- 16. Quantitative research design employing comparative-developmental was used in this study. Comparative design was used to compare the level of efficiency of the food waste and cow dung biogas and the commercial LPG. Developmental was used to produce biogas using food waste. In addition, the locale of the study was done in Zone 5, Matucay, Allacapan, Cagayan, and its efficiency was in the same locale.

Editor's Notes
- Create a biogas digester. Collect the stored organic waste. (Chop the food waste into small pieces.) 3. Load and mix waste in the digester (Then mixed it well with the cow dung and add some water. This fasten the decomposition of the food waste) 4. Establish optimal operating conditions (The researchers set the digester in direct sunlight. The sunlight needs to provide the energy plants need to convert carbon dioxide and water into carbohydrates and oxygen. It helps to decompose the food waste and cow dung and turn it into biogas) 5. Capture and store the biogas. (The researchers sought assistance from expert in Centro East, Allacapan, Cagayan to transfer the biogas to a cylinder gas. Consulting with experts in biogas production and handling, as well as adhering to safety guidelines, is crucial throughout the entire process) 6. Use your biogas.(The researchers boil 200 ml water to determine the time consumption, cooking time and heat quality. Ten replications were done to ensure reliability of data. )
- Anaerobic digestion is a biological process that breaks down organic matter, such as fruit/vegetable peelings, left over rice, rice water and so much more in the absence of oxygen.
- Table 1 shows the amount of food waste and cow dung needed to generate biogas in eight weeks. Evident in the table that pure 20 kg of food waste and pure 20 kg of cow dung cannot produce biogas. On the other hand, Table 1 reveals that 15 kg of food waste mixed with 5 kg of cow dung produced biogas. This result suggests that the production of biogas is more feasible when food wastes and cow dung are mixed together.
- Table 2 demonstrates the production time of biogas from food waste and cow dung. The table shows that 20 kg pure food waste and 20 kg of pure cow dung did not produce biogas in 4 weeks, while the 15 kg of food waste combined with 5 kg cow dung were successfully converted within 7 days. This result is faster than the approximate time conversion of food waste and cow dung to biogas stated in the study of Shaibur, et.al. (2021) that most of the organic matter is broken down into biogas in approximately three weeks.
- Table 3 presents the level of efficiency of food waste and cow dung biogas and Liquefied Petroleum Gas (LPG) in terms of heat/flame quality, consumption time, and cooking time. Evident in the table that LPG has slightly higher heat/flame quality over the three-minute time interval. In 1 minute it reached 121.49°C, in 2 minutes it reached 170.62°C, and 224°C in 3 minutes. On the other hand, the heat/flame quality of biogas is lower at certain points. At 1 minute, its heat quality is 110.34°C, 157.51°C in 2 minutes, and 220.3°C 3 minutes. This finding means that compared to biogas, LPG has slightly higher heat quality. In terms of consumption time, it can be seen in the Table 3 that the average consumption time of biogas is 2.65 hours, while LPG is 3.62 hours which means that LPG can be consumed longer than the biogas at certain hours. With regards to cooking time using biogas and LPG, it can be gleaned from the table that it takes an average of 6.723 minutes for the biogas to boil water (100oC), while 6.559 minutes for the LPG. Thus, using biogas for cooking will slightly take longer time which is consistent with its heat quality.
- Table 4 indicates the comparison between the efficiency of the biogas from food waste and cow dung and the commercial LPG in terms of heat quality and cooking time. Apparent in the table that there is no significant difference between the heat quality of biogas and commercial LPG in 1 minute, 2 minutes, and 3 minutes with p-value of 0.338, 0.038, and 0.038, respectively. Similarly, it was found out that there is no significant difference between the cooking time of biogas and commercial LPG indicated in the p-value 0.934. These findings imply that biogas and commercial LPG have the same level of efficiency in terms of heat quality and cooking time. Hence, it can be inferred further that the biogas is as efficient as the commercial LPG. Thus, food waste and cow dung biogas can be an alternative to liquefied petroleum gas similar with that of a biogas produced by a digester developed by Department of Science and Technology (DOST) (Philippine Star, 2007).
- Biogas is a sustainable and renewable energy source that is cheaper and more efficient than traditional LPG. It is an environmentally-friendly solution that has numerous benefits for the community.
- The livestock industry has numerous and diverse impacts on the environment. Biogas digester projects primarily aims to reduce water pollution from the environment. Investing in Biogas projects aligns with environmental goals by reducing greenhouse gas emissions, mitigating climate change, and promoting sustainable waste management practices. Biogas is ideal for cooking and heating in households as it offers a reliable and efficient energy source without bringing much harmful smoke like LPG. Many small businesses such as restaurants and food vendors can benefit from using biogas which is cheaper and more sustainable than LPG. Biogas can be produced using cow dung, crop residues, and municipal solid waste, making it an ideal solution for farmers looking to generate their own energy and reduce waste. Biogas presents an eco-friendly and sustainable alternative to LPG, with positive impacts on the environment, community, and individuals. By harnessing the power of organic waste, we can pave the way for a cleaner, greener, and more self-sufficient future.
