Towards Sustainable Pharmaceutical Management

The pharmaceutical industry has a substantial impact on the environment, especially when the materials used to make them and the chemicals that comprise make their way directly into the environment. The pharmaceutical industry at large as well as average consumer can take steps to make of use of medicine more sustainable through both significant and relatively minor changes.

Medicines and the Environment

The drugs that we consume naturally enter our environment as our body turns them to waste. This issue becomes exacerbated when people intentionally dispose of unused medicine by flushing it down the drain.

Although our water treatment systems are designed to take contaminants out of our wastewater before we re-introduce to the natural environment, some still get through. These contaminants, which include those in medications, can damage the ecosystems they end up in.

High levels of estrogen in waters due to birth control, for example, can hamper the ability of fish to reproduce, reducing their population size. Once those chemicals find their way into the water, they enter the food chain and eventually impact animals that live on land too, including humans.

Plants will absorb the chemicals from medications. Animals then eat these plants or drink the water and ingest the contaminants. Humans might drink the water or eat the plants or animals, making pollution from pharmaceuticals a human health hazard as well. This problem becomes worse in the summer when livestock such as cattle require two to three times as much water as they do during other times of the year.

Proper Disposal of Medicines

If you have unused medications that you need to get rid of, don’t flush them down the drain or throw them straight into the trash. The U.S. Food and Drug Administration (FDA) recommends one of several other options for the safe and sustainable disposal of medicines.

Some communities have drug take-back programs that the Drug Enforcement Administration (DEA) approves. Some pharmacies also allow you to mail in or dispose of unused medications at kiosks. The DEA also organizes a national drug take-back day.

Although certain medications have recommendations on the label to flush them, you can dispose of the majority of them in your regular trash at home. The FDA recommends mixing them with something unpalatable such as dirt, kitty litter or coffee grounds in a plastic bag that you can seal. This disguises the drugs and prevents pets from getting into them. You can then throw the bag away.

If you are a throwing away a prescription medication container, be sure to scratch out all potentially identifying information to protect your privacy and identity.

Using Medicines More Sustainably

Another option for reducing the impact your use of medicine has on the environment is to use less of it or use more environmentally friendly medications.

To use less medicine, only use it when you truly need it and try substituting natural remedies for pharmaceuticals. Reach for naturally derived treatments such as essential oils, vitamins, herbs or a cup of hot tea. Always consult with your doctor before changing your medication regimen.

As a long-term strategy, regular exercise and a healthy diet can do wonders in improving your overall health and decreasing your need to take medicines.

Sustainability from the Industry’s Perspective

Of course, making the pharmaceutical industry more sustainable isn’t the sole responsibility of the consumer. The industry can also change its practices to manage pharmaceuticals in a more environmentally friendly fashion.

One aspect of this involves energy use. The manufacturing and transportation of medications can be extremely energy-intensive. By using energy more efficiently and using cleaner energy, drug companies can reduce their environmental impact.

Pharmaceutical industry can change its practices to manage pharmaceuticals in a more ecofriendly manner.

These corporations can also make an effort to include more eco-friendly substances in their medications. While they may not be able to remove every non-natural chemical from their products, they can offer greener alternatives to consume and look into reducing the presence of damaging substances as much as possible.

This applies not only to the organizations closest to the consumers but to the entire supply chain.

Medications are often vital to our health, but it can also have a negative impact on the health of our environment. Taking steps to manage pharmaceuticals more sustainably can enable us to protect our own well-being as well as that of our environment.

Recycling of Lead-Acid Batteries in Developing Countries

Lead-acid batteries (also known as LABs) are a common item in our daily lives. Once the lead of the battery is timed out, we have no option but to dump it because it has no use for us anymore, but the copper plates in the battery remain reusable which can be used for recycling. There are some disagreements about the benefits of recycling battery, say alkaline battery, over simple disposal because the mercury in the battery no longer exists and the disposal material is abundant and non-toxic. But for automotive batteries the scenario is different in terms of benefits. The recycling of this type of battery holds both economic and environmental benefits.

The reusable material from the used battery is removed and recycled which reduces the needs for raw materials which is originally imported from abroad. It creates a balance payment and cost. In addition to this there can be considerable environmental impact during mining processes such as emission from smelting of sulfide ore, copper, nickel, and cobalt and this can be eliminated if recycling can be introduced.

