What is the good life? Per the definition of the Greek philosophers, it is not having a great time, drinking, flirting and surfing online. Read the great work of Aristotle for a reminder about what Greek Philosophy is all about. It is having a life that is good because it adds good value to human kind. Thinking and talking about virtue are some of the best things that a person can do with his life according to them. It does not mean having a life centered on shallow pleasures like online chatting and speculative investments, partying and drinking until the early hours of the morning, eating for greed and not hunger. Greek philosophers may not have been ready to deal with modern life as we know it but their thinking still applies. It can be harder to have a good life now than it was in their time, as young people are constantly bombarded with entertainment, advertisement and peer pressure from texting or the Web, that it may be hard for them not to succumb to the temptation from the sight of college dropouts who made millions of dollars starting their ecommerce website or other vain celebrities. Very few will win such a lottery ticket, plus the fame, television appearances and glory, as the famous people do. And women are easily attracted to them given their wealth and celebrity status. So does he live the good life? Not in the sense intended by the philosophers. The pursuit of wealth from card games is a totally wasteful activity that does not let him focus his mind on what is really important to consider as a human being: seeking order and beauty in the universe. Talking about beauty and cleanliness, we are very concerned with climate change, global warming and pollution here are teenpodcasters. With our friends at Fresno Dumpster Rental, we would like to start a podcast about waste management in the USA and how we can help limiting the number of landfills and unnecessary junk and waste created by human beings. According to experts, the real estate market in the United States has started a booming trend and this is why it is more important than ever to make sure our cities remain clean. Uncontrolled growth is what leads to the environmental crisis we are facing now and it is time people take their destiny in their own hands.

The year 2019 was marked by somewhat disconcerting environmental news: the re-shipment by some countries of South Asia of several tonnes of waste from the rich countries of the North. Ecological awareness or diplomatic rebellion, what can we learn from these trash container shipments by Asian countries? Everyone wants to save the planet but nobody wants to take the garbage out, and any waste management company knows the high cost of junk removal. Terrible dilemma, for a nation to have to collect, sort and recycle polluting waste and at the same time wear the cap of the green policeman concerned about the environment. All countries are struggling to recycle their waste. Plastic waste produced in the West ends up either at the landfill or in an incineration plant. But the poor quality products are sent to less visible countries. Concretely, Western countries do not hesitate to send bulky waste that they do not know how to treat to countries whose regulations on waste treatment are more permissive and this, at lower cost, with all the health risks that implies for workers and local populations. Among the “trash” countries, China has long been one of the most important recyclers of waste on the planet, especially plastic. This ostrich policy did not worry many people until 2018, when Beijing said stop to recycling plastic waste. The National Sword plan has been decreed by the Chinese government to denounce the accumulation of dirty and dangerous waste sent by the countries of the northern hemisphere, repeatedly flouting international regulations. This measure caused an unanticipated mess on the world waste market, forcing Western countries to redirect tonnes of non-compliant waste to countries in Southeast Asia. Faced with the profusion of litter, parallel channels have been developing. The importation of waste causes an indissoluble impact on the environment such as the creation of unauthorized dumping, or even mafia networks, which harm tourism, the main economic activity of these countries. Awareness or diplomatic rebellion, several countries in Southeast Asia have indicated that they no longer wish to be the dumping ground for our industrialized countries. This is how several hundred waste containers have been returned in recent years to their shippers.

In fact, the figures reflect the influence of water content on the limiting factor of the biological activity of the landfill, namely the degradation of cellulose. Indeed, this carbohydrate polymer, present in household waste at nearly 40% by weight, is the most important organic substrate but also the most difficult to biodegrade. Its degradation, which is incomplete (around 71 to 77%), is considered linear as a function of time with, it should be remembered, a half-life period estimated at fifteen years. It would contribute 90% of the total methane produced in the landfill.

In other words, cellulose would be almost the only carbon source used by microorganisms during the phase of stable and generalized methanogenesis, that is to say the longest phase of the life of the landfill, i.e. from 25 to 50 years or more when conditions are unfavourable, i.e. humidity within the waste below the 30 to 50% commonly recorded in landfills in temperate countries.

Associated with biodegradation, the loss of material in the leachates and the biogas produced leads to a reorganization of the materials still in place. A certain settling follows which is another direct indicator of the rate of degradation. A total theoretical complete settlement of 40% (compared to the initial height) is probable under optimal waste management methanogenesis conditions.

In practice, according to people who did get a dumpster in San Jose and other locations in California in order to avoid a trip to the dump, an average compaction of 30 to 35% is observed in landfill. Consequently, at the scale of the waste mass, the average moisture content, the cellulose content and the evolution of settlement are data that will make it possible to estimate the production of biogas, the life of the landfill or again the characteristic composition of leachates. From these data, obtained by analyzing the rock mass and solid, liquid and gaseous samples from the landfill, it is possible to define different modeling parameters of the landfill bioreactor.

The modeling must not only provide information on the general physiological state of the landfill but also allow the evolution of the landfill to be characterized over time, in particular its future impact on the environment. This is essential:
• control of the toxicity of gaseous and liquid effluents,
• the installation of leachate treatment units,
• biogas recovery and recovery projects,
• development and rehabilitation of the site.
