Agro Waste Briquette

Agro Waste Briquette

Agro waste briquettes are made from various agricultural residues such as mustard waste, rice husk, arhar stalks, ground nut shells, leaves , coffee husk etc. These can serve as an ideal alternative to traditional fuel sources such as coal and charcoal owing to the briquettes being comparatively less polluting to the environment and also having a much higher calorific value. Furthermore, as compared to coal and charcoal, agro waste briquettes burn for a much longer time and also generate lesser amount of ash.

Billions of tons of agricultural waste is produced every year. The handling and disposal of the wastes is a common problem, with many man hours spent in their disposal. A majority of farmers today burn the agro residues openly, yet these do not burn completely, resulting in high environment pollution along with a lot of leftover residues.

This is the reason why the use of agro waste briquettes is increasingly finding favor amongst people, along with solving the disposal problem of agro residues, these also provide more efficient burning.

Major Processes Associated With Agro Waste Briquette Making

Collecting agricultural waste and their preparation

Preparation of binder

Preparation of briquettes

Drying of the prepared briquettes

Firing of the briquettes

Cooling process

Agro Waste Briquettes are an Ideal Energy Source Because:

Many people in developing or underdeveloped countries still do not have access to electricity and cooking gases. Agro waste briquettes, being cheaper and readily available compared to other fuel sources can be used by people who are below the poverty line.

Since, the briquettes are a renewable energy source, these do not have uncertainties associated with their continuous supply.

Developed countries are the biggest contributors of greenhouse gases to the atmosphere. The united nations has established a voluntary carbon credits scheme aimed at reducing overall pollution. As a result, due to their minimal polluting nature, these briquettes are increasingly finding favor in varied countries across the globe.

These can be made from low grade as well as high grade agro residues, giving the same heat output. Thus the problem of incomplete or spontaneous combustion so prevalent in coal, firewood or charcoal is eliminated.
