Meals Ready to Eat (MREs) are a staple of military life, but they are also gaining popularity among adventure travellers and campers. MREs are typically packaged in plastic bags, and with millions of MREs being consumed annually, this results in the generation of thousands of tons of plastic waste. So, are MRE plastic bags recyclable?
| Characteristics | Values |
|---|---|
| Recyclability | While almost all plastic can theoretically be recycled, MREs are packaged in plastic pouches that may not be accepted by local recycling centers due to the multiple types of plastic and layers that are difficult to separate. |
| Environmental Impact | MREs generate thousands of tons of residual polymeric packaging waste annually, which can be left in the environment, recycled, or incinerated at a high cost. |
| Shelf Life | The shelf life of an MRE depends on the storage temperature. For example, an MRE stored at 100 degrees Fahrenheit will last a few months, while one stored at room temperature will last three years. |
| Packaging Material | MREs are packaged in flexible cans made of thick aluminum foil and plastic layers, known as tri-laminate retort pouches. |
| Plastic Types | The outer bag of an MRE is typically made of linear low-density polyethylene (LLDPE) and low-density polyethylene (LDPE). |
| Heat Resistance | The MRE bag material has an extended melt transition, with multiple thermal peaks observed over temperatures ranging from 100°C to 125°C. |

What You'll Learn
MRE bags are recyclable
MRE bags, or Meal, Ready-to-Eat packages, are primarily made of plastic. They are self-contained, individual field ration packs used by military personnel, outdoor adventurers, and emergency personnel. MREs were first introduced for use in the US military in 1981 and have since undergone several design updates.
The original MRE bag was a simple brown bag, which has since undergone two major and several minor updates. The bag is now a three-layer laminate pouch made of thick aluminium foil and plastic layers. The aluminium foil and plastic layers are essential in the canning process, which is a common food preservation technology. The food is boiled in the can to kill all bacteria and then sealed to prevent any new bacteria from entering. This process ensures the food does not spoil until the can is opened.
The plastic packaging of MREs has raised concerns about its environmental impact and recyclability. While in theory, almost all plastic can be recycled, various barriers exist in practice, including economic and technical challenges, especially when dealing with multiple types of plastic and layers that are difficult to separate.
However, advancements in distributed recycling technologies now allow for on-demand reconstitution of MRE pouch waste into useful appliances via material extrusion additive manufacturing. Recycling of MRE pouch materials through a combined compounding, filament extrusion, and fused filament fabrication (FFF) additive manufacturing protocol has been demonstrated. This recycling process has multiple benefits, and the mechanical properties and barrier properties of the additively manufactured structures were found to be comparable to the native pouch materials.
Therefore, while the recyclability of MRE bags depends on the material they are made from and the capabilities of the local waste disposal center, advancements in technology have made it possible to recycle MRE bags and reduce their environmental impact.

MRE packaging generates waste
The MRE package is a three-layer laminate pouch made of thick aluminium foil and plastic layers. The outer bag is made of linear low-density polyethylene (LLDPE) and low-density polyethylene (LDPE), chosen for its low cost, chemical resistance, impact resistance, and insect resistance. The pouches are designed to be airtight, preserving food and slowing bacteria growth. This means that MREs can store food for extended periods and are far more efficient than landfills. However, the plastic packaging generates waste.
While some MRE packages are designed to be used multiple times, and some are biodegradable, the majority are single-use. As a result, MRE packaging waste is either left behind in the environment or recycled or incinerated at a cost of several million dollars per year.
The good news is that advancements in distributed recycling technologies now allow for on-demand reconstitution of MRE pouch waste into useful appliances via material extrusion additive manufacturing. Recycling of MRE pouch materials through a combined compounding, filament extrusion, and fused filament fabrication (FFF) additive manufacturing protocol has been demonstrated, with the mechanical properties of the additively manufactured structures found to be comparable to the native pouch materials.

