Hi Asbestos Dumping: Is It the New 'Environmental Terrorism?'

Hi Asbestos Dumping: Is It the New 'Environmental Terrorism?'

- "There is an increasing number of asbestos dumping, which is occurring in public places."

About Asbestos:

Asbestos can cause cancer years down the line, without the person ever knowing that it's there and even if they did, there's no current cure that healthcare professionals are able to practice on patients. Mesthelioma is the known type of cancer that is a result of exposure to asbestos. There are further health complications that asbestos can cause to a person's health such as, lung problems and general health problems. Mesthelioma doesn't appear until 30-50 years down the line so although it does cause cancer and death, the only saving grace is that people are not affected straight away.

Recent Asbestos Dumping Case:

There has recently been a case of asbestos dumping in Holland-on-Sea, Ipswich road, Colchester, where a whole heap of asbestos was dumped partly in bags, the other parts scattered near public toilets. This has been rightly dubbed 'Environmental Terrorism' by the local paper; exposure to asbestos can cause cancer, the fact that asbestos has been dumped in a very public place could have made an impact on people's health, but this will be unknown until years down the line when its more than likely too late to prosecute the perpetrators for causing other people to contract cancer. No justice really; if those responsible were caught, there's no real way of prosecuting them for causing people cancer as it's an unknown fact and will remain that way for many years.

Is the person(s) who committed this shocking crime understand the implications of asbestos exposure can do or completely unaware. If unaware, does that indicate a lack of knowledge that people posses when it comes to asbestos and the dangers of being exposed to it? On the other hand, if the person(s) does understand the health risks to humans that asbestos causes, does this mean they are just pure evil; putting a person(s) health at risk to an extent where it's likely to give them cancer and a premature death is absolutely and undeniably shocking and should receive many years behind bars for doing so?

However, until years down the line, this cannot be proved or disproved, making dumping asbestos and being prosecuted for it, a complete grey area in the current justice system and to an extent understandable. People cannot be prosecuted for possibilities that something may happen, it must be factual and something must have occurred.

Asbestos Removal Regulations:

There are rules and regulations that have been put in place in order to help stop asbestos from causing unnecessary and painful deaths. However, these measures will not completely get rid of the asbestos fibres and with people now dumping asbestos where ever they like e.g. in public places, the problem may only get worse. Asbestos itself is not harmful if it isn't disturbed, but if it is accidentally or purposefully disturbed then this is when it becomes deadly and therefore, asbestos must be removed using correct methods, procedures and equipment.

There are strict laws when it comes to asbestos removal and this must be followed to the letter by any person or business whom is involved in the removal of asbestos. These laws were introduced in order to try minimise health risks due to the high proportion of buildings and materials contaminate by asbestos during removal.

How Easy is it to Disturb Asbestos?

Asbestos is extremely easy to disturb; a simple hole drilled into a wall that contains asbestos can be harmful for a person as the particles are tossed into the air and therefore, a chance of being breathed in by people in the vicinity.

Hi A Dark Side of Solar Power!!!

Hi A Dark Side of Solar Power!!!

The harshest criticism for fossil fuels has always been the horrible effect they have on the environment. Not only does retrieving the resource (coal, petroleum, natural gas) do irreparable damage to landscapes and ecosystems, but transporting it can be quite dangerous. And once the fuel has been spent, harmful byproducts clog the atmosphere and have far-reaching effects that scientists have only recently begun to quantify.

You know this, and I know this. And I know that you know that we all know this. This isn't going to be a recital of facts we know, ya know? But what about the negative environmental impacts our cultural shift to renewable energies, namely solar power, produce? There is a side to solar (PV) power that's rarely considered and not well understood.

Energy Payback Time (EPBT):

EPBT is the amount of time it takes a solar panel to collect the same value of energy that was expended in the panel's creation. It used to be that panels virtually never recaptured the amount of energy which was needed to create them, but that belief faded in the 1990s as the technology improved.

A significant amount of energy is spent producing, processing, and purifying materials for PV panels, as well as for the manufacture, transportation, and installation of the panel. The mathematical formula (.pdf) for determining the EPBT looks like this:

Rather than break down figures for areas with my limited text space, I'll just spoil the conclusion: the effectiveness of solar panels is severely affected by material efficiency and the location of the panel. In most of the United States, it takes almost two years before the panels begin to reduce emissions. At what latitude do solar panels stop making sense?

Environmental Waste:

Not surprisingly, China has been the leading manufacturer of PV panels worldwide by nearly fourfold. Despite this robust production rate, they're only second in PV power production (18,400 mW compared to Germany's 36k mW). What gives?

