Introduction

Pollution prevention (P2) has become a vital focus in industries historically associated with environmental concerns, notably dry cleaning and hydraulic fracturing. Both sectors face scrutiny due to their potential environmental impacts, primarily from the use of hazardous chemicals and water contamination risks. Exploring sustainable and cost-effective alternatives, such as liquid carbon dioxide (CO₂), is crucial for advancing environmentally responsible practices. This paper reviews key scholarly articles addressing pollution issues and solutions in these industries, emphasizing the viability of liquid CO₂ as an eco-friendly substitute.

Dry Cleaning Industry: Process, Issues, and Alternatives

The article by Sinshelmer et al. (2007) discusses professional wet cleaning as a pollution prevention strategy in place of traditional dry cleaning with perchloroethylene (PCE). Typically, dry cleaning uses PCE due to its effectiveness in removing stains, but it is a chlorinated solvent linked with environmental and health problems, including air and water pollution and carcinogenic risks. The process involves cleaning garments with PCE in specialized machines, which often result in solvent emissions and waste disposal issues. PCE's toxicity and volatility pose significant environmental hazards, prompting the search for safer options.

The authors analyze alternative cleaning methods, focusing on wet cleaning techniques that utilize water and biodegradable detergents. These methods reduce chemical emissions and water pollution. The study shows that professional wet cleaning is not only effective but also environmentally safer and economically feasible, highlighting its potential as a pollution prevention measure. Transitioning from PCE to wet cleaning requires industry adaptation, but it aligns with increasing regulatory pressures and consumer demand for greener practices.

Environmental and Pollution Prevention Issues in Hydraulic Fracturing

The articles by Heywood (2012) and Chen et al. (2014) examine hydraulic fracturing, a technique to extract natural gas and oil from deep underground formations. While economically beneficial, hydraulic fracturing raises significant environmental concerns, including groundwater contamination, excessive water use, and air pollution. The chemicals used in fracturing fluids, often proprietary and undisclosed, pose risks of contaminating water supplies, while the fracturing process itself can cause seismic activity and gas leaks.

Both articles discuss pollution prevention strategies, emphasizing the importance of innovative solutions. Heywood (2012) advocates for safer fracturing practices, including better chemical management and monitoring. Chen et al. (2014) introduce the concept of using liquid CO₂ as an alternative fracking fluid. Liquid CO₂ is non-toxic, non-flammable, and environmentally benign, with the potential to reduce the chemical footprint and water usage in fracturing operations. The adoption of liquid CO₂ could mitigate many environmental risks if industrially scaled and economically justified.

Application of Liquid CO₂ in Industry: Insights from Taylor et al. (2010)

Taylor et al. (2010) explore the use of liquid CO₂ as a pollution prevention technology, highlighting its application in both dry cleaning and hydraulic fracturing industries. In dry cleaning, liquid CO₂ serves as a solvent that effectively cleans garments without the toxic emissions associated with PCE. It operates at high pressure and low temperature, capturing dirt and grease while remaining environmentally friendly. The process reduces volatile organic compound (VOC) emissions and energy consumption.

Similarly, in hydraulic fracturing, liquid CO₂ can replace water-based chemicals, creating a less contaminating and more sustainable process. Its properties enable it to fracture rock formations efficiently, dissipate quickly after use, and minimize water usage. Taylor et al. demonstrate that integrating liquid CO₂ into these industries aligns with pollution prevention goals, offering effective cleaning and extraction solutions while reducing environmental impacts and health risks. The technology shows promise as a cost-effective, scalable alternative that supports industry sustainability.

Summary and Critical Evaluation

Overall, pollution prevention in dry cleaning and hydraulic fracturing has evolved with technological innovations like liquid CO₂, which offer promising environmental benefits compared to traditional methods. Liquid CO₂ is inherently non-toxic, recyclable, and reduces harmful emissions, positioning it as an ideal substitute for hazardous chemicals like PCE and water-based chemicals in fracturing. While initial costs for implementing CO₂-based systems may be higher, long-term savings in emissions reduction, regulatory compliance, and public perception favor its adoption. The current evidence suggests that liquid CO₂ can be a reasonable, cost-effective, and environmentally friendly alternative if industry barriers and infrastructure needs are addressed.

However, broader application depends on technological advancements, economic incentives, and regulatory support. Further research into optimizing CO₂-based cleaning and fracturing techniques is necessary to improve efficiency and reduce costs. Although challenges remain, the shift toward liquid CO₂ demonstrates industry’s movement toward more sustainable practices, reducing ecological footprints and promoting public health. It’s vital that ongoing innovation continues to refine these methods, making them accessible and practical for widespread adoption.

Conclusion

Pollution prevention in both dry cleaning and hydraulic fracturing industries holds the key to sustainable development. The shift from toxic chemicals like PCE to cleaner alternatives such as liquid CO₂ presents considerable environmental and health benefits, demonstrating technological feasibility and economic potential. Supporting policies, industry adoption, and continued research are essential in realizing the full benefits of liquid CO₂ technology, ultimately fostering safer, greener industrial processes that protect our environment for future generations.