MREs are used by the military
Meals, Ready-to-Eat (MREs) are self-contained, individual field ration packs used by military personnel. They were first introduced for use in the US military in 1981 and have since been a staple of military rations. MREs are packaged in plastic, specifically in flexible cans made of thick aluminium foil and plastic layers. Each year, military forces consume upwards of 144 million MREs in the field, resulting in the generation of thousands of tons of residual polymeric packaging waste.
MREs are designed to be disposable and provide a logistical necessity for the military. They can be distributed to large numbers of people quickly and have a sturdy shelf life. Military MREs are mass-produced and sent out by the thousand, with strict packaging requirements. The packaging must be able to withstand parachute drops from 380 metres (1,250 ft) and non-parachute drops of 30 metres (98 ft). It must also maintain a minimum shelf life of three and a half years at 27 °C (81 °F) and nine months at 38 °C (100 °F).
MREs are intended to be eaten for a maximum of 21 days and have an average shelf life of three years. They are heated using a flameless heating element/flameless ration heater, which allows soldiers to have a hot meal in under 10 minutes, regardless of their access to a stove or electricity. Each MRE provides about 1,200 kilocalories (5,000 kJ).
The procurement and sale of MREs by military personnel for personal profit are illegal under the Uniform Code of Military Justice Article 108. However, MREs have made their way into the civilian market through various manufacturers and distributors. Civilians use MREs for emergency preparation, remote occupations, and outdoor activities such as hiking and camping.

MREs are popular with campers
Meals Ready to Eat (MREs) are a popular choice for campers and backpackers. They are a quick, convenient, and nutritious option for campers, offering a range of benefits that make them ideal for outdoor adventures.
MREs are designed to be consumed either hot or cold, making them versatile for various camping scenarios. They usually come with self-heating packets, although some require water to be added. This can be a more sustainable option than building a fire or carrying a stove, especially when clean water is accessible. MREs are also known for their long shelf lives, typically lasting around five years when stored at room temperature. This makes them reliable for camping trips, ensuring that campers always have access to edible meals.
Portion sizes of MREs are generous, ensuring that campers get their fill after a long day of activities. They often include a nutrition bar or cracker, peanut butter or cheese, cinnamon candies, and a coffee or cappuccino-style drink. Some brands, like MRE Star, offer vegetarian options and smaller portion sizes for those who prefer to supplement their MREs with fresh produce.
Another advantage of MREs is their ability to cater to a variety of dietary needs. For example, XMRE offers halal, kosher, and lite cases, as well as extended-shelf-life meals that can last up to 10 years. This extended shelf life is particularly appealing for campers who may be stocking up on supplies for extended periods in remote locations.
However, one of the main drawbacks of MREs is the waste generated from their packaging. MREs are typically packaged in plastic pouches, which contribute to the growing problem of plastic waste. While some MREs, like German MREs, are packaged in aluminium, most use plastic. This has prompted concerns about the environmental impact of MREs, especially when used extensively during camping trips.
Despite this drawback, MREs remain a popular choice for campers due to their convenience, nutritional value, and versatility. Campers must carefully consider the benefits and drawbacks of MREs and make informed decisions to balance their needs with environmental sustainability.

MREs are made of plastic and aluminium
Meals, Ready-to-Eat (MREs) are packaged in flexible cans made of thick aluminium foil and plastic layers. The plastic used in MRE packaging is typically low-density polyethylene (LDPE), chosen for its low cost, chemical resistance, impact resistance, and insect resistance. LDPE is one of the most widely recycled plastics, but it is important to note that not all types of LDPE are recyclable. The aluminium foil used in MRE packaging is also widely recycled.
The MRE package, also known as a tri-laminate retort pouch, serves as a critical tool for extended military missions. Each year, military forces consume upwards of 144 million MREs, generating thousands of tons of residual polymeric packaging waste. This waste is either left in the environment, recycled, or incinerated at a significant cost.
The use of plastic packaging in MREs has raised environmental concerns among consumers. While some countries have made progress in reducing plastic waste, recycling rates vary worldwide, and plastic production continues to increase. The long shelf life and non-porous nature of plastic make it useful for long-term food storage, but the plastic in MREs contributes to the growing issue of plastic pollution.
To address these concerns, some consumers seek alternatives to reduce plastic waste. For example, German MREs are known for their minimal use of plastic, with packaging primarily made of aluminium. Others opt for reusable containers and flatware to minimise their plastic waste.
While complete recycling of all plastics may not be feasible, conscious efforts to reduce, reuse, and recycle can collectively contribute to more sustainable waste management. Advancements in distributed recycling technologies have enabled the recycling of MRE pouch materials into useful appliances through material extrusion additive manufacturing. These recycling processes have been found to have minimal effects on the mechanical and barrier properties of the resulting structures.
