Trash to cash: Gov’t helping Cagayan farmers use rice straw in mushroom production

The vast and fertile soils of the Cagayan Valley Region produce various agricultural products such as rice, corn, coconut, legumes, nuts, and many others. But with the abundance of harvests, there are always parts of the plants that, if not processed, will turn into waste. 

One of these is the rice straw, locally known as “dayami”. Farmers often burn these after harvest. But in Sitio Tayak, Siguiran, Abulug, and Cagayan, rice straw is used as a material for mushroom production by the Tayak Agri-Fisheries Producers Association. 

Sitio Tayak is home to hundreds of farm laborers. However, farming is a seasonal livelihood to them as they are only needed during land preparation, planting, and harvest season.

In 2019, the local government unit of Abulug and the Department of Labor and Employment organized them to create a livelihood for them to be busy during lean months. DOLE gave them P330,000 in seed capital for them to venture into mushroom production, which eventually became successful. 

The group is not only producing fresh cultured oyster mushrooms but they are also producing other by-products including mushroom bagoong, mushroom chips, mushroom pizza, dried mushrooms, mushroom pickles, and others.

"Through the seed fund and the training skills we provided them, the association has already developed into one of the major producers of mushroom-based products in the region," Labor Regional Director Elpidio Atal Jr. said. 

He also said using rice straw as a material in the production of mushrooms is also their contribution to the environment, aligned with the goal of the environment department to avoid the burning of agricultural wastes to protect the ozone layer. 

Meanwhile, there are also local entrepreneurs assisted by the Department of Trade and Industry (DTI) that manufacture products using agricultural wastes. The Karigo Corn Husk Fashion and Accessories Association makes bags and home décor from corn husk, the San Mariano Banana Growers and Producers Association designs and makes origami-inspired crafts and wallpapers using banana stalks, and the Silya Home Furnishings of Nueva Vizcaya specializes in manufacturing functional stools and sign boards out of scraps. 

In Sanchez Mira, Cagayan, the Cagayan State University collaborated with DTI for the conduct of the 'Intensive Product Development-Technology Course' which aims to teach coconut growers, students, and faculty members how to process wastes from coconut.  

The group produced coco fiber and coco peat out of coconut shells. The coco fiber is transformed into coco coir which can be transformed further into ropes, twines, brooms, brushes, doormats, rugs, and others. The coco peat, on the other hand, is widely used as a growing medium for sprouts and seeds. It is also considered a clean substrate in gardening, the leading solution to clean, environmentally friendly agriculture.

With the continued collaborative training given by CSU and DTI, the coconut growers have further developed new products out of coconut shells such as planters, carpets, rugs, peat blocks, mattresses, brushes, key chains, wall decors, indigenous plates, cups, and others.

In Nueva Vizcaya, the Department of Agriculture trained members of the Corn Growers Association and Sta. Lucia Corn Farmers Cluster on corn silage and animal feed production using corn stalks as raw materials. These products benefit large animal raisers in the region. 

These are only a few of the innovations shared by the government with the farmers and other organizations not only to help them develop their livelihood but also to contribute to environmental protection and proper solid waste management. (OTB/GVB/PIA Region 2)