Frankly, China doesn't care about its environment and has little oversight on how companies dispose of industrial waste. And in consideration of the profit the industry is making, what regulations do exist are overlooked. U.S.-based PV panel manufacturers have a hard time disposing of toxic materials used in the production process. Chinese companies don't have the same difficulty, choosing to bury chemicals or flush them in public waterways. The result is a panel which was cheaper to produce and ship abroad.

Really, we're just burying the problem someplace else, hoping that a super-solution from future geniuses materializes in the meantime.

Wildlife Impacts:

The Ivanpah solar plant in utilizes 174,000 heliostats to reflect sunlight onto a centralized solar tower. The tower collects the sunlight, transfers it to heat, and boils water to begin the electricity production process. The plant is located in the Mojave Desert, away from population centers.

Human population centers, at least. While the imagery of a desert solar plant probably conjures images of dust and tumbleweeds, the area where the plant lives is much more lush than you might expect. When the plant was first announced, it incited considerable backlash because it was building on habitat that belonged to the endangered desert tortoise. The plant's construction was ultimately changed to help curtail its effects.

Now that the plant is up and running, an unforeseen consequence has occurred: an excessive number of bird deaths. Birds are lured to the area by insects or migration patterns, but once in the vicinity of the plant they're almost assured a hellish death. Estimates of up to 28,000 bird deaths a year have been attributed to the concentrated solar arrays, which blind and even ignite birds midflight. Officials are considering how to proceed with a megawatt and mega-money facility that may drive the extinction of entire species on its own.

The point isn't that solar power is harming our environment. Without a doubt, nearly any energy harvest strategy will conclude with negative environmental effects. But it shows that a long, long road of development must be traveled before our technology creates the sustainable utopia we envision. For now, we should probably maximize the efficiencies of the energy sources we have.

Hi Researchers use HIVE to test latest building methods.

Hi Researchers use HIVE to test latest building methods.

A new research facility in Wiltshire is set to 

advance the development of sustainable 

construction materials and systems.

Funded by EPSRC, the £1m HIVE facility will allow construction companies and researchers to conduct realistic, full-scale testing of their facade designs in open-air conditions.

HIVE, located at Bath University’s Building Research Park in Swindon, consists of eight cells that are insulated from one another, each with a single face left exposed to the external environment.

The cells themselves will let researchers analyse the environmental impact of construction materials including their energy efficiency, flood resilience, structural capability and internal air quality.

‘People are interested in looking at the latest iteration of their products and trying to compare them with previous iterations or with competitive products to see whether or not the performance is something to shout about,’ said Dr Mike Lawrence, director of the Building Research Park.

He cautioned, however, that related projects are beset with issues surrounding finding a suitable location to build, gaining planning permission and installing the infrastructure to carry projects out.

Dr Lawrence said: ‘[HIVE is] plug-and-play…we’ve already got the data loggers, all the infrastructure, weather stations, communications [etc.].

‘They can, on day one, start their programme, which saves between six months to a year of time.

‘At the other end when you’ve finished your programme, you often have to deconstruct your building and put everything back to where it started. Again, we’ve got processes where the whole thing can happen much more quickly and effectively.’

Sixteen platforms will be available alongside HIVE for researchers to construct pods of up to 125m³ enabling flexible testing of construction systems and performance.

‘We can whack [buildings] up very quickly because the foundations are already there and when the experiment’s finished take it down and put something else up straight away – all of the infrastructure is there,’ said Dr Lawrence.

Carbon footprint:

The construction industry is widely acknowledged as having a considerable carbon footprint, a situation that Dr Lawrence is keen to redress.

‘The construction industry is responsible for half of global emissions, that’s an enormous amount and big target to hit,’ he said. ‘Let’s try and hit it, let’s both improve its on-going performance but also…make a building with a lower carbon footprint actually embedded into it.

‘So instead of putting in lots of steel and concrete, let’s put in materials which have much lower environmental impact, or indeed where the energy input into building [a structure] is less than the energy stored within the fabric of that building if you convert it into carbon dioxide.’

 Inside the HIVE:

• a hygrothermal cell to evaluate movement of heat and moisture through buildings, energy efficiency, air tightness and acoustic efficiency;
• a double-height and width cell that can be used for flexible construction design, testing façades, internal walls and floors, together with a strong roof, allowing for load testing;
• a flood cell that can be used for testing the resistance of construction materials to high water levels or for testing technologies that resolve the effects of flood damage;
• a bladder cell that enables the testing of construction panels against horizontal loading such as wind load and geotechnical forces.

How Nanotech Technology is incorporated with HVAC advances?

Industrial Nanotech imparts how innovations with nano materials can improve HVAC processes.

