Biomass refers to any organic material derived from plants and animals that can be used as a source of energy. It is generally classified into three primary categories: woody biomass, non-woody biomass, and animal waste. Woody biomass includes materials obtained from forests and plantations, while non-woody biomass comprises crop residues, processing by-products, as well as aquatic, food, and domestic waste. Animal waste consists of by-products from animals raised for meat, milk, and other products.
NIR Spectroscopy as a Tool for Biomass Screening
NIR spectroscopy is a useful tool for the rapid screening and assessment of biomass. It is fast and non-invasive and minimal to no sample preparation is required. The technique is far less labor-intensive than traditional methods and no toxic chemicals or solvents are needed, making the method a potent green tool with the potential to play a pivotal role in renewable energy and sustainable resource management.
NIR spectroscopy uses advanced multivariate chemometric techniques for qualitative analysis and sample classification. Comprehensive results on biomass composition can be obtained, including proximate analysis, cellulose, hemicellulose, lignin, extractives as well as complex characteristics such as freshness, biogas potential, and calorific value.
Fast characterization of biomass is crucial for the development of new bioenergy crops and optimization of conversion processes like bioethanol production, biogas generation, and combustion in biomass power plants.
Most important of all, NIR spectroscopy can determine values for multiple chemical and physical parameters of interest from a single measurement. Advances in modeling techniques, instrument portability, cloud-based systems, and instrument hardware have facilitated the use of NIR spectrometers for both field use and on-line process monitoring of biomass.
