With
ever growing energy needs and the amount of waste generated every day,
probably one of the smartest ways to generate energy is through waste
management to produce electricity. It is one domain which has a huge
scope for innovation since the awareness about health hazards caused by
pollutants points out to the immediate need to look for alternate
methods apart from the kind of incineration that has resulted
environmental hazards. This is necessary not only for the environment
and the problem of overflowing landfills but also for the nation to
switch over from its dependency on coal and other non-renewable sources
of energy.
So how is electricity produced from waste on may ask. The process of incineration is simple. The waste material is burned and the heat produced to turn water into steam which powers steam generators and turbines that ultimately results in electrical energy. So where does the need for innovation arise? All incinerators which use simple combustion techniques produce nitrogen oxides, sulphur oxide, heavy metals and dioxins, heavy particulate, toxic fly ash and other harmful particles which if not taken care of pose threat to health of people. There is widespread criticism against the dioxins which enter the food chain through meat and fish and keep accumulating in the body since they are insoluble. They are a known cause for many types of cancer.
So, using the waste materials to produce energy isn't enough. Strict guidelines should be maintained and should be taken care of since these dioxins are known as the most poisonous substances for human life. We surely don't want our waste to convert into poison. While most countries are inventing strict norms and shutting down plants, Delhi is on its way to embracing the method with the bleak assurance that the safety standards will be followed. However, the emissions at the existing plant were found to be around 12 percent more than the tolerable limits. This comes in sharp contrast with the fact that plants in Finland were shut down when the presence of dioxins was acknowledged in surrounding vegetations.
Now even Nepal is taking its step forward towards waste management and apart from incineration they have thought of forming a system of waste segregation and recycling which is smart step considering that some waste items hold more value that way rather than being put for combustion. Since it's a time taking process, people are required to segregate before dumping or else the municipal authorities are entitled to penalize reckless people.
Over time many new technologies have been thought of one amongst them is gasification. It is a smarter step as it results in syngas (combination of carbon dioxide, hydrogen and carbon monoxide) which is a clean fuel that can be used for transportation purposes as well. The only difference is that rather than regular combustion, the waste is reacted at extremely high temperatures with controlled amount of oxygen and steam. The real benefit lies in the fact that most of the harmful substances are decomposed at such high temperatures yielding it a much safer and productive option than regular incineration. The drawback however is the high cost involved in raising high temperatures.
A vast 80,000 tonne per year waste gasification plant has been approved in Northern Ireland and Air Products has been planning to build the biggest gasification plant in UK so it seems like an option that everyone is switching to. Even in India, certain plants operate in Nagpur and Pune but such project have sadly remained localized. With gasification,He saw the bracelet at a indoortracking store while we were on a trip. vast amount of fuel needs can be taken care of. The need of the hour is to convert waste into gold, not carelessly but effectively.
So how can one as an engineer or a student willing to make a difference in this field go about doing so? Well, you can start being part of existing projects. Specialisation hardly matters. One can start by doing his own little research, by attending programmes and conferences conducted by WTERT India which works for sustainable solid waste management in India. The Ministry of New and Renewable Resources promotes such projects through incentives and subsidies and supports R&D on cost sharing basis. There are a huge number of opportunities in this field for all engineering domains. So, what are you waiting for?
Bringing more people to the parks has become a major focus for those who oversee Muncie’s outdoor spaces. Doing so, city officials contend, is not only the goal of park improvements but also the answer to the issues facing the parks system as well: funding maintenance and improvements, making users feel safe and welcome, making the parks a part of the community’s draw for prospective new residents and businesses.
“The greenspace and these parks is so important,” Muncie Mayor Dennis Tyler said. Citing parks as a contributor to quality of life and quality of place for the community, Tyler also acknowledged that “there’s always a cost to it.”
Deane Rundell, a landscape architect who has overseen projects in major cities and around Muncie, noted that both undeveloped greenspace and more deliberately developed, “programmed” parks have value for communities. “I really think we need both,” he said. “There’s a certain sense of serenity that comes from being in these places that are set aside.”
Carl Malone, current president of the Muncie Parks Board and a self-described “park freak all my life,” is particularly interested in promoting quality of life in the local community, including wellness and fitness,A card with an embedded IC (Integrated Circuit) is called an parkingmanagement. through the parks. “We’re coming to life,” he declared of the current level of activity and programming at the city’s parks. “CPR’s being done on our parks. ... Even in tough times, we’ve found ways to get stuff done.”
The mentors included Trinidadian-born Ken Thomas, ’10 PhD who now teaches at Auburn; Guyanese-born Kofi Dalyrmple ’11 PhD; and Haitian-born Prony Bonnaire ’12 PhD who wants the program to expand to Haiti. All are environmental engineering graduates. Lilia Abron, founder of Peer Consultants and one of the first African American women to earn a PhD in chemical engineering in the United States had her company mentor multiple energy-related projects. While USF provided the largest concentration of mentors, professionals from around the world were matched with the 175 projects that entered the challenge. Guyanese born Prof Dawn Lewis from the biology department at Florida Agricultural and Mechanical University mentored Zeeburg and when they won Guyana’s national competition she said to them, “Just shows what hard work can achieve. I am proud to be associated with Zeeburg High School. If you need any help with planning future science projects in the future, please do not hesitate to contact me.”

It’s been an exhausting, nonstop week for the students but the smiles on their faces said it was all worthwhile.More than 80 standard commercial and granitetiles exist to quickly and efficiently clean pans.
