which could be a gamechanger. However, industry leaders are worried that simply slowing down ships is not the answer, since it will result in a need for more vessels to keep the global economy moving.

Other energy-efficient solutions to maritime industry emissions include route optimization, renewable energy such as wind-assist technology and transitioning to all-electric ships. Norway, a main exporter in the petroleum and fish industries, has already tested an all-electric vessel and is actively working to optimize this technology to transition more ships away from fuel oil.

Time for Maritime to Go Green

The effort by the maritime industry to reduce greenhouse gas emissions is significant. Effective solutions to help curb climate change include transitioning to low sulfur fuel oils, changing ship speeds and investing in new technology such as renewable energy. However, consumer awareness will also play a vital role in the future of international shipping. The cost of a global economy is significant. Finding more sustainable methods of transporting goods across the ocean is imperative.

Torrified PKS: An Attractive Biomass Commodity in West Africa

Even though palm kernel shell has many similarities with wood pellets, it is not easy to reduce its size which makes it difficult for its optimum cofiring with coal in power plants and industries. Few years ago, Indonesia had exported PKS to Poland for cofiring purposes but because PKS was difficult to make powder (low grindability) it made cofiring performance poor, so the use of PKS for cofiring is currently discontinued.

palm-kernel-shells

 

To improve the quality of PKS, especially for the use of cofiring, PKS must be processed with torrefaction (mild pyrolysis). With the torrefaction process, it becomes easier to make powder from PKS, so that the desired particle size for cofiring is easier to obtain. Another advantage of the torrefaction process is that the caloric value of PKS will also increase by about 20%, Torrified biomass is hygroscopic which means ease in indoor as well as outdoor storage.

During the torrefaction process, PKS is heated at a temperature of around 230 to 300 °C in the absence of oxygen. With continuous pyrolysis technology, torrified PKS production can be carried out at large capacities. The need for biomass fuel for electricity generation is also large, usually requiring 10 thousand tons for each shipment. PKS torrified producers must be able to reach this capacity. The production of 10 thousand tons of PKS that are burned can be done per month or several months, for example, to reach 10 thousand tons it takes 2 months because the factory capacity is 5000 tons per month.

PKS-torrefaction

In general, the advantages of the PKS torrefaction process are as follows:

  • It increases the O/C ratio of the biomass, which improves its thermal process
  • It reduces power requirements for size reduction, and improves handling.
  • It offers cleaner-burning fuel with little acid in the smoke.
  • Torrefied PKS absorbs less moisture when stored.
  • One can produce superior-quality PKS pellets with higher volumetric energy density.

Pelletizing of torrefied PKS can be an option to increase the energy density in volume basis. The pelletizing process resolves some typical problems of biomass fuels: transport and storing costs are minimized, handling is improved, and the volumetric calorific value is increased. Pelletization may not increase the energy density on a mass basis, but it can increase the energy content of the fuel on a volume basis.

Africa, especially West Africa, which has many palm oil plantations and also the location where the palm oil trees originate, can supply torrified PKS to Europe to meet its rapidly-increasing biomass fuel demand.

In Africa, palm kernel shell is generally produced from PKO mills. CPO production is generally carried out on a small scale and only processes the fiber portion of the palm oil fruit. This palm oil mesocarp fibre is processed to produce CPO, while the nut that consist kernels and shells are processed elsewhere to produce the main product of PKO (palm kernel oil). PKO mills are usually quite large by collecting nuts from these small scale CPO producers. PKS is produced from this PKO mills.

The nut cracker machine separates kernel and shell

The distance between Africa and Europe is also closer than Europe to Malaysia and Indonesia. Currently, even though Europe has produced wood pellets for their renewable energy program to mitigate climate change and the environment, the numbers are still insufficient and they are importing wood pellets from the United States and Canada in large quantities. European wood pellet imports are estimated to reach more than 1.5 million tons per year. Torrified PKS from West Africa can help in meeting the biomass fuel demands for power plants across Europe.