Dangers of Lead-Acid Batteries

LABs generally consist of both sulphuric acid and large amount of lead which is not only corrosive but also a good carrier for soluble lead and lead particles. Lead is highly toxic metal which causes a wide range of adverse health effect especially on young children. If one gets expose excessively to lead it can cause damage to brain and kidney, impair hearing, and can led to various other associated problems. On an average an automobile manufactured contain about 12kg of lead, in which about 96% of lead is used in lead acid battery and remaining 4% is used in other applications like wheel balance weight, protective coating and variation dampers.

Both lead and cadmium are harmful for human health and environment. This toxic substances seeps into the soil, groundwater and surface water through landfill and also releases toxins into the air when they are burnt in municipal waste incinerators. Moreover cadmium can be easily absorbed by the pant root and get into the fruits, vegetables, and waters are consumed by animals and human beings, they can fall to prey to a host of ill effects. Studies have shown that nausea, excessive salivation, abdominal pain, liver and kidney damage, skin irritation, headaches, asthma, nervousness, decreased IQ in children, and sometimes even cancer can result from exposure to such metals for a sufficient period of time.

Need for Effective Control Measures

In a battery recycling plant, effective control measures need to be implemented, both to protect the health of workers and to prevent pollution of the environment. Good plant design, with reduction of the potential for the emission of contaminating substances is of utmost importance and the newer smelting processes are inherently much cleaner than traditional blast furnaces.

Pollution abatement technologies, including the treatment of exhaust gases and liquid effluents, need to be installed. Those mostly exposed to releases within the plants are the workforce. Control measures such as maintaining minimum standards of air quality within the works, medical surveillance of employees, use of protective equipment, and provision of conditions of good hygiene in general, is necessary to avoid occupational lead exposure. However, few government/non-governmental steps have been taken yet; rather this practice is a traditional trading system as prevail in the society.

Positive and Negative Impacts

In developing countries such as Bangladesh, recycling or reusing of used lead-acid batteries has both positive and negative impact on environment. Positive impact is that, if battery is recycled in proper and in sustainable manner it saves environment from toxic material of battery, otherwise battery waste is dumped into the landfills. Negative impact is that if recycling is not done in sustainable manner emits gases produced from battery recycling has adverse impacts on environment and human being.

In a battery recycling plant, effective control measures are required to safeguard public health and environment.

Direct recycling process should be banned as it has adverse impact on environment. As it is an illegal process, shopkeepers perform this process in hidden way. Government should impose the law and regulation strictly in this occurrence. This information can be used for advertising material highlighting the environmental benefits of recycling or reusing encourages the purchasing of old lead acid battery. It will accelerate the selling rate of old battery.

Importance of Awareness

Necessary steps should be taken to increase awareness about environmental impacts of used lead acid batteries. Proper instruction should be provided among the general mass. It will also increase reusing of old battery. Battery regeneration is a unique process specially designed to revive the lost capacity of batteries and give priority to choose secondary battery. Battery Reuse Centre can be developed for effective reuse and recycle.

The aim to divert reusable battery, donated by the public, which often could have been destined for landfill and instead provides a much needed source of low-cost battery to those in need. The battery reuse service encourages volunteer involvement and trainee placements in all aspects of its operation. Awareness program (posters, pamphlets, TV & radio commercials, road-shows, website, exhibitions, talks), infrastructure, information center, tax rebates for manufacturers should be taken to increase recycling or reusing of old battery.

Carbon Black: Promise and Potential

Carbon Black is a commercial form of solid carbon that is manufactured in highly controlled processes to produce specifically engineered aggregates of carbon particles that vary in particle size, aggregate size, shape, porosity and surface chemistry. Carbon Black typically contains more than 95 % pure carbon with minimal quantities of oxygen, hydrogen and nitrogen.

In the manufacturing process, Carbon Black particles range from 10 nm to approximately 500 nm in size. These fuse into chain-like aggregates, which define the structure of individual Carbon Black grades.

What is Carbon Black

Carbon Black is used in a diverse group of materials in order to enhance their physical, electrical and optical properties. Its largest volume use is as a reinforcement and performance additive in rubber products.

In rubber compounding, natural and synthetic elastomers are blended with Carbon Black, elemental sulphur, processing oils and various organic processing chemicals, and then heated to produce a wide range of vulcanized rubber products. In these applications, Carbon Black provides reinforcement and improves resilience, tear-strength, conductivity and other physical properties.

Carbon Black is the most widely used and cost effective rubber reinforcing agent (typically called Rubber Carbon Black) in tire components (such as treads, sidewalls and inner liners), in mechanical rubber goods (“MRG”), including industrial rubber goods, membrane roofing, automotive rubber parts (such as sealing systems, hoses and anti-vibration parts) and in general rubber goods (such as hoses, belts, gaskets and seals).

