At the end of February, EU member states and the European Parliament reached a consensus: both the Renewable Energy Directive and the Fuel Quality Directive will incorporate sustainability criteria for biofuels. A dedicated working group has been formed, and a draft is expected to be submitted by June. This agreement marks a significant breakthrough in resolving a long-standing deadlock that had stalled the revision of the Fuel Quality Directive, advancing the EU’s efforts to promote sustainable biofuel development.
According to reports, if stricter sustainability standards are approved, the EU may ban biofuels sourced from tropical rainforests, wetlands, and grasslands. This could severely impact the biofuel industry in Southeast Asia, where many of these crops are produced.
Earlier, the UN Energy Agency had called for an international biomass certification system to ensure all biofuels meet environmental standards. The EU’s push for sustainable biofuel policies may encourage other major fuel-consuming nations to reassess their own biofuel strategies.
A year ago, the European Commission passed new legislation aiming to revise the Fuel Quality Directive and establish more rigorous environmental standards for fuel production and transport. The goal is to reduce greenhouse gas emissions and accelerate the transition to a low-carbon economy. The proposal requires fuel suppliers to cut emissions by 10% by 2020, equivalent to 500 million tons of CO₂—roughly the total emissions of Spain and Sweden combined.
Biofuels have the potential to replace fossil fuels and lower greenhouse gas emissions. Crops can also absorb COâ‚‚ during growth. However, experts warn that burning biofuels releases the same gases back into the atmosphere, potentially contributing to global warming. Additionally, the rapid expansion of biofuel production has raised concerns about land use, water scarcity, and rising food prices due to agricultural instability.
The Royal Society suggests that using biofuels alone won’t significantly reduce CO₂ emissions unless specific measures are taken. EU countries argue that sustainability criteria should be included in the Fuel Quality Directive to prevent manufacturers from focusing solely on cost-effective CO₂ reduction without considering broader environmental impacts.
However, the European Commission claims that sustainability standards are already included in the Renewable Energy Directive. As a result, they believe there is no need to repeat them in the revised Fuel Quality Directive. This led to a stalemate between the two sides.
Now, the impasse has been resolved. EU member state officials have formed a working group to develop “core guidelines†for sustainable biofuel development, which will be incorporated into the two directives in different forms.
Despite this progress, defining what constitutes a sustainable biofuel remains a contentious issue. John Pickett from Rothamsted Research emphasized that greenhouse gas emissions depend on how crops are grown, processed, and used. Simply increasing biofuel use without careful planning might not yield the best emission reductions.
Dorette Corbey, a member of the European Parliament’s drafting team, noted that the introduction of these directives provides strong incentives for biofuel development. However, since the European Commission hasn’t yet shared its sustainability criteria, the Parliament has no choice but to provide general guidance.
Pulverizer Machine
Pulverizers are machines that pulverize large solid materials to the required size.
According to the size of the crushed material or the crushed material, the mill can be divided into coarse crusher, medium crusher, fine mill and superfine mill. There are four kinds of external forces applied to the solid in the grinding process: pressing, cutting, impact and grinding. Press rolling is mainly used in coarse and medium crushing, suitable for the crushing of hard materials and bulk materials. Shearing is mainly used in fine crushing, suitable for the crushing of ductile materials. Impact is mainly used in medium crushing, fine grinding, ultrafine grinding, suitable for crushing brittle materials. Grinding mainly in fine grinding, ultrafine grinding, suitable for small pieces and fine particles.
The crusher makes use of the high speed relative motion of the movable tooth plate and the fixed tooth plate, so that the crushed object can be crushed by the comprehensive action of tooth impact, friction and the impact between the materials. The crusher is suitable for crushing Chinese herbs, precious medicinal materials, ores and chemical raw materials in small batches in various varieties, alloys, metallurgy, geology, scientific research and other units.
The pulverizer machine has the advantages of simple structure, solid, stable operation and good crushing effect. The pulverized material can be discharged directly from the grinding chamber of the main machine. The particle size can be obtained by replacing the mesh screen with different aperture. The powder collecting chamber adopts the completely closed silencer structure, which can effectively reduce the working noise. In addition the machine is all stainless steel. The inner wall of the casing is machined to achieve smooth surface, which changes the phenomenon of rough inner wall and powder accumulation of the previous models, so that the production of drugs, food, chemical industry and so on is more in line with national standards and meet the requirements of GMP.
