MANASQUAN, NJ - March 31st, 2026 - Liam Murphy, a junior at Manasquan High School, is gaining significant attention for his innovative research into sustainable beach erosion control. Murphy's project, focusing on the viability of biodegradable sand fencing crafted from coconut coir fibers, recently earned him accolades at the regional science fair and a coveted spot in the state-level competition. His work is sparking conversation among coastal communities and environmental scientists alike, offering a promising alternative to the ubiquitous - and problematic - plastic sand fencing currently used to protect vulnerable shorelines.

Beach erosion is a critical issue facing coastal regions globally. Rising sea levels, intensified storm surges due to climate change, and increasing human activity all contribute to the gradual loss of valuable beachfront property and vital coastal ecosystems. Traditional methods of combating erosion, such as building sea walls and implementing beach nourishment projects (adding sand to eroded areas), are often costly, environmentally disruptive, and offer only temporary solutions. Sand fencing, designed to trap windblown sand and encourage dune stabilization, has become a common mitigation strategy, but the vast majority of this fencing is made of plastic.

This plastic, while initially effective, presents a significant environmental problem. Broken pieces inevitably wash ashore, contributing to plastic pollution that harms marine life, litters beaches, and degrades the aesthetic value of coastal environments. Microplastics, resulting from the breakdown of larger plastic debris, are particularly concerning, as they enter the food chain and pose potential health risks. Murphy recognized this issue and sought a more ecologically responsible approach.

"I've always been interested in the environment and spending time at the beach," Murphy explained in an interview. "I noticed how much plastic fencing washes up after every storm, even seemingly small pieces. It bothered me that something designed to protect the environment was actually contributing to pollution. I started thinking about natural materials that could serve the same purpose, but decompose safely."

Murphy's research centered around coconut coir, a fibrous material extracted from the husk of coconuts. This byproduct of the coconut industry is already widely used in gardening and erosion control applications, such as coir mats and logs. Murphy hypothesized that woven coconut fibers could provide a robust and biodegradable alternative to plastic sand fencing. He meticulously designed and constructed sections of coconut fiber fencing, comparable in size and structure to standard plastic fencing.

His experiment involved a comparative analysis of the two materials. Murphy tested their structural integrity under simulated wind and wave conditions, measured their ability to trap sand, and monitored their rate of decomposition. The results were encouraging. The coconut fiber fencing demonstrated comparable stability and sand retention capabilities to the plastic fencing. More importantly, it began to break down naturally within a controlled timeframe, leaving behind only organic material that enriched the dune ecosystem rather than persistent plastic waste.

"The initial data is really promising," states Dr. Eleanor Vance, a coastal geologist at Rutgers University who served as a consultant on Murphy's project. "Liam's approach addresses a critical gap in sustainable coastal management. While plastic fencing is cheap and readily available, the long-term environmental costs are substantial. Coconut coir offers a viable, biodegradable solution that could significantly reduce plastic pollution on our beaches."

The implications of Murphy's research extend beyond Manasquan. Coastal communities across the country, and globally, are increasingly seeking sustainable solutions to address the challenges of beach erosion. The adoption of biodegradable sand fencing could represent a significant step towards more responsible and environmentally friendly beach management practices. Murphy is currently exploring scaling up his project, investigating the potential for local production of coconut coir fencing, and collaborating with environmental organizations to pilot its implementation on larger-scale projects. His initiative proves that innovative solutions to complex environmental problems can originate from anywhere - even a high school science fair project.