Applications of Carbon Black

Besides rubber reinforcement, Carbon Black is used as black pigment and as an additive to enhance material performance, including conductivity, viscosity, static charge control and UV protection. This type of Carbon Black (typically called Specialty Carbon Black) is used in a variety of applications in the coatings, polymers and printing industries, as well as in various other special applications.

Actually, after oil removal and ash removal processing from tire pyrolysis, we can get high-purity commercial carbon black, which can be used to make color master batch, color paste, oil ink and as addictive in plastic and rubber products. Besides, after activation treatment, the carbon black will become good materials to produce activated carbon.

In the coatings industry, treated fine particle Carbon Black is the key to deep jet black paints. The automotive industry requires the highest black intensity of black pigments and a bluish undertones.

Carbon Black has got a wide array of applications in different industries

Small particle size Carbon Blacks fulfill these requirements. Coarser Carbon Blacks, which offer a more brownish undertone, are commonly used for tinting and are indispensable for obtaining a desired grey shade or color hue.

In the polymer industry, fine particle Carbon Black is used to obtain a deep jet black color. A major attribute of Carbon Black is its ability to absorb detrimental UV light and convert it into heat, thereby making polymers, such as polypropylene and polyethylene, more resistant to degradation by UV radiation from sunlight. Specialty Carbon Black is also used in polymer insulation for wires and cables. Specialty Carbon Black also improves the insulation properties of polystyrene, which is widely used in construction.

In the printing industry, Carbon Black is not only used as pigment but also to achieve the required viscosity for optimum print quality. Post-treating Carbon Black permits effective use of binding agents in ink for optimum system properties. New Specialty Carbon Blacks are being developed on an ongoing basis and contribute to the pace of innovation in non-impact printing.

Waste Management in Food Processing Industry

Food processing industry around the world is making serious efforts to minimize by-products, compost organic waste, recycle processing and packaging materials, and save energy and water. The three R’s of waste management – Reduce, Reuse and Recycle – can help food manufacturers in reducing the amount of waste sent to landfill and reusing waste.

EPA’s Food Recovery Hierarchy

EPA’s Food Recovery Hierarchy is an excellent resource to follow for food processors and beverage producers as it provides the guidance to start a program that will provide the most benefits for the environment, society and the food manufacturer.

Notably, landfill is the least favored disposal option for waste generated in food and beverage producers worldwide. There are sustainable, effective and profitable waste management options including:

  • making animal feed,
  • composting to create nutrient-rich fertilizer,
  • anaerobic digestion to produce energy-rich biogas,
  • recycling/reusing waste for utilization by other industries,
  • feeding surplus food to needy people

Waste Management Options

Food manufacturers has a unique problem – excess product usually has a relatively short shelf life while most of the waste is organic in nature. Food waste created during the production process can be turned into animal feed and sold to goat farms, chicken farms etc. As far as WWTP sludge is concerned, top food manufacturers are recycling/reusing it through land application, anaerobic digestion and composting alternatives.

Organic waste at any food processing plant can be composted in a modern in-vessel composting and the resultant fertilizer can be used for in-house landscaping or sold as organic fertilizer as attractive prices.

Another plausible way of managing organic waste at the food manufacturing plant is to biologically degrade it in an anaerobic digester leading to the formation of energy-rich biogas and digestate. Biogas can be used as a heating fuel in the plant itself or converted into electricity by using a CHP unit while digestate can be used as a soil conditioner. Biogas can also be converted into biomethane or bio-CNG for its use as vehicle fuel.

Items such as cardboard, clean plastic, metal and paper are all commodities that can be sold to recyclers Lots of cardboard boxes are used by food manufacturers for supplies which can be broken down into flat pieces and sold to recyclers.

Cardboard boxes can also be reused to temporarily store chip packages before putting them into retail distribution boxes. Packaging can be separated in-house and recovered using “jet shredder” waste technologies which separate film, carton and foodstuffs, all of which can then be recycled separately.

Organizing a Zero-Landfill Program

How do you develop a plan to create a zero-landfill or zero waste program in food and beverage producing company? The best way to begin is to start at a small-level and doing what you can. Perfect those programs and set goals each year to improve. Creation of a core team is an essential step in order to explore different ways to reduce waste, energy and utilities.

Measuring different waste streams and setting a benchmark is the initial step in the zero-landfill program. Once the data has been collected, we should break these numbers down into categories, according to the EPA’s Food Recovery Challenge and identify the potential opportunities.

