Due to the profound environmental impacts of food waste, a reduction in the amount disposed is necessary to create a more sustainable environment, and humans have a responsibility to protect the planet, even if it requires drastic changes to the current food system. Dr. M. Sanjayan of the University of California states that food waste is not purposeful, and proposes that it is perhaps subliminal. Over time, there have been significant changes in the amounts of food people are purchasing. Sanjayan states that this is due to the increase in the size of the dinner plate and the refrigerator, which have grown by 36% and 15% respectively since the 1960s due to the
Methanogens can produce methane using different organic and inorganic compounds such as carbon dioxide, acetate etc. Methanogens can also utilize the waste products of different bacteria to produce methane. Methane production can be used by the Methane production is a very versatile process which can utilize various
Hazardous waste is the most difficult waste to be managed, since in the treatment process, heavy metal and dioxin among others are obtained. The outcome elements are dangerous not only for the environment but also for public health. The fundamental rule in managing waste is given by the following hierarchy: prevention, reducing its production, reuse, recycles valuation and deposition. (Couto, Silva, Monteiro, & Rouboa, 2013). The impact of hazardous waste on the environment and health If waste is not well-managed, unpredictable negative outcomes of household hazardous waste can occur at its source (residential households), waste collection points, during transportation, and after deposit in landfills and/or incineration sites, with the potential to cause permanent damage to the environment and public health.
This program includes efforts such as waste collection, transportation and storage and safe disposal of waste. Procurement of recycled content supplies and equipment and education are also part of solid waste management. As compared to high income countries, municipalities in low and middle income countries allocate the majority of their solid waste management budget to collection and transportation services to a certain fractional population and final disposal costs are minimal because disposal is usually accomplished through open dumping (Tsega, 2013). Guerrero et al. (2013) added that most are poorly rendered services by municipal authorities as the systems applied are unscientific, out-dated and in-efficient and government policies on the environment are piecemeal where they exist and are poorly implemented.
Methane is a far more active greenhouse gas than carbon dioxide, but also one which is much less abundant in the atmosphere .Nitrous oxide, a powerful greenhouse production by soil cultivation practices, especially the use of commercial and organic fertilisers, fossil fuel combustion, nitric acid production, and biomass burning. Chlorofluorocarbons(CFCs). Synthetic compounds entirely of industrial origin used in a number of applications but now largely regulated in production and
Waste is produced by all sectors of the economy. Every person is a potential producer of waste. It is as old as the existence of human beings. In early times, in order to minimize the health impacts of wastes, transporting the waste out of residential places been the primary concern of authorities. After the end of Second World War a high rate of population and urbanization has brought an increased demand of urban and waste disposal land.
Waste management has been the center of discussion in various international and national meetings. Organizations based on environmental conservation have also come up in large numbers, creating awareness on the effects of waste paper and how to deal with the challenge. Such organizations have largely contributed to the current trend, which involves sustainability in the pulp and paper industry (Rao
Sometimes, doctors use contaminated equipment, so patients are infected by dangerous pathogens. In addition, the lack of economic resources and the current government’s mismanagement are some of the reasons why this problem still exists today. Medical waste has harmful consequences. The main effect of this problem is the contagion of different infectious diseases. Many people can get poisoned or injured as a result of hygiene issues.
Abstract: How can we make the environment less harmful and minimize the waste into something more useful to us and avoid causing any bad things? Waste management is basically the solution. Waste management is managing the wastes from the beginning until the disposal. The three famous R’s in the environment which are Reduce Reuse Recycle, are the main things that will help in leading to a cleaner and better environment. The three of them are important; for each one of them is related to the other somehow.
