Biomass Energy
Biomass can also be co-fired, or burned with a fossil fuel. Biomass is most often co-fired in coal plants. Co-firing eliminates the need for new factories for processing biomass. Co-firing also eases the demand for coal. This reduces the amount of carbon dioxide and other greenhouse gases released by burning fossil fuels.

A review of biomass co-firing in North America
As shown in Fig. 1, in direct co-firing technology biomass is fed directly into the furnace after either being milled together with the base fuel ( Fig. 1 a) or being milled separately ( Fig. 1 b) [17]. The fuel mixture is then burned in the burner. The co-firing rate is usually in the range of 3–5%.

Biomass Co-firing in Coal Power Plants
PROCESS AND TECHNOLOGY STATUS. Biomass co-firing consists of burning biomass along with fossil fuels in coal- and gas–fired power plants. (ETSAP E01, E02). This brief deals with biomass co-firing in coal power plants, which is by far more widespread and extensively proven than biomass co-firing in gas-fired plants1.

Laying the foundation for zero-carbon cement
Cement acts as the binder between aggregates (fine and coarse rocks) in the formation of concrete. While cement makes up only a small percentage of the mix (approximately 12 percent by volume), it is almost exclusively responsible for the resulting CO 2 emissions. In the cement-manufacturing process, raw materials are heated to high …