For example, inorganic materials can be categorized based on their end lives (reuse, recycle or landfill).  The food and beverage industry should perform a waste sort exercise (or dumpster dive) to identify its key streams.

Nestlé USA – A Case Study

In April 2015, Nestlé USA announced all 23 of its facilities were landfill free. As part of its sustainability effort, Nestlé USA is continually looking for new ways to reuse, recycle and recover energy, such as composting, recycling, energy production and the provision of safe products for animal feed, when disposing of manufacturing by-products.

Employees also work to minimize by-products and engage in recycling programs and partnerships with credible waste vendors that dispose of manufacturing by-products in line with Nestlé’s environmental sustainability guidelines and standards. All Nestlé facilities employ ISO 14001-certified environmental management systems to minimize their environmental impact.

Waste Management in Olive Oil Industry

olive-oil-wastesThe olive oil industry offers valuable opportunities to farmers in terms of seasonal employment as well as significant employment to the off-farm milling and processing industry.  While this industry has significant economic benefits in regards to profit and jobs; the downside is it leads to severe environmental harm and degradation. In 2012, an estimated 2,903,676 tons of olive oil was produced worldwide, the largest olive oil producers being Spain, Italy, and Greece followed by Turkey and Tunisia and to a lesser extent Portugal, Morocco and Algeria. Within the European Union’s olive sector alone, there are roughly 2.5 million producers, who make up roughly one-third of all EU farmers.

Types of Wastes

Currently, there are two processes that are used for the extraction of olive oil, the three-phase and the two-phase. Both systems generate large amounts of byproducts.  The two byproducts  produced by the three-phase system are a solid residue known as olive press cake (OPC) and large amounts of aqueous liquid known as olive-mill wastewater (OMW).  The three-phase process usually yields 20% olive oil, 30% OPC waste, and 50% OMW.  This equates to 80% more waste being produced than actual product.

Regardless of system used, the effluents produced from olive oil production exhibit highly phytotoxic and antimicrobial properties, mainly due to phenols.  Phenols are a poisonous caustic crystalline compound.  These effluents unless disposed of properly can result in serious environmental damage.  There is no general policy for waste management in the olive oil producing nations around the world.  This results in inconsistent monitoring and non-uniform application of guidelines across these regions.

State of Affairs

Around 30 million m3 of olive mill wastewater is produced annually in the Mediterranean area.  This wastewater cannot be sent to ordinary wastewater treatment systems, thus, safe disposal of this waste is of serious environmental concern.  Moreover, due to its complex compounds, olive processing waste (OPW) is not easily biodegradable and needs to be detoxified before it can properly be used in agricultural and other industrial processes.

This poses a serious problem when the sophisticated treatment and detoxification solutions needed are too expensive for developing countries in North Africa, such as Morocco, Algeria and Tunisia, where it is common for OMW to be dumped into rivers and lakes or used for farming irrigation.  This results in the contamination of ground water and eutrophication of lakes, rivers and canals.  Eutrophication results in reductions in aquatic plants, fish and other animal populations as it promotes excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of oxygen, causing aquatic populations to plummet.

Another common tactic for disposal of olive mill wastewater is to collect and retain it in large evaporation basins or ponds.  It is then dried to a semi-solid fraction. In less developed countries where olive processing wastes is disposed of, this waste, as well as olive processing cake and SOR waste is commonly unloaded and spread across the surrounding lands where it sits building up throughout the olive oil production season.  Over time these toxic compounds accumulate in the soil, saturating it, and are often transported by rain water to other nearby areas, causing serious hazardous runoff. Because these effluents are generally untreated it leads to land degradation, soil contamination as well as contamination of groundwater and of the water table itself.

Even a small quantity of olive wastewater in contact with groundwater has the potential to cause significant pollution to drinking water sources. The problem is more serious where chlorine is used to disinfect drinking water. Chlorine in contact with phenol reacts to form chlorophenol which is even more dangerous to human health than phenol alone.

Remedial Measures

The problems associated with olive processing wastes have been extensively studied for the past 50 years.  Unfortunately, research has continued to fall short on discovering a technologically feasible, economically viable, and socially acceptable solution to OPW.  The most common solutions to date have been strategies of detoxification, production system modification, and recycling and recovery of valuable components.  Because the latter results in reductions in the pollution and transformation of OPW into valuable products, it has gained popularity over the past decade. Weed control is a common example of reusing OPW; due to its plant inhibiting characteristics OPW once properly treated can be used as an alternative to chemical weed control.

