Prospects of sustainable feedstock production for advanced biofuels. Hans van...Oleksandra Tryboi
Presentation gives an overview of sugar beet as a biobased crop that is ideal for farmers to grow. Sugar beet is a strategic food, feed and energy crop, essential in crop rotation program, giving better results, compared to other crops, by improvement of soil fertility and soil structure and has low water footprint. Production of EtOH from sugar beet need less water and is more efficient compared to such feedstock as corn stover, poplar, miscanthus and corn.

Machine Converting Waste Plastics into OilPrasanna Datar
Homogenization of waste plastic is the method to restore to oil heating and
dismantling used plastics through reverse process of producing plastic products in
Petro-chemistry industry.
Thermal decomposition with low temperature is endothermic reaction system
heating wastes indirectly with low temperature (350℃ ~ 450℃) under no oxygen or low
oxygen environment and forms unstable radicals with weak linked part being
cut first and similar linkage systems being combined randomly and cut.
It consists mainly of radical reactions. Cut-off situation of combination happens
successively with energy being transferred into combined structure of organic matter
through continuous reactions, changes to substance with tiny molecular weight and
through this process clean fuel with prominent value is created as environment-friendly
resource for less generation of contaminants.

A TEXT BOOK : Complete and comprehensive inputs in Learning about Biogas and Biogas digestors:We have tried to take the mystery away from biogas.
Biogas is a renewable energy source with many different production pathways and various excellent opportunities to use.
One main advantage of biogas is the waste reduction potential. Biogas production by anaerobic digestion is popular for treating biodegradable waste because valuable fuel can be produced while destroying disease-causing pathogens and reducing the volume of disposed waste products.
Biogas burns more cleanly than coal, and emits less carbon dioxide per unit of energy. The carbon in biogas was recently extracted from the atmosphere by photosynthetic plants. Releasing it back into the atmosphere adds less total atmospheric carbon than burning fossil fuels.
Thus, biogas production kills two birds with one stone: it reduces waste and produces energy. In addition, the residues from the digestation process can be used as high quality fertilizer. This closes the nutrient cycle.
Supercritical fluid dyeing with carbon dioxideMD. JAKIR HOSEN
In order to minimize greenhouse gases, hazardous wastes and for safe conditions the idea of SCF is important. And this is about Supercritical Fluid Dyeing (SCFD) with Carbon Dioxide.
Sludge2Energy: Energy self-sustaining sewage sludge utilisation processA.T.E. Private Limited
Increasing sludge production and stringent sludge disposal norms have forced many municipal organisations and sludge disposal companies to look for alternatives for sludge disposal and solutions to recover nutrients. The Sludge2Energy system safely treats and disposes sludge and recovers useful nutrients with zero net energy addition. Click on the link below to learn more.

Effective and efficient removal of hydrogen sulfide (H2S) is an essential step when sweetening gas for downstream processes. By simultaneously turning the captured hydrogen sulfide into elemental sulfur, a Frames THIOPAQ O&G system improves gas value, while creating a saleable chemical widely sought after in the agricultural and bulk chemical industry.

Russian anarchist and anti-war movement in the third year of full-scale warAntti Rautiainen
Anarchist group ANA Regensburg hosted my online-presentation on 16th of May 2024, in which I discussed tactics of anti-war activism in Russia, and reasons why the anti-war movement has not been able to make an impact to change the course of events yet. Cases of anarchists repressed for anti-war activities are presented, as well as strategies of support for political prisoners, and modest successes in supporting their struggles.

27. Establishing biogas production in the Swedish
pulp & paper industry - Concluding remarks
● Anaerobic treatment of effluents from pulp & paper mills is an alternative
to expanding aerobic wastewater treatment plants.
● Different strategies for wastewater treatment and biogas production need
to be followed depending on raw material and production process at the
specific mill
● The methane potential from an average mill is in the range of 10-50 GWh
year-1
● The total methane potential from the Swedish pulp and paper industry is
in the range of 700-1 000 GWh year-1. Of this methane potential approx.
300 GWh year-1 is located at the mechanical pulp and paper mills.
● Pulp & paper mills are located outside traditionally “substrate-rich” areas