The insulation and air quality efficiency of HVAC systems has not changed much in the past 50 plus years. However, new advancements in nanotechnology-based insulation and anti-microbial materials offer advantages that provide the ability to insulate in less space, increase longevity of performance, improve weathering and moisture resistance and increase air quality – all with an objective of affordability and cost-effectiveness.

WHAT ARE NANO MATERIALS?

Nanotechnology is simply the manipulation of materials at a smaller scale than was previously available. By manipulating matter at the nano scale, materials have the ability to be built from the atomic level up, with much less waste. Science has also found that materials can take on different attributes when you manipulate them at this scale, such as silver taking on anti-microbial properties.

Nano materials is one of the fastest growing branches of nano science and within this falls nano coatings. Coatings are being invented that have the ability to provide attributes such as heat resistance, rust prevention, resistance to contagions and a variety of other surface protection qualities.

IMPROVING HVAC INSULATION USING NANO COATINGS

Insulating HVAC systems is paramount to reducing building energy consumption and related greenhouse gas emissions. For years we have been trained to think that you need thickness in order to insulate. However, just as cell phones and computers have shrunk and yet become more powerful over the years, so has insulation.

The newest form of insulation incorporates a nano material with very low thermal conductivity into a clear, water-based acrylic latex to provide a thin film coating that can be painted onto a variety of substrates, such as duct work, piping and boilers, to insulate effectively and consistently.

One benefit that a thin film thermal barrier provides is the ability to resist infiltration from moisture, dirt, dust and other contaminates that typically cause degradation of fibrous insulation's like fiberglass or rock wool. By using a nanotechnology-based coating for the insulation of critical HVAC system parts, overall replacement and maintenance costs can be reduced and the ability to insulate outdoor and rooftop equipment without the issues that come with rain, snow and other weather exposure is provided.

Thermal insulation and protective nano coatings have been shown to reduce energy costs by between 10 and 40 percent, depending upon the application, with a consistent insulation value throughout the five- to 10-year lifespan.

REDUCING CONTAGIONS USING NANO COATINGS

Indoor air quality is another area where nanotechnology can assist in reducing contagions that may infiltrate an HVAC system. Building health is an increasingly important topic as it directly relates to the health of the workers inside any facility. Some of the advances in nano coatings address issues with mold and fungi growth and corrosion prevention, as well as provide anti-microbial properties.

Infiltration of mold or fungi into an HVAC system contribute to an unhealthy building. When traditional fibrous insulation becomes moist, it can become a breeding ground for these types of contagions. Other contagions can come from infiltration of outdoor air due to rusting duct work or piping, which leaves unwanted openings into the system.

Nano coatings are able to provide resistance to mold and fungi growth, prevent corrosion, and some are anti-microbial and can be used internally on duct work to reduce unwanted contagions. One anti-microbial coating incorporating nano silicon dioxide was shown in hospital trials to reduce bacteria by up to 50 percent on surfaces treated with the coating.

THE CHALLENGES OF THIS NEW TECHNOLOGY

As with any new and advanced technology there are challenges to adoption. One of these is that often measurement standards put in place and written into building codes were made to measure an older technology and do not always have the ability to measure new technological advancements. Standards tend to be behind industry innovations.

A challenge concerning the use of nano coatings for insulation is that the make-up of the material used allows the reduction of heat conduction in a thin layer and standards used, such as the R-value (R standing for resistance to heat flow), weigh thickness heavily into their equation of effectiveness, meaning they can’t be used to accurately reflect the energy saving ability of new thin film insulators.

To overcome this challenge, other building standard tests that measure direct heat conduction in energy units, such as watts or btus (British Thermal Units), that show the reduction in thermal transmission without skewing the result by thickness need to be used.

Another challenge is the fear factor any type of new technology brings, and nanotechnology is no stranger to this. People fear that nano-sized particles may infiltrate their skin or otherwise be a danger. However, nano scale particles are not used, but rather nanotechnology is incorporated in another way into materials, so there should be no fear of any infiltration of tiny particles. In addition, companies in the field offer health and safety testing to allay fears.

THE ADVANTAGES OF CHANGE

While you should do your homework before deciding on adopting any new technology for HVAC efficiency, it definitely can pay off to see what innovations are available from nanotechnology-based materials. Nanotechnology has now come out of the lab and has been making a difference in industry for at least a decade. It can enable huge improvements in energy efficiency, reduced greenhouse gas emissions, and overall increased longevity, health and air quality of a heating and cooling system.

The earlier adopters of these advanced technologies are already experiencing the benefits of their willingness to change old ways of thinking. As with all new technology, this eventually promotes the needed change in standards – and in the not too distant future, we should see nanomaterials being incorporated into standards and specifications, and being increasingly used as a mainstream choice for efficient HVAC processes.