Research has also been done on using the semisolid waste generated from olive oil production to absorb oil from hazardous oil spills.  Finally, in terms of health, studies are suggesting that due to OPW containing high amounts of phenolic compounds, which have high in antioxidant rates, OPW may be an affordable source of natural antioxidants. Still, none of these techniques on an individual basis solve the problem of disposal of OMW to a complete and exhaustive extent.

At the present state of olive mill wastewater treatment technology, industry has shown little interest in supporting any traditional process (physical, chemical, thermal or biological) on a wide scale.This is because of the high investment and operational costs, the short duration of the production period (3-5 months) and the small size of the olive mills.

Conclusion

Overall, the problems associated with olive processing wastes are further exemplified by lack of common policy among the olive oil producing regions, funding and infrastructure for proper treatment and disposal, and a general lack of education on the environmental and health effects caused by olive processing wastes.   While some progress has been made with regards to methods of treatment and detoxification of OPW there is still significant scope for further research.  Given the severity of environmental impact of olive processing wastes, it is imperative on policy-makers and industry leaders to undertake more concrete initiatives to develop a sustainable framework to tackle the problem of olive oil waste disposal.

Anaerobic Digestion of Tannery Wastes

The conventional leather tanning technology is highly polluting as it produces large amounts of organic and chemical pollutants. Wastes generated by tanneries pose a major challenge to the environment. Anaerobic digestion of tannery wastes is an attractive method to recover energy from tannery wastes.

According to conservative estimates, more than 600,000 tons per year of solid waste are generated worldwide by leather industry and approximately 40–50% of the hides are lost to shavings and trimmings. Everyday a huge quantity of solid waste, including trimmings of finished leather, shaving dusts, hair, fleshing, trimming of raw hides and skins, are being produced from the industries. Chromium, sulphur, oils and noxious gas (methane, ammonia, and hydrogen sulphide) are the elements of liquid, gas and solid waste of tannery industries.

Biogas from Tannery Wastes

Anaerobic digestion (or biomethanation) systems are mature and proven processes that have the potential to convert tannery wastes into energy efficiently, and achieve the goals of pollution prevention/reduction, elimination of uncontrolled methane emissions and odour, recovery of biomass energy potential as biogas, production of stabilized residue for use as low grade fertilizer.

Anaerobic digestion of tannery wastes is an attractive method to recover energy from tannery wastes. This method degrades a substantial part of the organic matter contained in the sludge and tannery solid wastes, generating valuable biogas, contributing to alleviate the environmental problem, giving time to set-up more sustainable treatment and disposal routes. Digested solid waste is biologically stabilized and can be reused in agriculture.

Until now, biogas generation from tannery wastewater was considered that the complexity of the waste water stream originating from tanneries in combination with the presence of chroming would result in the poisoning of the process in a high loaded anaerobic reactor.

When the locally available industrial wastewater treatment plant is not provided by anaerobic digester, a large scale digestion can be planned in regions accommodating a big cluster of tanneries, if there is enough waste to make the facility economically attractive.

In this circumstance, an anaerobic co-digestion plant based on sludge and tanneries may be a recommendable option, which reduces the quantity of landfilled waste and recovers its energy potential. It can also incorporate any other domestic, industrial or agricultural wastes. Chrome-free digested tannery sludge also has a definite value as a fertilizer based on its nutrient content.

Potential Applications of Biogas

Biogas produced in anaerobic digesters consists of methane (50%–80%), carbon dioxide (20%–50%), and trace levels of other gases such as hydrogen, carbon monoxide, nitrogen, oxygen, and hydrogen sulfide.  Biogas can be used for producing electricity and heat, as a natural gas substitute and also a transportation fuel. A combined heat and power plant (CHP) not only generates power but also produces heat for in-house requirements to maintain desired temperature level in the digester during cold season.

CHP systems cover a range of technologies but indicative energy outputs per m3 of biogas are approximately 1.7 kWh electricity and 2.5kWh heat. The combined production of electricity and heat is highly desirable because it displaces non-renewable energy demand elsewhere and therefore reduces the amount of carbon dioxide released into the atmosphere.

AD Plant at ECCO’s Tannery (Netherlands)

A highly advanced wastewater treatment plant and biogas system became fully operational in 2012 at ECCO’s tannery in the Netherlands. A large percentage of the waste is piped directly into the wastewater plant to be converted into biogas. This biogas digester provides a source of renewable fuel and also helps to dispose of waste materials by converting waste from both the leather-making processes, and the wastewater treatment plant, into biogas. All excess organic material from the hides is also converted into biogas.

