Gel blasters are toy devices that launch small, water-absorbent pellets. They use a spring-loaded mechanism or an electric motor to propel gel balls. Their design often mimics real firearms, yet they are considered safer due to their projectiles. As these blasters gain popularity, questions about their environmental impact arise. This article examines the ecological footprint of both the gel balls and the blaster devices.
The Environmental Footprint of Gel Balls
Gel balls, also known as water beads or gellets, are gel blaster ammunition made primarily of superabsorbent polymers (SAPs). Sodium polyacrylate, the most common material, absorbs hundreds of times its mass in water, expanding from tiny pellets to soft, 7-8mm balls. While some manufacturers market them as “all-natural” or “starch-based,” their chemical composition often remains a synthetic polymer.
Claims of biodegradability for gel balls are common. However, sodium polyacrylate, the main component, is not inherently biodegradable in a short timeframe, taking 20-30 years to fully degrade in natural soil. Degradation occurs over time through exposure to sunlight and microbial activity, causing the balls to dehydrate and disintegrate into smaller fragments. These fragments are mostly water and burst upon impact, reducing visible residue.
Despite their non-toxic nature, the long degradation period of sodium polyacrylate raises concerns about environmental accumulation. As gel balls break down, they can form microplastic particles that might persist in soil and water. While generally considered safe, large quantities could potentially disrupt ecosystems. There is also a risk of ingestion by wildlife, though their non-toxic composition means direct harm is unlikely.
The Environmental Footprint of the Blaster Device
Gel blaster devices contribute to an environmental footprint. These blasters are typically constructed from various plastics, such as ABS plastic or nylon, though some models may incorporate metal components. The production of plastic toys, including gel blasters, is an energy-intensive process that consumes resources and releases greenhouse gases. This manufacturing process can also involve harmful chemicals, contributing to air and water pollution.
The non-biodegradable nature of plastics means discarded blasters can persist in landfills for hundreds of years. As plastics break down, they contribute to microplastic pollution, which can contaminate ecosystems and potentially enter the food chain. Many gel blasters are battery-powered, frequently utilizing lithium-ion batteries.
The life cycle of lithium-ion batteries carries environmental consequences. Extracting raw materials like lithium and cobalt involves mining practices that can lead to water depletion, chemical leakage, habitat destruction, and soil erosion. Manufacturing these batteries is energy-intensive, adding to their carbon footprint. Improper disposal poses risks such as toxic metals leaching into soil and water sources, and fire hazards in landfills due to their unstable components.
Minimizing Environmental Impact
Users can take steps to reduce the environmental impact of gel blasters. Collecting spent gel balls after play is beneficial, especially in contained areas. While many are marketed as biodegradable, sodium polyacrylate degrades slowly. If local regulations permit and the balls are truly biodegradable, disposing of them in a compost bin or organic waste system is preferable. Otherwise, general waste disposal is the appropriate method.
Reusing hydrated gel balls is generally not recommended for optimal performance, as their integrity can be compromised. However, dry, unhydrated gel balls can be stored indefinitely. Hydrated ones can last for weeks or months if properly submerged in water and kept in an airtight container away from direct sunlight. Avoiding over-soaking also helps maintain their quality and reduces waste.
Proper disposal of the blaster device is important due to its plastic and electronic components. Gel blasters and their batteries should not be discarded in household trash. Instead, take them to electronic waste (e-waste) recycling facilities. Lithium-ion batteries, in particular, require specialized recycling to prevent the release of hazardous materials and recover valuable components. When purchasing new blasters, considering products made from more durable materials or those with clear environmental claims can contribute to a reduced impact.
