What is Food Waste?
Have you ever thrown away your favorite meals because they have been sitting in your fridge for too long? Have you regretted buying bulks of food you and your family could not finish and ended up in the bins? The RTS Food waste in America in 2020 states that 40% of the US food supply, about 11 billion USD of food which is $1600 worth of produce per family is wasted.
Food waste is different from food loss; food loss is where food that has not been in the hands of the consumer is being wasted. On the other hand, food waste is food that has been bought by consumers that is usually thrown away usually due to excessive buying, going past expiry dates, misunderstanding of labels, and excessive cooking.
While there is food being wasted daily, 1 out of 8 people in America do not have enough food to eat. To add on, more people lack food to eat especially with the COVID-19 situation, when there is decreasing rates of employment and financial instability.
So, where does all our food waste go?
Food waste and Landfill
In the United States, it is estimated 35.3 million tons of food went to landfills in 2018 and 24.1% of the landfills are food waste. That is equivalent to 30-40% of the food supply and ⅓ of food produced is being wasted. This added up to approximately 1.3 billion tons and $400 billion USD worth of food in 2021.
Landfills are a system of waste management, where an empty low lying land is filled with waste and is sometimes covered by sand to create flat land. These landfills are usually managed, to ensure their safety for the surrounding environment but their long term effects can be dangerous to the Earth and humans. Food that is being left in the landfill produces methane, which causes harm for our environment as greenhouse gas. Methane (CH4) can hold 25 times more heat than carbon dioxide (CO2) which contributes to global warming. This happens because food waste in landfills usually does not decompose like they do when we compost them naturally or with a composer. To compose properly, the materials need oxygen to produce less methane and more carbon dioxide. Landfills do not allow oxygen to enter the process as sand or more waste blocks all air flow. This means that there is not enough oxygen for composting to occur, as result, producing more methane than the normal composting process. Food waste in landfills can be more harmful to the environment as it produces more Methane than composting at home, which can generate a hotter atmosphere, which can lead to climate change and global warming.

Ways to Prevent Food Waste ending up in Landfills
Food waste not only is wasteful, but food waste in landfill can exemplify the negative impact of food waste. So how can we individually ensure reduction of food waste?
Plan your Grocery List
Prepare ahead and know what is inside your fridge. Make a list of things you will be needing for the week or days to cook, and the amount of each item you will be needing. While it may be cheaper to buy in bulks, be extra careful to ensure you are able to consume the item within a given time frame. Instead, buy smaller quantities of things you will definitely be using for the week to reduce food waste weekly
Eat before you go shopping
People tend to buy more when they are hungry during shopping as their hunger desires create temptations to buy more than needed to satisfy their hunger.

Create one day where there is no menu for the meal but to use what is available in the kitchen instead of getting more Make a zero waste menu, challenge new recipes, and add, subtract and replace ingredients with the leftovers from the week.

There are different Food Product Dates on food we buy in stores and markets. The common ones we see are “sell-by,” “use-by,” “best-by,” and expiration dates. Here’s a guide by Food Safety and Inspection that you can follow to understand each of these labels.
- “A “Best if Used By/Before” date indicates when a product will be of the best flavor or quality. It is not a purchase or safety date.
- A “Sell-By” date tells the store how long to display the product for sale for inventory management. It is not a safe date.
- A “Use-By” date is the last date recommended for the use of the product while at peak quality. It is not a safety date except for when used on infant formula as described below.
- A “Freeze-By” date indicates when a product should be frozen to maintain peak quality. It is not a purchase or safety date.
Prepare and Store Single Serve
Once bought, try to preserve them by freezing, cutting, cooking before storing them in the fridge. Prepare them single serving to reduce the time cooking and actually use the products. You could also cook the items you bought into stocks, soups, dishes, smoothies to make them into easy access meals.
Compose at Home Not Landfill

Materials Needed to Compost at Home