This project enables ECCO Tannery to reduce waste and to substitute virtually all of its consumption of non-renewable natural gas with renewable biogas. The aim is to use more than 40% of the total tannery waste and replace up to 60% of the total natural gas consumption with biogas.

4 Reasons Why Inflatable Packer is a Must Have

Non-stop operating challenges in the field of the gas, oilfield, and underground mining has led the inflatable technology to become a mainstream go-to solution for those in jobs of high-pressure drilling, borehole measurement, and tunneling. And it is none other than the inflatable packers that have been extensively catering to the niche since a decade now. The best thing about these tools is that they easily pass through restrictions and they are extremely sturdy to stand all the extremities and challenges of their projects.

With these tools rapidly gaining the ground in almost all parts of boring, sealing and mechanical jobs, it’s probably time to take a look at what makes these testing powerhouses really an unmatched solution in the field of special civil engineering and geotechnical studies. There are a plenty of informative and reliable sources, including http://www.aardvarkpackers.com/products-list/inflatable-packers/ and others that can tell you how these tools work and benefit their users.

What is an Inflatable Packer

As the name suggests, an inflatable packer is a plug equipment that can be extended and used in a wide array of decommissioning projects more specialized in terms of hole temperature and washouts etc. These plugs are both robust and versatile in nature and can be deployed where activities like hydraulic fracturing and high-pressure permeability require an in-depth planning and execution.

It’s the pipe that makes the main body of the packer and its the outside of the pipe that can inflate multiple times its original diameter to offer the space needed for all conventional jobs like coil tubing, pumping injections, tubes, and more.

Types of Inflatable Packers

When you have a clear idea about the job, it will be easy to choose your kind of pick from a wide selection of packers. They are many types, though…

  1. Fixed end packers
  2. Single or sliding end packers available in three styles, non reinforced, partially reinforced or fully reinforced
  3. Steel fortified
  4. Wire-line packers
  5. Custom packers (metal or other combinations)

Remember, every job needs an inflatable tool that can serve the bespoke purpose.

Uses of Inflatable Packers

As already mentioned earlier, inflatable packers are used in a wide range of energy-optimized fields, including groundwater projects, dewatering, high-pressure mining, contamination, block caving, core drilling, rock blasting and other kinds of stress testing

However, below mentioned is a list of broad range applications where these inflated tools are hugely deployed…

  1. Multi-depth ground consolidation
  2. Unconsolidated material consolidation
  3. Solid rock consolidation
  4. Improvement of mechanical properties
  5. Underground soil injections
  6. Lifting injections
  7. Sealing projects
  8. Injections in foundations

So, now that you know about most of the high-key projects where packers are used, there are certain unique features that make a packer ideal for a job.

  1. Extension capability of the packer’s hose,
  2. High-pressure rating
  3. The interior measurement of the pipe
  4. The exterior measurement of the pipe
  5. Longness of the sealing section that complies with the uneven borehole

The real advantage of having an inflated tool with an increased number of features is that it will make sure you can use it in multifaceted projects.

Advantages of inflatable packers

There are four main reasons that make these tools a must-have. They are as follows:

  1. Inflatable packers are reusable

Yes, most of their parts can be used for a great number of times. All the parts from a mandrel, inflation point, rubber element to connectors are exchangeable and their models are available in different lengths.

  1. Material parts are built sturdy

A non-welded packer is made robust and its patented and reinforcing ribs offer a tighter grip in the target areas to withstand challenges and vulnerabilities during and post inflation. What’s more, the packer ensures a uniform inflation between its metal ribs to offer maximum efficiency at disposal operations.

  1. Good use in inconsistent contact pressure

The packer’s metal ribs offer reinforcing anchoring in the end subs. This allows the inflatable tool to optimize its pressure differential holding capacity in varying depths.

  1. Flawless and safe sealing

While the ribs and the high-quality threads of an inflatable packer offer a greater surface preparation, eliminating any need for using crossover sub, welding or epoxy, the larger expansion range of a packer’s valve system provides an extra room for the fluid and the sealing functions, What’s more, all its material tubes and check valves can be cleaned easily when you separate them.

But the benefits of using these tools don’t end just here. There are a tall-list of other advantages too when you buy a packer of this type.

Final Thoughts

In a nutshell, inflatable packers prove extremely efficient where a perfect decommissioning job can add hundreds of thousands of dollars to the ever-flourishing energy industry. Their proven track records make them a must-have for projects like test injections, geological boring, water pressure control and special cases like plugging and abandoning wells just to name a few. The good news is, nowadays these tools are made available just a click away. Just go through the specifications carefully and pick the one that best suits your niche.

