=== Coconuts ===
Coconut shells and husks, which were discarded by coconut vendors, previously blocked the rivers of Las Piñas and Zapote. Currently, coco coir nets are being utilized for lining the riverbanks.

This efficient natural alternative for flood prevention is 80% more cost-effective than traditional riprap techniques such as cement and stone and is also effective for stopping soil erosion.

Like a beehive comb, the net is woven to create openings for plant growth within the cells, allowing their long roots to help secure the soil. The coco coir net is more resistant to sun and water damage compared to plastic nets, making it more durable. Additionally, it is eco-friendly because the material breaks down gradually into tiny pieces that enrich the soil.

Additional applications for coir fiber involve utilizing it as a potting material for horticulture purposes, in hydroponic systems, and for managing erosion.

The different ways in which it is used have led to a higher need for the coconet, providing a means of income for several Las Piñas locals who turn coconut husks into nets through weaving.

The Las Piñas city officials have given out twining and weaving tools and offered electrical assistance to its residents who have turned coconet weaving into their personal family venture.<ref>{{Cite web |title=Coconut Livelihood |url=https://laspinascity.gov.ph/lifestyle/22/coconut-livelihood |access-date=|website=The Official Website of the City of Las Piñas}}</ref>

=== Salt-making industry ===
{{main|Salt industry in Las Piñas}}

During the 18th century, the fishing village of Las Piñas adopted salt-making techniques with the use of solar dry beds. Over the years, numerous hectares encircling the ancient town were transformed into salt beds named "irasan".

Afterwards, clay tiles or gibak were transported from as distant as Vigan to cover the salt beds. This kept the salt from touching the ground, resulting in the salt turning as white as snow and making Las Piñas known as a hub for salt production.

At the time of harvesting, Las Piñas was adorned with small white crystal pyramids. The salt was sorted and categorized into tertia, segunda, and primera grades.

Tertia salt was the darkest in color and had the highest amount of impurities. Dry ice was combined with this salt to keep ice cream fresh.

Segunda salt was utilized for the purpose of preserving fresh fish. Navotas and Malabon were the primary purchasers of segunda salt among the wholesale seafood trading communities.

However, Las Piñas was renowned for its high-quality salt, also known as primera, rumored to be as white as snow. The initial batch of salt was delivered to every public market in Manila and utilized to enhance the taste of gourmet meals.

The bay area's restoration and the resulting Coastal Road construction caused interference with salt production. The dredging and construction activities hindered fishermen from venturing out to the ocean. Most of the salt being produced started entering the cheaper segunda and tertia categories. Salt that was brought in from countries such as China and India was available for purchase at reduced costs. The salt production industry in Las Piñas has come to an end and is now just a reminiscence of the past.

In 2005, an Irasan Center was constructed where visitors could view a salt bed demonstration in commemoration of Las Piñas’ once much celebrated industry.<ref>{{Cite web |title=Salt-making industry |url=https://laspinascity.gov.ph/lifestyle/24/salt-making-industry |access-date= |website=The Official Website of the City of Las Piñas}}</ref>
