Guide to Effective Waste Management

waste-mountainThe best way of dealing with waste, both economically and environmentally, is to avoid creating it in the first place. For effective waste management, waste minimization, reuse, recycle and energy recovery are more sustainable than conventional landfill or dumpsite disposal technique.

Waste Minimization

Waste minimization is the process of reducing the amount of waste produced by a person or a society. Waste minimization is about the way in which the products and services we all rely on are designed, made, bought and sold, used, consumed and disposed of.

Waste Reuse

Reuse means using an item more than once. This includes conventional reuse where the item is used again for the same function and new-life reuse where it is used for a new function. For example, concrete  is a type of construction waste which can be recycled and used as a base for roads; inert material may be used as a layer that covers the dumped waste on landfill at the end of the day.

Waste Recycling

Recycling of waste involves reprocessing the particular waste materials so that it can be used as raw materials in another process. This is also known as material recovery. A well-known process for recycling waste is composting, where biodegradable wastes are biologically decomposed leading to the formation of nutrient-rich compost.

Waste-to-Energy

As far as waste-to-energy is concerned, major processes involved are mass-burn incineration, RDF incineration, anaerobic digestion, gasification and pyrolysis. Gasification and pyrolysis involves super-heating of municipal solid waste in an oxygen-controlled environment to avoid combustion. The primary differences among them relate to heat source, oxygen level, and temperature, from as low as about 300°C for pyrolysis to as high as 11 000°C for plasma gasification. The residual gases like carbon dioxide, hydrogen, methane etc are released after a sophisticated gas cleaning mechanism.

MSW incineration produce significant amounts of a waste called bottom ash, of which about 40% must be landfilled. The remaining 60% can be further treated to separate metals, which are sold, from inert materials, which are often used as road base.

The above mentioned techniques are trending in many countries and region. As of 2014, Tokyo (Japan) has nineteen advanced and sophisticated waste incinerator plants making it one of the cleanest cities. From the legislature standpoint, the country has implemented strict emission parameters in incinerator plants and waste transportation.

The European Union also has a similar legislature framework as they too faced similar challenges with regards to waste management. Some of these policies include – maximizing recycling and re-use, reducing landfill, ensuring the guidelines are followed by the member states.

Singapore has also turned to converting household waste into clean fuel, which both reduced the volume going into landfills and produced electricity. Now its four waste-to-energy plants account for almost 3% of the country’s electricity needs, and recycling rates are at an all-time high of 60%. By comparison, the U.S. sent 53% of its solid waste to landfills in 2013, recycled only 34% of waste and converted 13% into electricity, according to the US Environmental Protection Agency.

Trends in Waste Collection

Since the municipal solid waste can be a mixture of all possible wastes and not just ones belonging to the same category and recommended process, recent advances in physical processes, sensors, and actuators used as well as control and autonomy related issues in the area of automated sorting and recycling of source-separated municipal solid waste.

Automated vacuum waste collection systems that are located underground are also actively used in various parts of the world like Abu Dhabi, Barcelona, Leon, Mecca and New York etc. The utilization of the subsurface space can provide the setting for the development of infrastructure which is capable of addressing in a more efficient manner the limitations of existing waste management schemes.

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

This technique also minimizes operational costs, noise and provides more flexibility. There are various new innovations like IoT-enabled garbage cans, electric garbage trucks, waste sorting robots and mechanisms etc are also being developed and deployed at various sites.

Conclusion

Waste management is a huge and ever growing industry that has to be analyzed and updated at every point based on the new emergence of threats and technology. With government educating the normal people and creating awareness among different sector of the society, setting sufficient budgets and assisting companies and facilities for planning, research and waste management processes  can help to relax the issues to an extent if not eradicating it completely. These actions not only help in protecting environment, but also help in employment generation and boosting up the economy.

The Impact of Smart Homes on Generations

America is already feeling the impact of smart homes. A large industry based on this technology is forming. But, what is the effect of it on the different generations? Here you can find a brief discussion of the impact of smart homes on generations.

What is a Smart Home?

Smart homes consist of all the different smart products owned by the user. These products are interconnected. It makes use of the internet to connect to other products. This technical feature is called the Internet of Things (IoT).

There are all kinds of products. Every room or space in a home can be automated by smart home products. You can even install smart devices into your backyard like smart lawnmowers and irrigation systems.

Benefits for all generations

Smart home products are designed to benefit its users. The technology is developed for all generations. So there are benefits to its use that applies to everyone.

These benefits include:

  • An increase in comfort of the user’s lifestyle.
  • Increased life expectancy caused by the usage of these products (i.e. smart security products).

Impacts on different generations

Three larger generation groups have been defined for the purpose of this discussion. It’s been split into the retirees, the working force, and the youth.

Retirees

Smart home products can connect to all kinds of services and devices. Elderly people can enjoy minor medical check-ups from the comfort of their homes. Video calls and domestic smart medical equipment can supply all the information a doctor needs. Doctors can keep an eye on patients that are too far from their offices.

Retired people can make use of smart home technology to automate simple tasks. Grocery shopping and other basic services are accessible through these products. Retirees will enjoy the improved elderly care and greater access to basic services caused by smart homes.

The working force

Smart home products like smart thermostats have been known to save its users an average of 20% in yearly warming and cooling costs. According to a study conducted by SafeAtLast, 57% of American smart home owners save about 30 minutes per day. Automating your home will save you lots of time and effort in the process.

The working force who owns smart home products will be more productive. They will also have more cash on hand due to extra savings. Smart homes can help to create a wealthier economy by assisting the working force.

The youth

The youth of today is the promise for tomorrow. Smart home technology is indirectly designed to increase the life expectancy of its user. All these benefits will help to cultivate a better tomorrow. The youth who grow up with smart home technology will have an advantage over their lesser privileged youths. Though, the psychological effects of this technology (over the long term) is yet to be studied.

Conclusion

This technology wants to make your life better. It will benefit every generation. Give it a try to experience the benefits yourself. Read on to for interesting facts on smart homes.
