Understanding the Performance of Domestic Biodigesters in Bangladesh: A Study from Household Level Survey

Biogas can be an important alternative energy source for the sustainable development of the energy sector. To understand the performance of the family-size biodigester in Bangladesh, a household level survey on randomly selected 360 biodigester adopters was conducted. It is evident from the study that adoption of biodigester at the household level is economically and environmentally viable. Most of the biodigesters were constructed for single household and production of biogas was sufficient for cooking for single household. About 35% of biodigesters generated surplus gas from which they earned money by selling the surplus gas. About 91% of the biodigesters were feed with cow dung, one of the optimal biogases producing substrates, which has easy access in their own households. The factor analysis suggests that the most important factors to make biodigester economically viable are: capacity of biodigester, availability of substrates, amount of investment for biodigester, and economic benefits derived from biodigester.

Alternative Energy Source

Biomass briquettes have been made as an alternative energy source from cow dung waste. Molasses and starch were used as binder material with a carbonization temperature of 400 °C for 2 hours. The work aims to produce biomass briquettes with the best heating value based on analysis of composition effect and type of binder on the briquette with calorific value. The heat test results showed that briquettes with 10% sugar cane binding content produced the highest calorific value of 3907.5 calories/gram. Sugar cane drops become the better binder than starch in biomass briquettes production.

Wide Range

This article covered a wide range of questions on the topic of production and use of biogas as alternative energy source. Biogas is produced by anaerobic digestion of biomass due to the breakdown of fats, proteins and carbohydrates, which constitute the bulk of organic matter. The article describes the most common methods of biogas production, their stages and characteristics. In addition, the article describes some of the possible areas of application of biogas on example of different countries. The article also provides information about key environmental and economic benefits in the case of use of biogas: prevention of methane emissions and lower emissions of carbon monoxide and nitrogen oxides into the atmosphere; the possibility of using secondary raw materials to generate electricity.

The Ideal

Renewable energy represents a major interest field in the sustainable development of the energies reserve. Agri-pellets are an efficient version of the average pellet, both in reducing greenhouse gas emissions and in reducing energy costs. Agri-pellets are obtained through mixtures of vegetal and forestry waste, being an alternative to the usual pellets because the material that is used in the process can be easily found, especially in the case of farms. Agricultural and forestry biomass represent the raw material for pellets and agri-pellets processing, a product that is used as an alternative energy source to classic versions (wood). The mixtures humidity is very important because it has a major impact on product quality. Determining the ideal humidity for each type of pellets/agri-pellets is important in order to establish optimal mixtures, this paper presenting research results on determining the humidity influence on pellet and agri-pellet recipes.
