Comparison of Different Straw Disposal Solutions

Globally, billions of tons of agricultural straw waste are generated annually, with corn straw, rice straw, and sugarcane bagasse constituting the majority. In China alone, agricultural activities contribute to as much as 1 billion tons of crop straw every year. While various methods exist for handling waste straws, each method presents its challenges. Therefore, it may be necessary to explore more solutions to address the challenges of straw. Below is a comparison of several common methods for straw disposal.

Straw/Stubble Burning

Burning straw used to be a widely used method. However, many countries have now prohibited it, categorizing it as illegal. It releases harmful CO, CH4, carcinogenic polycyclic aromatic hydrocarbons, etc. The generated heat penetrates the soil, destroying soil nutrients.

Straw turnover

Straw turnover refers to shredding straws and returning them into farmland to enhance soil fertility. However, straw is both odorous and hard, and its natural decomposition takes a considerable amount of time. This method can badly impact the cultivation of the next crop.

Processed into feed

Processing crop straw into feed is an effective means of recycling. However, it can’t dispose of all straws because the demand for feed in the livestock industry is limited. Therefore, diverse solutions are needed to tackle this challenge.

Straw power generation

This approach represents a sustainable way. But there are currently technical challenges. The diversity and complexity of straw materials make biomass combustion boilers have problems such as low efficiency, alkali corrosion, sulfur emission, coking, and slagging.

Why Choose Straw to Charcoal Solution?

Straw disposal is a crucial aspect of modern agriculture, and the choice of method greatly impacts the environment. Opting for a straw to charcoal solution brings such benefits:

Reduction and Resource Utilization

The straw charcoal making machine can turn large amounts of straws into valuable biochar, achieving “Reduction and Resource Utilization of Waste”. This aligns with sustainability goals.

Economic Benefits

Straw charcoal production can be economically viable. Rice husk charcoal is widely used in industry, agriculture, and other fields, and it has no worries about sales.

Various Straw Raw Materials

The straw charcoal machine accommodates various straw types, including:

  • Wheat straw
  • Barley straw
  • Oat straw
  • Rye straw
  • Buckwheat Straw
  • Corn stalks
  • Cotton straw
  • Alfalfa straw
  • Other kinds of straw

Technical Principle of Straw Charcoal Machine

Pyrolysis technology is the core principle of straw charcoal making machine. Pyrolysis refers to the thermal decomposition of organic materials in a low-oxygen environment. Through pyrolysis, the straw can be converted into charcoal, wood vinegar, tar, and syngas. The general process of pyrolysis is as follows:

  1. Pretreatment: Ensure that the moisture and size of the straws meet the feeding requirements (moisture≤15%, size≤20mm).
  2. Feeding: Transport the straws to the pyrolysis reactor by the conveyor.
  3. Pyrolysis: At 150 ℃, some of the raw materials start to decompose into CO, CO2, etc. At 350 ℃, charcoal appears continuously. Typically, the reaction takes approximately 15-25 minutes.
  4. Syngas recycling: After about 30 minutes, a lot of biogas will be generated. It will return to the combustor to heat the reactor.
  5. Cooling discharging: Charcoal, will be cooled and discharged until its temperature is reduced to below 45 ° C.
  6. Dedusting: The dedusting system (cyclone dust remover, spray dust collector, etc.) will remove harmful components such as sulfur from the biogas.

How Can You Profit Straw Charcoal?

Straw charcoal has wide applications, which brings good investment prospects for investors. If you are considering straw to charcoal project, you may make a profit from these ways in the future:

  • Sell straw charcoal to practitioners involved in soil remediation or improvement projects, or big farms.
  • Sell straw biochar to practitioners involved in carbon neutral, carbon sink, and carbon credits.
  • Sell straw charcoal to practitioners in the catering industry, especially BBQ market.
  • Sell straw biochar to hookah charcoal manufacturers.
  • Sell straw charcoal to feed manufacturers or livestock farms. Here straw biochar will be used as feed additives to adjust animals’ intestinal health.
  • Sell straw charcoal to metal smelting factory. Here straw charcoal plays the role of a metallurgical reducing agent.
  • Sell straw charcoal to factories like cement plants, boiler plants, power plants, ceramic plants, etc. Here straw charcoal is used as fuel.
