Food Waste management in the U.S.

Posted on by

Food waste is a massive problem in the United States.  Currently, a large portion of food is wasted in the United States and this wasted food ends up in various places.  These charts document the pathways in where wasted food ends up after it goes unused in 2018.  The column chart on the left depicts the weight in US tons of wasted food and approximately how many tons of wasted food end up in each place.  As you can see, the largest number of wasted food ends up in landfills with 35,277,543 tons of wasted food managed by landfills.  This massive number dwarfs any other pathway for wasted food.  For instance, wasted food used on land application is only 259,448.  The amount of wasted food that ends up in landfills is 135.97 times greater than the amount of wasted food used for land application.  The pie chart on the left details the same numbers however this chart gives the percentages of where wasted food ends up. As you can see more clearly, all other pathways for wasted food combined are less than the percentage of wasted food that goes to landfills.  In 2018, 55.9% of all wasted food was sent to landfills and not used in any other constructive way.  Out of the 63,132,123 tons of food wasted in 2018, 35,277,543 tons of that food ended up in landfills.  Not only is it horribly unsustainable to waste  food, but the methods in which wasted food is used afterwards is even more unsustainable and is contributing to the problems that we are seeing today.

Recycling and composting trends (1960-2018)

Posted on by

I complied a bar graph that showed the percentage increase in the number of different materials that was increased from 1960 on. This shows that through the years the amount of things recycled has increased along with having more things being able to be recycled. This could be caused by the increase in education and the advancements in technology.

Single Use Plastic Bottles per Week

Posted on by

Single use plastic water bottles are very bad for the environment, typically because they are not recycled and are often thrown out. The plastic takes centuries to full decay and as plastic decays it leaks dangerous chemicals into the groundwater and soil. Even if plastic is recycled, it might not be recycled properly and would still need to decay on the earth. The total carbon footprint of one plastic water bottle is about 828 grams of carbon dioxide. Lots of college students use single use plastic bottles for water, coffee or any other drink. These cups are typically thrown away, adding to the amount of plastic waste in the world. This chart shows that the average number of single use plastic bottles per week is 3.9 amongst the sample size that I gathered data from. The lowest number per week was 0, due to my friend’s constant usage of a reusable water bottle and the highest number was 9. That means per week a college aged student similar to my friends would use 3.9 single use bottles adding up to a 3229.2 grams of carbon dioxide per week released due to this plastic waste.

CO2 Emissions by Country

Posted on by

Of course we know now that emissions of carbon dioxide are incredibly harmful to our earth and the ozone. As one of the most prominent and dangerous green house gasses, limiting carbon dioxide emissions is crucial to saving our planet before it heats up to a point of no return. The graph that I am going to conduct is relatively simple but it will be stats on some of the largest and most industrialized countries in the world and the numbers that relate to their C02 emissions.

 

 

These ten countries make up nearly 70% of the worlds CO2 emissions and of these 10 countries, China make sup 43.6% of the emissions. These countries are all very industrialized and have shown large jumps in population growth. If that growth continues, some policies have to implemented to lower these emissions!

Shower Length and Water Waste

Posted on by

An issue that directly connects to sustainability is water waste. The way I aim to measure water waste in daily life is through how long it takes my friends to shower. Showering is one of the easiest ways to waste large quantities of water because of the constantly flowing stream of water. I asked many of my friends how long on average that they shower for in order to evaluate how much water they waste. Based on their answers and the data I gathered, my friends spend on average 21.8 minutes in the shower. The shortest time recorded is 5 minutes and the longest time is on average 45 minutes. The average flow rate of a shower head is 2.1 gallons per minute. This indicates that on average my friends waste 45.78 gallons of water per shower. My friends that take showers on the longer side, 30-45 mins can take shorter showers to reduce their personal water waste and become more sustainable. Every minute makes a difference and adds up over time.

Gasoline prices and population in New York City Boroughs

Gasoline prices per borough

This graph displays the gas prices in 3 boroughs in New York city per gallon.  All three boroughs have a similar range but the trend shows that Bronx has the highest price in gas despite having the lowest population. The effect of having to pay more for gasoline despite being the lowest populated. support the idea that both boroughs nearby spend less money on gas therefore may be marginally richer to spend on other things.

Gallons of Water Wasted Per Day

Posted on by

For this week’s bog topic, I thought it’d be interesting to reach out to my friends and see how many gallons of water that they believe that they waste a day. Water waste is a huge issue when it comes to sustainability across the globe. Water can be wasted in many different ways and I feel that is often over looked. For example, keeping the water running when you brush your teeth, taking too long of showers, pouring out drinking water, etc. After reaching out to 10 of my friends, I put the data into a bar graph, which is pasted below;

The range of answers is quite obvious as one of my friend’s stated that she doesn’t waste any water, meanwhile, another one of my friend’s claimed that she wastes 20 gallons of water a day. By asking my friends this question, it was intended to make them think of all of the ways that they waste water and in return think of the ways that they can reduce water waste. Making these small changes can have a big impact on our globe.

Weekly Seatbelt Time

Posted on by

This week I decided to involve some of my friends in an investigation into roughly how long Union students spend in a car weekly. I decided to ask the simple question, “How long, roughly, do you think you spend in a car per week?” and recorded the responses I received. The data represents the amount of minutes a handful of Union students spend weekly in a car. The data reflects 50% of those interviewed spend 30 minutes or less in a car weekly and 50% spend more than 30 minutes in a car weekly. I was pleasantly surprised to find that all individuals I interviewed spent under an hour in a car on-average, which is limiting their carbon footprint on the environment when they are at school. The data is possibly a reflection of the small size of Union contributing to students choosing to walk distances instead of driving them. The warmer weather we are experiencing may also be contributing to this data.

Single-use Plastics at Union

Posted on by

 

This graph shows the average amount of declining these individuals spend at Union per week. Declining is used outside of the dining halls therefore every item is individually wrapped or bottled. There are no reusable dishes or cutlery. Hence the more declining spent per week, the more single-use plastics and waste there is. From this bar chart, we can infer that Zac uses and wastes the most single-use plastics.
