The traditional use of biomass is still the reality in the world. In 2019 the traditional use of biomass represented 6.5% in total final energy consumption and the modern bioenergy was 5.1% in the world. The modern use of biomass involves the use of advanced and efficient technological processes such as liquid biofuels, production of briquettes and...

The growth of the economy in urban centers is invariably accompanied by an increase in human activities and environmental interference, mainly related to waste generation. Due to the nature of these activities, large volumes of varied waste are generated daily without the establishment of compatible and adequate collection, logistics, and final dis...

Anaerobic digestion (AD) is a multipurpose technology. One of the AD outcomes is biogas that can be used to supply a local thermal demand, electricity generation or upgraded to fuel vehicle. Brazil has the largest potential for producing biogas, due to its extensive agroindustrial production plus the fact that the country has a population of over 2...

Diversifying the energy components of a country's transport sector is essential to guarantee the fuel supply to consumers and increase the market dynamics and competitiveness. Among the known alternative fuels, biogas is a renewable source and after upgrading to biomethane, it presents a similar composition to natural gas (>90% of CH4; 35–40 MJ.m⁻³...

Despite the importance of its natural environment and of its agribusiness sector, Brazil is a largely urbanised country, but unfortunately with significant inequalities. In several cities, mainly in the North (N) and Northeast (NE) administrative regions, there are the shantytowns (favelas), lacking basic sanitation, differently from Southeast (SE)...

Addressing climate change requires rapid greenhouse gas (GHG) emissions reductions, which can be achieved by shifting the energy system from fossil fuels to low-carbon, renewable sources. Furthermore, stabilising global temperatures demands net-zero emissions of long-lived GHGs. To achieve a carbon-neutral world, negative emissions technologies (NE...

Mato Grosso is a leading state in Brazil’s thriving agribusiness, both in crop and livestock production. However, it is also the second state in Amazon deforestation. Biomat Project was set up to identify the situation of bioenergy and opportunities for sustainably expanding its production and use in the state. An important finding was the possibil...

The lack of access to clean fuels and efficient technologies for cooking profoundly affects the individual’s living and social conditions, causing serious impacts on health, education and economic development.