Torrefaction of Biomass: An Overview

To improve the quality of biomass, especially for cofiring purposes, biomass waste can be processed with torrefaction (also known as mild pyrolysis). With the torrefaction process, it becomes easier to make powder (high grindability) so that the desired particle size for cofiring of biomass is easier to obtain. Another advantage of the torrefaction process is that the caloric value of biomass increases by about 20%. Torrified biomass is essentially hydropobic which means ease in storage including outdoor storage. This condition also makes it easier to handle and use, in addition to reduction in transportation costs.

torrefaction-of-biomass

What is Torrefaction

Torrefaction, which is currently being considered for effective biomass utilization, is also a form of pyrolysis. In this process (named for the French word for roasting), the biomass is heated to 230 to 300 °C without contact with oxygen. For comparison, pyrolysis of biomass is typically carried out in a relatively low temperature range of 300 to 650 °C compared to 800 to 1000 °C for gasification. Torrefaction is a relatively new process that heats the biomass in the absence of air to improve its usefulness as a fuel.

Torrefaction, a process different from carbonization, is a mild pyrolysis process carried out in a temperature range of 230 to 300 °C in the absence of oxygen. During this process the biomass dries and partially devolatilizes, decreasing its mass while largely preserving its energy content. The torrefaction process removes H2O and CO2 from the biomass. As a result, both the O/C and the H/C ratios of the biomass decrease.

steps-in-biomass-torrefaction

Advantages of Biomass Torrefaction

Torrefaction of biomass improves its energy density, reduces its oxygen-to-carbon (O/C) ratio, and reduces its hygroscopic nature. Torrefaction also increases the relative carbon content of the biomass. The properties of a torrefied biomass depends on torrefaction temperature, time, and on the type of biomass feed.

Torrefaction also modifies the structure of the biomass, making it more friable or brittle. This is caused by the depolymerization of hemicellulose. As a result, the process of size reduction becomes easier, lowering its energy consumption and the cost of handling. This makes it easier to cofire biomass in a pulverized coal-fired boiler or gasify it in an entrained-flow reactor.

Another special feature of torrefaction is that it reduces the hygroscopic property of biomass; therefore, when torrefied biomass is stored, it absorbs less moisture than that absorbed by fresh biomass. For example, while raw bagasse absorbed 186% moisture when immersed in water for two hours, it absorbed only 7.6% moisture under this condition after torrefying the bagasse for 60 minutes at 250 °C (Pimchua et al., 2009). The reduced hygroscopic (or enhanced hydrophobic) nature of torrefied biomass mitigates one of the major shortcomings for energy use of biomass.

In biomass, hemicellulose is like the cement in reinforced concrete, and cellulose is like the steel rods. The strands of microfibrils (cellulose) are supported by the hemicellulose. Decomposition of hemicellulose during torrefaction is like the melting away of the cement from the reinforced concrete. Thus, the size reduction of biomass consumes less energy after torrefaction. During torrefaction the weight loss of biomass comes primarily from the decomposition of its hemicellulose constituents. Hemicellulose decomposes mostly within the temperature range 150 to 280 °C, which is the temperature window of torrefaction.

torrified-biomass

As we can see from figure above, the hemicellulose component undergoes the greatest amount of degradation within the 200 to 300 °C temperature window. Thus, hemicellulose decomposition is the primary mechanism of torrefaction. At lower temperatures (< 160 °C), as biomass dries it releases H2O and CO2. Water and carbon dioxide, which make no contribution to the energy in the product gas, constitute a dominant portion of the weight loss during torrefaction.

Above 180 °C, the reaction becomes exothermic, releasing gas with small heating values. The initial stage (< 250 °C) involves hemicellulose depolymerization, leading to an altered and rearranged polysugar structures. At higher temperatures (250–300 °C) these form chars, CO, CO2, and H2O. The hygroscopic property of biomass is partly lost in torrefaction because of the destruction of OH groups through dehydration, which prevents the formation of hydrogen bonds.

Advantages of Used Cooking Oil Recycling

Used cooking oil can be easily recycled. All that is required the availability of a recycling plant and the used cooking oil to recycle. It is not a difficult process and anyone who would want to venture into the industry can quickly learn how to do it. They can then source for the used cooking oil and they are in the business of recycling.

Here are some advantages of used cooking oil recycling.

