How to convert Waste to Briquettes (2023 edition)?
Don’t squander, don’t crave. What we often perceive as trash could actually be a treasure. In the past, we’ve seen our everyday garbage as something without value. But if we shift our perspective towards resource optimization, we can see that these everyday discards can be reclaimed, recycled, and repurposed at every stage of our production and consumption processes.
Waste to Briquettes
Trash can be sorted into various types depending on where it comes from. Typically, we can categorize it into municipal, residential, commercial, industrial, construction and demolition, hazardous, and other types of waste. Residential waste, which we encounter daily, includes everything from organic kitchen and garden waste to recyclable materials like paper, textiles, and plastics, as well as non-recyclable and hazardous waste like batteries.

Residential waste, which we encounter daily, includes everything from organic kitchen and garden waste to recyclable materials like paper, textiles, and plastics, as well as non-recyclable and hazardous waste like batteries.
It’s worth noting that a staggering 80-90% of all waste ends up in landfills without being efficiently separated or recycled. This raises a crucial question: How can we identify the valuable elements in our daily waste and turn this ‘trash’ into treasure?
Â
The first step is to understand the composition of the waste. This involves determining the moisture content, calorific value, and chemical composition.
Moisture Content
The moisture content of waste directly affects how it’s disposed of. Depending on the moisture content, waste can be turned into compost or biogas, used as solid fuel, or simply dumped in a landfill. There are various tools available to measure the moisture content of waste.
Calorific Value
The calorific value of waste indicates its energy value, which is influenced by its moisture and hydrogen content. To determine the calorific value, waste should be sorted into sample fractions and analyzed.Â
The calorific value of dried materials and the hydrogen percentage are used from known data. The moisture content of the fractions is then determined, and the calorific value of the fraction is calculated using a specific formula. (Calculate for fraction calorific value( shortened as CV raw) according to the formula below:)
CVraw=??1-MC?*( CVupper-(2241* 9)*H)?-2441*MC.)
Chemical Composition
The chemical composition of waste refers to elements like carbon, oxygen, hydrogen, sulfur, nitrogen, and others. This composition affects how waste is disposed of.
Everyday solid waste is usually a mix of different components. Some of these can be turned into fuel, while others cannot. The following table (not included here) can be used as a reference, but it may need to be adjusted based on local regulations or laws in each country.
Wastes for Briquettes Production
For high-energy solid waste, one method of transforming this ‘trash’ into treasure is through briquetting. This technique involves compacting loose, combustible materials into solid shapes of various sizes, using pressure and binding agents.
A variety of materials can be used to create briquettes, including waste paper, cardboard, water hyacinth, agricultural byproducts, charcoal dust, and wood waste such as sawdust.
Advantages of Turning Waste Into Fuel Briquettes
Using fuel briquettes reduces the need for firewood and charcoal, saving both time and money while also easing environmental strain.
If you make your own briquettes, you’ll have a free source of fuel for cooking!
You can earn extra income by selling your homemade briquettes.
Creating briquettes from everyday waste reduces the amount of garbage on the streets and in landfills.
Briquettes are durable, burn efficiently, and are easy to store and transport.
However, Briquetting Does Have Some Downsides
Large-scale briquetting equipment requires a significant investment, and small-scale briquette production equipment isn’t widely used.
Wet weather can decrease the density of briquettes, negatively affecting their quality.
Briquetting Making Process
Typically, the process of making briquettes involves the following steps:
Preparing raw materials: This involves mechanically breaking down raw materials using a crushing machine. The quality and size of the materials, as well as the technology used, can influence this process, which can be done in stages.
Â
Drying the crushed materials if their moisture content is too high for briquette production.
Â
Forming briquettes from the processed materials using various types of briquetting machines, such as screw pressing machines, stamping pressing machines, and hydraulic briquetting machines. The briquettes are formed through a process of pressure agglomeration, where loose materials are molded into a permanent shape with defined dimensions through compaction pressure and intermolecular forces and bonds when necessary.
Briquetting Densification Technology
Briquetting is a densification technology that turns biomass waste into a solid and convenient fuel. There are several types of briquetting technologies based on the mechanical features and equipment used: piston press densification, screw press densification, roll press densification, and manual presses.
Piston Press Densification Technology
Piston Press densification technology is typically used for large-scale production, ranging from 200 to 2,500 kg/h. This technology uses a mechanical piston press, which is an eccentric press by design.Â
The mechanical piston press is driven by an electric motor, which minimizes energy loss and optimizes output relative to power consumption. Compared to the hydraulic press, the mechanical piston press has a longer working life and provides a better return on investment.
Screw Press Densification Technology
Screw Press densification technology can compact materials at ratios ranging from 2.5:1 to 6:1 or even more. During briquetting, the feedstock is extruded through a taper die under high pressures and temperatures, which meld the lignin present to function as a binder. The high temperature carbonizes the outer layer of the briquette, and the center hole of the briquette promotes combustion efficiency.
Roller Press Densification Technology
Roller Press densification technology densifies biomass material based on the principle of pressure and agglomeration. The quality of the densified fuel is closely related to the parameters of the roller presses, such as the diameter of the rollers, the shape of the die, the gap width, and the force of the rollers.
Manual Presses
Manual presses are often used in developing countries. They have the advantage of low investment and operation costs and require low skill levels. However, manual briquettes presses mold the feedstock with lower pressure and high moisture content, which needs to be dried after shaping into briquettes. The dried briquettes have low strength and can crumble easily.
Briquette fuel is commonly used in boiler plants, heating plants, power stations, and thermal power stations, as well as by individual customers for household use. It can also be used in fireplaces and conventional boilers that once used coal or wood, with or without minor modifications.
 The rising cost of conventional fuels increases the demand for briquette fuel, affecting its price and the price of briquette machines, as public awareness of environmental protection grows.