Recycling of EPS Foam Packaging

Municipalities and organisations are facing a growing problem in disposal and recycling of EPS foam packaging and products. EPS foam (Encapsulated Poly-Styrene) packaging is a highly popular plastic packaging material which finds wide application in packaging of food items, electronic goods, electrical appliances, furniture etc due to its excellent insulating and protective properties. EPS foam (also known as polystyrene) is also used to make useful products such as disposable cups, trays, cutlery, cartons, cases etc. However, being large and bulky, polystyrene take up significant space in rubbish bins which means that bins becomes full more quickly and therefore needs to be emptied more often.

Polystyrene is lightweight compared to its volume so it occupies lots of precious landfill space and can be blown around and cause a nuisance in the surrounding areas. Although some companies have a recycling policy, most of the polystyrene still find its way into landfill sites around the world.

Environmental Hazards of EPS Foam

While it is estimated that EPS foam products accounts for less than 1% of the total weight of landfill materials, the fraction of landfill space it takes up is much higher considering that it is very lightweight.  Furthermore, it is essentially non-biodegradable, taking hundreds perhaps thousands of years to decompose.

Even when already disposed of in landfills, polystyrene can easily be carried by the wind and litter the streets or end up polluting water bodies. When EPS foam breaks apart, the small polystyrene components can be eaten by marine organisms which can cause choking or intestinal blockage.

Polystyrene can also be consumed by fishes once it breaks down in the ocean.  Marine animals higher up the food chain could eat the fishes that have consumed EPS, thus concentrating the contaminant.  It could be a potential health hazard for us humans who are on top of the food chain considering that styrene, the plastic monomer used in manufacturing EPS has been classified by the US National Institutes of Health (NIH) and the International Agency for Research on Cancer (IARC) as a possible human carcinogen.

Styrene is derived from either petroleum or natural gas, both of which are non-renewable and are rapidly being depleted, creating environmental sustainability problems for EPS.

Trends in EPS Foam Recycling

Although the Alliance of Foam Packaging Recyclers have reported that the recycling rate for post-consumer and post-commercial EPS in the United States have risen to 28% in 2010 from around 20% in 2008, this value is still lower than most solid wastes.  According to USEPA, auto batteries, steel cans and glass containers have recycle rates of 96.2%, 70.6% and 34.2% respectively.

Because it is bulky, EPS foam takes up storage space and costs more to transport and yet yields only a small amount of polystyrene for re-use or remolding (infact, polystyrene accounts for only 2% of the volume of uncompacted EPS foams). This provides little incentive for recyclers to consider EPS recycling.

Products that have been used to hold or store food should be thoroughly cleaned for hygienic reasons, thus compounding the costs.  For the same reasons, these products cannot be recycled to produce the same food containers but rather are used for non-food plastic products.  The manufacture of food containers, therefore, always requires new polystyrene.  At present, it is more economical to produce new EPS foam products than to recycle it, and manufacturers would rather have the higher quality of fresh polystyrene over the recycled one.

The cost of transporting bulky polystyrene waste discourages recyclers from recycling it.  Organizations that receive a large amount of EPS foam (especially in packaging) can invest in a compactor that will reduce the volume of the products. Recyclers will pay more for the compacted product so the investment can be recovered relatively easier.

There are also breakthroughs in studies concerning EPS recycling although most of these are still in the research or pilot stage.  Several studies have found that the bacteria Pseudomonas putida is able to convert polystyrene to a more biodegradable plastic.  The process of polystyrene depolymerization – converting polystyrene back to its styrene monomer – is also gaining ground.

Air Genius: An Indoor Air Quality Monitor With a Difference

Indoor Air Quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of building occupants. Understanding and controlling common pollutants indoors can help reduce your risk of indoor health concerns. Health effects from indoor air pollutants may be experienced soon after exposure or, possibly, years later.

Immediate Health Effects

Some health effects may show up shortly after a single exposure or repeated exposures to a pollutant. These include irritation of the eyes, nose, and throat, headaches, dizziness, and fatigue. Such immediate effects are usually short-term and treatable.

Sometimes the treatment is simply eliminating the person’s exposure to the source of the pollution, if it can be identified. Soon after exposure to some indoor air pollutants, symptoms of some diseases such as asthma may show up, be aggravated or worsened.

The likelihood of immediate reactions to indoor air pollutants depends on several factors including age and preexisting medical conditions. In some cases, whether a person reacts to a pollutant depends on individual sensitivity, which varies tremendously from person to person. Some people can become sensitized to biological or chemical pollutants after repeated or high level exposures.