For your business

If you own a business, used cooking oil recycling is here to help you. Used cooking oil can be recycled to become fuel. If you are in the transportation business, you now have cheaper fuel for your trucks.

used-cooking-oil

Further, in the agriculture industry, used oil recycling can be used to develop high quality organic fertilizer. This is fertilizer that you can trust to not only help produce healthy and nutritious crops but to also help balance and improve your soil in the long run. Organic fertilizer is much cheaper, and you can therefore make significant savings as you farm.

For your home

At home, used cooking oil recycling has numerous benefits. You will never again have your kitchen sink and drainage clogged by used cooking oil. Many people drain their used cooking oil down the sink which leads to clogging.

When you accept to be part of the people who want to have used cooking oil recycled, your recycling team will give you a container in which to pour your used cooking oil. Then you will agree on a day and time that they will come to collect it and leave you with another empty container.

For the environment

Another advantage of recycling used cooking oil is felt in the environment.

In many cities and municipalities, you will find numerous drainage systems full and overflowing.

A major cause for this pollution is used cooking oil. When it is drained in the sink at home and in restaurants, it gets into the sewage system, where it causes blockages that lead to overflow of sewage onto the city roads.

In addition to sinks, many landfills have lots of poorly disposed of used cooking oil. Recycling helps develop better methods of disposal, ensuring that none of the oil finds its way to landfills.

Recycled used cooking oil is also used as an alternative to biodiesel. It is much cheaper and easier to produce and does not affect the price and supply of food in a country or region.

For the economy

Recycling used cooking oil is also a boon to the economy.

With an improvement to the environment, it is likely that the country gets cleaner. This means that it can attract people from other countries to live, work and invest in your clean country.

biofuel-UCO

Used cooking oil recycling also creates jobs for hundreds of people. It creates new jobs for the teams of people collecting the used oil from homes and restaurants. It creates high level jobs for the scientists who understand the chemistry of turning used cooking oil into soap or fertilizer.

With the creation of new jobs, the economy will have more people engaged and more money circulating in it. As a result, there will be significant economic growth in the country driven by used oil recycling.

For your pets

Used oil recycling also has significant advantages to your pets and animals. Used cooking oil can be recycled and turned into healthy, nutritious, organic animal and pet feeds.

Recycled used cooking oil creates high quality fish feeds and dog food. It also creates high quality pig and cattle feed.

Conclusion

Recycling used cooking oil is full of advantages. It can be converted into many things that are useful at home and in industry. It helps bring about a cleaner environment with fewer overflowing drainage systems clogged by used cooking oil that was drained down the sink. It also contributes significantly in developing organic farming affordably.

The Technology Revolutionizing Commercial Waste Management

Every single one of us can do something to improve our impact on the planet, but it is a given that businesses of all sizes have a bigger footprint than families – commercial accounts for 12% of total greenhouse gas emissions. A big factor of that is waste management. From the physical process of picking up garbage, to the methane-released process of decomposition, there are numerous factors that add up to create a large carbon footprint.

Between hiring green focused waste management solutions and recycling in a diligent fashion, there are a few technologies that are helping to break down the barrier between commercial waste management and an environmentally positive working environment.

Cleaning up commercial kitchens

A key form of commercial waste is food waste. Between the home and restaurant, it is estimated by the US Department of Agriculture that 133 billion pounds of food is wasted every year. Much will end up in the landfill. How is technology helping to tackle this huge source of environmental waste? Restaurants themselves are benefiting from lower priced and higher quality commercial kitchen cooking equipment, that helps to raise standards and reduce wastage.

Culinary appliances for varied cuisines also benefit from a new process being developed at the Netherland’s Wageningen University. A major driver of food waste is rejected wholesale delivery, much of which will be disposed of in landfill. The technology being developed in Holland aims to reduce wastage by analyzing food at the source, closer to where recycling will be achievable.

Route optimization

Have you ever received a parcel from an online retailer only to find the box greatly outsizes the contents? On the face of it, this is damaging to the environment. However, many retailers use complex box sorting algorithms. The result is that the best route is chosen on balance, considering the gas needed to make the journey, the amount of stock that can be delivered and the shortest route for the driver. This is an area of intense technological innovation.

The National Waste & Recycling Association reported in 2017 on how 2018 would see further advances, particularly with the integration of artificial intelligence and augmented reality into the route-finding process.

