Waste management has a profound impact on all sections of the society, and military is no exception. With increasing militarization, more wars and frequent armed conflicts, protection of the environment has assumed greater significance for military in armed conflicts as well as peacetime operations. Tremendous amount of waste is generated by military bases and deployed forces in the form of food waste, papers, plastics, metals, tires, batteries, chemicals, e-waste, packaging etc.
War on Waste
Sustainable management of waste is a good opportunity for armed forces to promote environmental stewardship, foster sustainable development and generate goodwill among the local population and beyond. Infact, top military bases in the Western world, like Fort Hood and Fort Meade, have an effective strategy to counter the huge amount of solid waste, hazardous waste and other wastes generated at these facilities.
Waste management at military bases demands an integrated framework based on the conventional waste management hierarchy of 4Rs – reduction, reuse, recycling and recovery (of energy). Waste reduction (or waste minimization) is the top-most solution to reduce waste generation at military bases which demands close cooperation among different departments, including procurement, technical services, housing, food service, personnel. Typical waste reduction strategies for armed forces includes
making training manuals and personnel information available electronically
reducing all forms of packaging waste
purchasing products, such as food items, in bulk
purchasing repairable, long-lasting and reusable items
Due to large fraction of recyclables in the waste stream, recycling is an attractive proposition for the armed forces. However, environmental awareness, waste collection infrastructure, and modern equipment are essential for the success of any waste management strategy in a military installation.
Food waste and yard waste (or green waste) can be subjected to anaerobic digestion or composting to increase landfill diversion rates and obtain energy-rich biogas (for cooking/heating) and nutrient-rich fertilizer (for landscaping and gardening). For deployed forces, small-scale waste-to-energy systems, based on thermal technologies, can be an effective solution for disposal of combustible wastes, and for harnessing energy potential of wastes. In case of electronic wastes, it can be sent to a Certified Electronics Recycling and Disposal firm.
Management options for military installations is dependent on size of the population, location, local regulations, budgetary constraints and many other factors. It is imperative on base commanders to evaluate all possible options and develop a cost-effective and efficient waste management plan. The key factors in the success of waste management plan in military bases are development of new technologies/practices, infrastructure building, participation of all departments, basic environmental education for personnel and development of a quality recycling program.
Military installations are unique due to more than one factor including strict discipline, high degree of motivation, good financial resources and skilled personnel. Usually military installations are one of the largest employers in and around the region where they are based and have a very good influence of the surrounding community, which is bound to have a positive impact on overall waste management strategies in the concerned region.
When titanium was first brought into widespread usage, it was lauded for its strong and weathering-resistant properties. Due to energy costs, production declined over the past 10 years; however, a new process established by the UK’s Dstl has reduced titanium processing time by 50%. The result – Cheap, low-energy titanium production.
Titanium is used in a startlingly diverse array of applications, too. From paint, to bikes, to eco friendly party glitter, you will likely encounter titanium in your day-to-day life more frequently than you’d notice. It’s good news, then, that titanium is being used to support positive environmental change in numerous ways.
Titanium taking over plastic
One of the foremost ways in which titanium is helping to improve our natural environment is through offering alternatives to polluting items. A great example of this is plastic replacement.
According to clean ocean advocates The Ocean Cleanup, there’s over 80m tonnes of plastic in the oceans. A large contributor to this is the plastic straw, which features at 11th in the list of Get Green’s most commonly littered plastics. Many manufacturers, by utilizing the non-rusting and sturdy quality of titanium tubes, have opted to replace drinking straws with titanium. Given the possibility of cheap, low energy tubes, this means ocean cleanliness can be improved and carbon emissions mitigated.
Taking titanium to the next level
The material properties of titanium are being taken to the next level by modern science. Another huge cause of carbon emissions and pollution is the plastic bottle. A key target for environmental plans, the reusable bottle industry grew to $7.6bn last year, according to Nielson.
Titanium has entered the market through a clever flexible bottle, with titanium a key component. The metal has again been chosen due to its resistant quality and the improving environmental impact of producing it.
Tackling the oxides
Oxides have been the main use of titanium for a while. Paint, ink, sunscreen, medicines, paper – there are countless products that use titanium oxide. Historically, the process for oxide extraction has been environmentally damaging, as has the product itself; for example, the USA’s National Park Service states that various sunscreens with Ti oxide will damage coral.
Many manufacturers are replacing plastic drinking straws with titanium.
Now, Titanium Oxide is likely to be brought into the green sphere, too. A novel new study published in the Journal for Pharmaceutical Sciences found that titanium oxide can be synthesized using bacteria, and that this could spell a much brighter future for the historically damaging extraction.
Titanium is a versatile and well renowned metal used in a huge range of applications. As such it’s not an easy proposition to remove it from the market on the grounds of environmentalism. However, through determined scientific study and consumer action, it’s becoming a figurehead in helping the public to use its quality and simultaneously protect the planet.