In long-term effects, Other health effects may show up either years after exposure has occurred or only after long or repeated periods of exposure. These effects, which include some respiratory diseases, heart disease and cancer, can be severely debilitating or fatal. It is prudent to try to improve the indoor air quality in your home even if symptoms are not noticeable.

Factors Behind Poor IAQ

Gas and respirable particulates in the air are the primary sources that contribute to poor IAQ. Sources can include inadequate ventilation, poorly maintained HVAC systems, cooking stoves, non-vented gas heaters, tobacco smoke, vehicle exhaust emissions, building materials, carpeting, furniture, maintenance products, solvents, cleaning supplies etc.

The actual concentrations of these pollutants can also be amplified by other external factors including poor ventilation, humidity, and temperature.

Properties and Uses of POME

POMEPalm Oil processing gives rise to highly polluting waste-water, known as Palm Oil Mill Effluent (POME), which is often discarded in disposal ponds, resulting in the leaching of contaminants that pollute the groundwater and soil, and in the release of methane gas into the atmosphere. POME is an oily wastewater generated by palm oil processing mills and consists of various suspended components. This liquid waste combined with the wastes from steriliser condensate and cooling water is called palm oil mill effluent.

On average, for each ton of FFB (fresh fruit bunches) processed, a standard palm oil mill generate about 1 tonne of liquid waste with biochemical oxygen demand 27 kg, chemical oxygen demand 62 kg, suspended solids (SS) 35 kg and oil and grease 6 kg. POME has a very high BOD and COD, which is 100 times more than the municipal sewage.

POME is a non-toxic waste, as no chemical is added during the oil extraction process, but will pose environmental issues due to large oxygen depleting capability in aquatic system due to organic and nutrient contents. The high organic matter is due to the presence of different sugars such as arabinose, xylose, glucose, galactose and manose. The suspended solids in the POME are mainly oil-bearing cellulosic materials from the fruits. Since the POME is non-toxic as no chemical is added in the oil extraction process, it is a good source of nutrients for microorganisms.

Biogas Potential of POME

POME is always regarded as a highly polluting wastewater generated from palm oil mills. However, reutilization of POME to generate renewable energies in commercial scale has great potential. Anaerobic digestion is widely adopted in the industry as a primary treatment for POME. Biogas is produced in the process in the amount of 20 mper ton FFB. This effluent could be used for biogas production through anaerobic digestion. At many palm oil mills this process is already in place to meet water quality standards for industrial effluent. The gas, however, is flared off.

Palm oil mills, being one of the largest industries in Malaysia and Indonesia, effluents from these mills can be anaerobically converted into biogas which in turn can be used to generate power through CHP systems such as gas turbines or gas-fired engines. A cost effective way to recover biogas from POME is to replace the existing ponding/lagoon system with a closed digester system which can be achieved by installing floating plastic membranes on the open ponds.

As per conservative estimates, potential POME produced from all Palm Oil Mills in Indonesia and Malaysia is more than 50 million m3 each year which is equivalent to power generation capacity of more than 800 GW.

New Trends

Recovery of organic-based product is a new approach in managing POME which is aimed at getting by-products such as volatile fatty acid, biogas and poly-hydroxyalkanoates to promote sustainability of the palm oil industry.  It is envisaged that POME can be sustainably reused as a fermentation substrate in production of various metabolites through biotechnological advances. In addition, POME consists of high organic acids and is suitable to be used as a carbon source.

POME has emerged as an alternative option as a chemical remediation to grow microalgae for biomass production and simultaneously act as part of wastewater treatment process. POME contains hemicelluloses and lignocelluloses material (complex carbohydrate polymers) which result in high COD value (15,000–100,000 mg/L).

POME-Biogas

Utilizing POME as nutrients source to culture microalgae is not a new scenario, especially in Malaysia. Most palm oil millers favor the culture of microalgae as a tertiary treatment before POME is discharged due to practically low cost and high efficiency. Therefore, most of the nutrients such as nitrate and ortho-phosphate that are not removed during anaerobic digestion will be further treated in a microalgae pond. Consequently, the cultured microalgae will be used as a diet supplement for live feed culture.

In recent years, POME is also gaining prominence as a feedstock for biodiesel production, especially in the European Union. The use of POME as a feedstock in biodiesel plants requires that the plant has an esterification unit in the back-end to prepare the feedstock and to breakdown the FFA. In recent years, biomethane production from POME is also getting traction in Indonesia and Malaysia.