Balancing the landfill carbon footprint

It is well established that landfills are now being used to power wind turbines, geothermal style electricity and so on. They are being improved to minimize the leachate into groundwater systems and to prevent methane escaping into the atmosphere. However, further investigation is being pushed into the possibility of using landfill as a carbon sequester.

AI-based waste management systems can help in route optimization and waste disposal

Penn State University, Lawrence Berkeley and Texas University recently joined together to secure a $2.5m grant into looking into the function of carbon, post-sequestration. This will help to shed light on the carbon footprint and create a solid foundation on which future technology can thrive.

Businesses of all sizes have an impact on the carbon footprint of the world. The various processes that go into making a business profitable and have a positive impact on their local and wider communities need to be addressed. As with many walks of life, technology is helping to bridge the gap.

Shedding Light on Non-Destructive Testing with Ultraviolet Lamps

Non-destructive testing (NDT) can be simplistically described as a method used to conduct an inspection without moving or breaking the item or surrounding area under examination. Although not limited to medicine, aerospace, and industry, these three large sectors are particularly dependent on non-destructive inspection methodologies. One of the most helpful tools for NDT is the Ultraviolet (UV) lamp. Let’s take a brief look at the presence of UV lamps in NDT settings.

Non-destructive testing is a broad field

The definition of NDT can be quite broad unless one limits its description to a test, evaluation, or inspection, in a particular field of engineering or medicine. As well, the type of inspection that is required also comes from a long list of possibilities.

Non Destructive Testing

Fluorescent Magnetic Particle Inspection (FMPI or MT) and Fluorescent Penetrant Inspection (FPI or PT) are strongly associated with the use of fluorescent lighting and NDT.

Let the light come in

UV light is longer than X-rays, and shorter than visible white light, placing it into the 10 to 400 nm wavelength range. Known as black light, non-visible UV light can be harmful. The shorter UV-C rays, up to 290 nm, however, rarely reach the earth, and this is fortunate. Also be wary of UV-B rays, which are responsible for sunburns. The longer rays of UV-A, between 320 and 400 nm, are the least dangerous to humans.

In the past, magnetic particle penetrants used a mercury base, which became fluorescent with a UV-A light of 365.4 nm. This led to the requirement of today’s UV light sources for NDT. The standard requirement for a peak wavelength is between 360 – 370 mm.

The UV lamp advantage

One aspect of UV lighting that gives it the edge is that it provides visibility into the area under inspection where otherwise, there is none. The magnetic particles or penetrants that are applied to the surfaces of the areas to be inspected become fluorescent, providing visibility into the tiniest of flaws, such as cracks, breaks, and positioning changes.

What to look for in a UV lamp

There are UV lamps and then there are UV lamps. To achieve the most efficient, successful, and safe examinations, it is important to choose the correct UV lamp for the task at hand.

LED illumination

UV LED lamps are highly recommended for non-destructive testing. In fact, for the most part, LED lamps have replaced incandescent and fluorescent lamps, which may not be easily available in the near future.

UV Lamp

However, some legacy UV lamps can be modified to accept LED bulbs. UV LED lamps are lighter, making them very manageable. The bulbs are long-lasting, not prone to fading, and can be housed in cooler casings.

Handheld or stationary

The advantage of handheld UV LED lamps is, of course, their portability and their low energy consumption. However, unlike their predecessors, the mercury vapor bulbs, they do not offer the intensity and the wide beams that are required in some inspections.

Meeting the challenge, some UV lamp producers are using LED lighting to create stationary overhead lamps with intense, wide beam coverage, and adaptable frames, allowing easy vigilance over production in assembly lines. This is a low-cost alternative to frequently-replaced fluorescent bulbs.

The importance of a filter

With a peak wavelength between 360 – 370 nm, violet tail emissions of visible light above 400 nm can mask flaws and cracks with light glare. A filter improves visibility by providing more contrast.

Additional considerations

Science and engineering are always in flux. Similarly, developments in the field of non-destructive testing brings with it much to consider.

  • With the introduction of LED bulbs in UV light sources, dangers resulting from potential accidents in non-invasive fault-seeking, are no longer concerns. Burns resulting from filaments in mercury vapor are becoming a thing of the past. With less electrical demands from LED bulbs, power supplies can be lightweight, making the lamp easier to handle in tough conditions.
  • Just the fact that mercury will no longer be needed is enough of a cause for celebration.
