This invention set the foundation for disposable drinkware. Plastic cups gained popularity much later, in the 1970s, with the introduction of iconic products like Solo’s red plastic cup. These plastic cups quickly became a staple at social events and parties due to their durability and convenience, especially for cold drinks.
1.2 Raw Materials and Production
Paper cups are made from paperboard derived from renewable wood pulp, typically coated with polyethylene (PE) or bioplastics like PLA to make them waterproof. Their production demands significant natural resources, with estimates indicating about 6.5 million trees cut annually to produce roughly 16 billion paper coffee cups worldwide. Paper cup manufacturing is resource-intensive, requiring substantial water, energy, and chemicals. You can find more about various options available in our paper cup guide.
Plastic cups are primarily molded from petroleum-based plastics such as polyethylene terephthalate (PET, #1), polypropylene (PP, #5), and polystyrene (PS). Producing plastic cups uses approximately 17% less energy, 42% less water, and 22% less petroleum than paper cup production. However, plastic cups depend on fossil fuels, raising concerns about non-renewability.
1.3 Environmental Footprint of Manufacturing
Manufacturing one paper cup releases about 110 grams of CO2, contributing to a larger carbon footprint compared to plastic cups, which have a smaller carbon footprint but their reliance on fossil fuels offsets some benefits. From 1960 to 2007, paper cup production rose by 300%, while plastic cups surged by 7000%, reflecting society’s growing dependence on convenient disposable products.
1.4 Cost Analysis

2. Environmental Impacts: Biodegradability, Decomposition, and Waste Management
2.1 Biodegradability and Decomposition Timelines
Paper cups biodegrade faster than plastic cups because they are mainly made from renewable paperboard. However, their plastic linings—usually polyethylene (PE) or bioplastic polylactic acid (PLA)—slow their complete decomposition. In landfills, paper cups can take 20 to 30 years to break down fully. During this time, their plastic lining decomposes anaerobically, releasing methane, a potent greenhouse gas, and microplastics that harm the environment. On the other hand, plastic cups made from PET (polyethylene terephthalate), polypropylene (PP), or polystyrene (PS) can persist for centuries. These plastics fragment into tiny microplastics that contaminate soil and waterways, posing threats to marine life and terrestrial ecosystems. While paper cups have better biodegradability, their plastic coatings still cause long-term environmental issues.
2.2 Recycling Challenges
Recycling paper cups faces significant obstacles due to their plastic lining. These linings require specialized recycling facilities that separate the paper fiber from the plastic, but such facilities are limited. As a result, many paper cups are discarded as regular waste rather than recycled. Plastic cups made from PET (#1) have more established recycling streams and infrastructure, allowing better chances of being recycled. However, plastic cups made from PP (#5) are less commonly recycled. Despite about 80% of the U.S. population having access to recycling, actual recycling rates for both paper and plastic cups remain low because people often find recycling inconvenient or confusing and contamination is high. This leads to many cups ending up in landfills or as litter.
2.3 Landfill and Pollution Concerns
The vast majority of single-use paper and plastic cups end up in landfills, causing waste to accumulate over time. Plastic cups degrade extremely slowly, lasting hundreds of years and breaking down into microplastics that pollute oceans, rivers, and soil. This pollution threatens wildlife and ecosystems and is difficult to clean up. Paper cups, while faster to decompose, still contribute to landfill mass and release methane when decomposing without oxygen. The environmental impact of these discarded cups remains significant, with both types contributing to waste issues and pollution problems.
2.4 Comparative Life Cycle Assessments
Life cycle studies comparing paper cups versus plastic cups show that neither option is clearly superior in all environmental categories. Plastic cups perform better in energy efficiency, using about 17% less energy and 42% less water during production, and require 22% less petroleum input compared to paper cups. They also have a smaller carbon footprint. However, paper cups outperform plastic cups in toxicity and biodegradability. This means paper cups break down more naturally and create fewer harmful chemicals but require more resources like water and energy to produce. Overall, the environmental impacts balance out, and neither paper nor plastic cups fully solve the sustainability challenges posed by disposable cups. Alternatives and improved waste management are necessary to reduce their environmental footprint.
| Property | Paper Cups | Plastic Cups |
|---|---|---|
| Biodegradability | 20-30 years (due to lining) | Centuries (PET, PP, PS) |
