MANILA, Philippines -- Scientists of the Department of Science and Technology (DOST) are exploring another use for paper mulberry, the invasive plant species locally known as “lapnis,”

Last year, the FPRDI completed its study seeking to assess the coppicing of lapnis. This is the practice of cutting trees or plants to further stimulate their growth.Eventually five different kinds of handmade papers were developed from that research and were evaluated by a conservator.

Paper mulberry shrubs are seen at a roadside on the way to Mt. Makiling in Los Baños, Laguna province.Top importerAustria said developing paper from lapnis may reduce the country’s dependence on importing these kinds of materials.Based on World Bank data in 2019, the Philippines was 27th out of 146 top importers of handmade paper and paperboard products at 386 tons, worth $509,000.

This is the practice of cutting trees or plants to further stimulate their growth. Eventually five different kinds of handmade papers were developed from that research and were evaluated by a conservator. This is the reason why Councilor Alvin Dizon is urging Mayor Michael Rama to reconsider his plan to establish a WTE and a city owned and operated power plant. Paper mulberry shrubs are seen at a roadside on the way to Mt. Makiling in Los Baños, Laguna province. “As to the first proposal of the mayor, I strongly argue that the adoption of WTE technology is not a solution to address the city’s power generation and waste management system. Top importer Austria said developing paper from lapnis may reduce the country’s dependence on importing these kinds of materials. The local government said 100 seedlings were distributed in Simona Subdivision, Brgy.

Based on World Bank data in 2019, the Philippines was 27th out of 146 top importers of handmade paper and paperboard products at 386 tons, worth $509,000. Dizon spoke to air his opinion on the mayor’s plan to establish a WTE facility and power plant here as part of his post-Odette recovery plan. These products were shipped from the United States, China, Australia, Turkey, Japan and Thailand. Austria said there would be further studies at the FPRDI to improve the lapnis paper’s color, fiber formation and distribution, and clarity—its being free from specks, dirt and other foreign particles. During his speech, Dizon said, studies that were made earlier show that WTE’s are detrimental to the environment. The Institute also offers training on lapnis handmade paper production. Inquiries may be emailed to its Training and Manpower Delivery Services Section via [email protected] ADVERTISEMENT Lapnis, which is native to East Asian countries such as China, Japan and Korea, can be classified as a large shrub or a small tree, growing from 10 to 20 meters, with a soft and brittle wood. Dizon is asking Rama to find other solutions to the city’s power and garbage woes that are sustainable and environment-friendly like the full implementation of a “Zero Waste” program by recycling, composting and reuse. Rebecca Ynares, Rizal Vice Gov.

Its timber has little or no commercial value other than for papermaking. Its parts are known for having medicinal benefits. On Rama’s plan to put up a power plant here, Dizon said, having a coal-fired power plant is dangerous for the city. The leaves are used as a laxative, the bark, to treat dysentery and hemorrhage, and the fruits made into a tonic. The sap is applied to eczema, bee stings and bites from snakes and dogs. That resolution was passed by the 13th Sangguniang Panlungsod and had been replicated by other local governments. Alien plant Lapnis was introduced to the country in 1935 as part of a reforestation program to augment the bast fiber-producing tree crops at the Makiling Forestry School campus in Laguna province. According to the Rizal Public Information Office (PIO), the local government has chosen bamboo trees because their stability can strengthen the lands near the rivers to prevent landslides and flooding.

Over the years, however, lapnis had come to be known as a “pest”—thriving uncontrollably, especially in the Mt. “A coal power plant which burns dirty and deadly coal to generate electricity has no place in a climate vulnerable city like Cebu. Makiling Forest Reservation, where it badly affected the growth of other flora. The Department of Environment and Natural Resources listed lapnis among the invasive alien plants “as it invades young secondary forests and retards the natural ecological succession in forest gaps. Dizon said that while it is important for the city to be disaster-resilient, this should not be done at the expense of the environment.”But in 2017, the DOST’s Philippine Council for Agriculture, Aquatic and Natural Resources Research and Development funded a study on lapnis to find ways to control its spread. Based on its trials, the FPRDI was able to produce charcoal, briquettes, handmade paper and light-load bearing furniture that passed quality standards from lapnis wood. The last thing that Cebu City should do is to aid global warming and be a contributor to future major disasters, he added. Around 2,000 bamboo seedlings were planted in Hinulugang Taktak in Antipolo City on Dec.

“We want to help control the continued spread of paper mulberry in the country, not by killing off the shrubs but by finding possible uses for their wood,” said FPRDI scientist Pablito Alcachupas, the project leader of an earlier study by the Institute. He added: “The long-term goal is to be able to establish well-managed paper mulberry plantations in the future. I agree to the.” .