Zero Valent Iron (ZVI) was developed to eliminate chlorinated hydrocarbon solvents in the soil. Industrial solvents are replete with chlorinated hydrocarbon, so much toxic and bad for the environment. They get disposed in the soil along with other toxic elements to cause harm to our surrounding. In the current years, significant improvements have taken place in the realm of iron-based technology.
Zero Valent Iron can be effectively used in soil remediation
The result of years of research and significant improvement in the iron-based technology is the advent of nanoscale or polymer-supported iron-containing nanoparticles to remove contaminants from solvents and soil. This is all due to the high surface area to the volume ratio of such nanoscale particles that favor the reaction kinetics and sorption.
But, know one thing that high pressure drops may restrict fixed-bed column application. This is why we now have modified nanosized ferrous particles to facilitate arsenic removal. The fabulous reducing agent helps in pollution recovery, and thus it benefits our environment.
Applications of Zero Valent Iron
ZVI in recent times is used widely for wastewater treatment, groundwater, and soil treatment. If made through the physico-chemical process in combination, the ZVI may be very small particles, having a large surface area. ZVI is beneficial for the environment, for it has a strong reductibility, great purity, long aging property, and similar features.
Zerovalent Iron can boost the chlorine removal efficiency of the soil, groundwater, and six valent chromium. Thus, it reduces the time required for environmental remediation. Acting as a fabulous reducing agent, it facilitates pollution recovery. Indeed, you may also combine it to bioremediation to further improve the efficacy of environment pollution recovery. Use it in the soil, solvents and industrial wastewater confidently to get rid of the contaminants. The use of ZVI paves the way for pure water and soil.
What you should look for in ZVI?
Are you planning to procure zero valent elemental metallic ions for wastewater treatment or soil remediation? Zerovalent metals or ZVI has a wide range of applications that range from electrodes and trenches to filters. Yes! It helps in the water filtration process, and thus we have pure drinking water. It gets rid of every trace of impurity or contaminant from the solvent or soil. It is important to look for a reliable company to procure ZVI.
Watch out for the following properties of ZVI
The particles must be fine enough to be customized as per your application
Look for the great adsorption performance and sound chemical activity
A large surface area for that very strong reductibility
Make sure the duration of its effect is very long to reduce the injections
Very fine ZVI particles to remediate pollution and to save remediation time and effort
Must be environment-friendly, deprived of any toxic compound
Enhanced nitrate-removing potentialllu
Zero-valent metal has an enhanced nitrate removal capacity. It eliminates nitrate from the groundwater to facilitate remediation. Hence, biochar-supported ZVI can facilitate nitrate removal while the ones with wider pH can remove larger nitrates. Biochar composite eliminates nitrate from the groundwater without leaving any harmful by-products. But, biochar has a variable nitrate-removal capacity.
ZVI biochar has a potential to reduce nitrate by mediating the redox potential, the electron transfer, pH and thus facilitates enhanced removal or reduction of nitrate from the solvent or soil. Everything revolves around the logic of intensifying chemical reduction in order to eliminate nitrate from the soil or groundwater.
Nitrate and How it Accumulates
Nitrate is the form of nitrogen, which lies beneath the cultivable land. Nitrate is water soluble and may move through the soil quite easily. Owing to its high mobility, it moves to the groundwater table. Once it has moved to the groundwater table, it persists there and deposits to a very high level.
Thus, shallow groundwater is also at a risk of contamination from chemicals of land surfaces. This is a matter of concern, and indeed, nitrate in water may harm human health, aquatic life, livestock life and contaminate the surface water. We can say that it is not that harmful to adult humans, but it can significantly affect the health of the infants. It may reduce the level of oxygen in the blood to cause ‘blue baby’ disorder.
Hence, biological denitrification, ion exchange, and reverse osmosis are the treatment processes to handle this issue. The use of ZVI is a way to denitrification and the key to attaining a safe nitrate level in the water. A zero-valent metallic reduction is an effective way to refine dirty and polluted water. As soon as ZVI is placed in the flowing water or is added to the flowing water, there starts the process of oxidizing. The resultant chain reaction will purify water or remove the contaminants.
A Tool to Remediate Acid Mine Drainage
AMD or Acid Mine Drainage is the most common source of metal in places like the Appalachians, Tennessee, and Kentucky. It is important to remediate acid mine drainage for it is highly acidic and toxic. It is the major contributor to the arsenic environment and something needs to be done. AMD is a rich source of heavy and corrosive metals, acidic in nature. Biological treatment of Acid Mine Drainage is cost-effective, efficient and environment-friendly.
Biotechnological processes are an asset when it comes to treating Acid Mine Drainage in an effective manner. ZVI is environmentally sustainable. When it is very complicated and difficult to treat or remediate Acid Mine Drainage, ZVI eases the process. It gets rid of harmful elements or potentially hazardous substances from AMD to separate metal from acid and toxic compounds. There isn’t a need to abandon a mine site just because there are acidic metal deposits. Mine metals can be reclaimed with ZVI, and herein lays the environmental benefit.
