Biomass
Introduction
Biomass is organic matter derived from living or recently living organisms.
Examples include wood, crop residues, organic waste or algae. All biomass consists of fibres bound in a combination of carbon, hydrogen and oxygen. The specific composition is key to the quality of biochar that can be produced.
In this module, we will discuss the various properties of biomass and highlight the distinction between fossil and renewable resources. Understanding these differences is crucial, as they play a significant role in the production of biochar and its potential applications. This overview will lay the groundwork for a deeper understanding of biomass and its importance in sustainable practices.
TASKS
Different types of biomass: Sort the types of biomass into the two categories.
Are the following statements true or false?
BIOCHAR CHAIN
In this section, we will explore the biochar chain, a complex network of stakeholders involved in the production of biochar from biomass. Each participant plays a crucial role in this process, contributing to the transformation of raw materials into valuable products. It is important to note that stakeholders may fulfill multiple roles, emphasising the interconnectedness of the biochar chain. From a circular economy perspective, the last group can also become the first, further illustrating the dynamic relationships within this system. As we examine this chain, we will set the stage for a deeper dive into the specific actors and their contributions, which will be presented in the accompanying video.
TASKS
- Do you belong to one/several of these groups?
- Which stakeholders do you know and could be interesting as collaboration partners?
- Who are biomass producers/owners in your region?
BIOMASS SOURCES & PROPERTIES
In this exercise unit, we will focus on the various sources of biomass and their specific properties that are relevant for pyrolysis and the quality of the resulting biochar. It is crucial to understand that not all biomass types are equally suitable for this process. Each type of biomass must first be harvested and the preparation effort can vary significantly. Depending on which biomasses are increasingly used for the production of biochar in the future, this will not only have an impact on the pricing of the biomass market, but also on the landscape. It is up to us to think about the effects on biodiversity through the design of the landscape. Given the increasing competition for raw materials such as wood chips, it is essential to examine the different biomass sources in detail. Let us explore the diversity of biomass together and analyse its potential for sustainable biochar production!
TASKS
- Please list the biochar producers and sources that might be relevant in your case
- How do you estimate the potential of residual (waste) biomass in your region?
- What are the most important properties biomass should have to produce biochar in your use cases?
BIOMASS Preparation
Biomass preparation is a critical step in the biochar production process, as it directly influences the efficiency and quality of the final product. This phase involves various activities, including the collection, sorting, and processing of biomass to ensure it is suitable for conversion. Proper preparation not only enhances the physical and chemical properties of the resulting biochar but also optimises the pyrolysis process. In this section, we will examine the key methods and techniques used in biomass preparation, as well as the factors that impact its effectiveness. Understanding these elements is essential for maximising the potential of biochar for the market.
TASKS
- Which pre-treatments support the conversion biomass into biochar through pyrolysis? (Musterlösung)
- Which preparation step do you consider necessary in your case (maybe table with different input materials and pathway)?
Local/Regional Investigations on Residual Biomass
Understanding the availability and characteristics of residual biomass at local and regional levels is essential for effective biochar production and sustainable resource management. This section will focus on the significance of conducting investigations into residual biomass sources, which include agricultural by-products, forestry residues, and organic waste from various industries. By examining these local resources, we can identify opportunities for utilising biomass that might otherwise go to waste. Additionally, these investigations help assess the potential environmental and economic benefits of converting residual biomass into biochar. As we explore this topic, we will highlight the importance of community engagement and collaboration in harnessing local biomass resources for sustainable practices.