Recycling of metallurgical waste
It is important to treat AMD or Acid Mine Drainage. The ecological solution to separate toxic metals, to reclaim water in large quantities is gaining a lot of attention. ZVI and zero valent metals save our natural resources and prepare the toxic metals for the recycling process. This is only possible through the separation of the acidic part.
We can recycle gallons of water that lay in the pond and other water bodies. It drops the acid level in the water and metal while also prevents heavy metallic reactions. When Acid Mine Drainage is one of the serious concerns in the realm of coal mining, zero valent metals prevent any exposure of sulfur-rich mineral to the water and atmospheric oxygen.
Zero-valent metals can help in the treatment of contaminated zones through the process of remediation. Zero valent iron is the highly reactive powder for remediation of wastewater and soil and works fabulously on environmentally contaminated areas. This remediation solution is highly efficient and benefits our environment in multiple ways.
Whether talking about recycling for a home or business, this type of service is extremely important for the environment. Waste has a negative impact on the environment and can cause pollution of many kinds. Most companies that offer both garbage and recycling services are very organized, and consumers are expected to be equally organized in sorting their waste and separating it from recyclable items.
Because the process of figuring out what can be recycled, many individuals and business owners find it is much easier to simply hire a waste management company.
Below are some questions to consider when looking for recycling services and reasons why hiring a waste management company can take the guesswork out of recycling.
What Kind of Recycling Service is Required?
This can mean anything from home to office to hazardous waste to syringe collection services. Some companies offer all types of recycling and provide the different skip bins necessary to mitigate these needs. It is important to contact the company and find out as much information that is needed to make an informed decision on how recycling is handled.
However, most companies will only offer a general list of items that can be recycled, including plastics, cardboards, glass, etc. This list will not be exhaustive, leaving many consumers to wonder what to do with items such as plastic bottle caps, milk cartons and the like. A waste management company will know the specific regulations for what can and cannot be recycled, eliminating the hassle for you.
What Can Be Recycled?
Bricks, wood, paper, metals, cardboard, plastics, concrete, and green waste can all be recycled.
Bricks – These are broken down and crushed in order to be made into new bricks.
Wood – Wood can be used again as a building material or can be processed into pulp or mulch. Recycling wood can limit the number of trees that are being cut down.
Paper – The process for this material mixes old paper with chemicals and water to break it down. It is then chopped, heated and broken down further into strands of cellulose. This substance is then called slurry or pulp and is further recycled into new paper.
Metals – Recycling metals will not alter its properties, the most common metals recycled are steel and aluminum.
Cardboard – This uses a process that reuses thick sheets of multilayered papers (cardboard) that have been discarded.
Plastics – The recycling process for plastics recovers waste or scraps of plastic and reprocesses them into useful products.
Concrete – This type of recycling is becoming more common and uses a process of reuse of the rubble for new construction endeavors.
Green Waste – This can be anything from leaves to grass trimmings to flower cuttings that can be decomposed and then recycled. This will in turn produce what is called green waste.
There are a number of items that can be recycled, but it is important to note that not all recycling pickup services will be able to process all the items mentioned above. Certain materials, such as concrete or wood, must be disposed of at specific facilities.
Recycling has unending benefits
For the average homeowner, this can mean having to locate the specific facility and transport the recyclable materials to them. A waste management company will have the contacts in the industry to know where to take any type of recyclable item and can take care of the transportation for you.
What Recycling Techniques Are Used, and Are They Legal and Ethical?
Concretes and Aggregates – This process would involve using a crushing machine and combining the concrete with bricks, asphalt, dirt and rocks. The smaller pieces will be used as gravel, crushed concrete can all be used as dry aggregate, which in turn can be used to make new concrete that will be free of contaminates.
Batteries – This type of recycling can be very difficult; all batteries must be sorted into groups of similar kinds and require. Older batteries contain cadmium and mercury, which are very harmful and must be handled very carefully.
Biodegradable Waste – This type of waste can be made into reusable material via the process of biological decomposition. The two mechanisms that help this to occur are composting or converting it into soil improver and biogas. The latter uses anaerobic digestion where organic wastes are broken down by microorganisms in a biogas plant.
Again, a waste management company will be able to guarantee that your recycling ends up in the right processing facilities and to ensure that it does get processed according to government regulations and ethical means. When the wrong items end up in recycling, this can lead to an entire batch being thrown out. A waste management company will make sure that the recyclable items are properly sorted, helping to ensure that your efforts to recycle do not go to waste.
What Are the Benefits of Recycling?
There are many benefits to using a recycling service. For instance, recycling conserves energy, reduces greenhouse gases, reduces water and air pollution, and conserves natural resources by reusing recycled materials. Protecting the environment is one of the most important things a home or business can do. When an individual or business chooses to recycle all different kinds of waste, it makes the world a better, less toxic place to live.
Not only does recycling help protect the world, it also reduces the need for extraction such as mining, logging and quarrying. It also reduces the need for processing and refining of raw materials. All these processes can contain harmful, substantial amounts of water and air pollution. Recycling will save this energy while reducing the amount of greenhouse gas, which in turn helps to attack climate change.
