RDF is a fuel from the high-calorific fraction of waste, SRF its standardised, better-described variety. We explain codes 19 12 10 and 19 12 12, classification by standard and who buys such fuel.
Cryogenics separates CO₂ by cooling biogas to very low temperatures. We explain why the technology is linked to the production of bioLNG and liquid CO₂ and what limitations it has.
On 22 June 2020 Regulation (EU) 2020/852 was published, introducing a classification of environmentally sustainable activities and six environmental objectives.
Indonesia has hundreds of palm oil mills, but in 2014–2018 biogas from POME was used on a small scale. What were the barriers: tariffs, grid connections, experience with PLN contracts and financing?
The Municipal District Heating Company (MPEC) in Tarnów will build for PLN 200 million a cogeneration installation based on waste-derived fuel. Co-financing from the National Fund for Environmental Protection and Water Management (NFOŚiGW) is around PLN 165 million.
HRT is the residence time of the liquid, SRT — the residence time of the microorganisms. In a flow-through digester they are equal, in systems with recirculation they are not.
On 10 June 2020 the German federal government approved a hydrogen strategy with a target of 5 GW of electrolyser capacity by 2030 and a budget of EUR 9 billion, of which EUR 7 billion domestically.
Since the 2008 energy agreement, Denmark has paid a premium of 40.5 øre/kWh or a fixed price of 74.5 øre/kWh for electricity from biogas. In 2013 a value of 79.3 øre/kWh appeared in legislation.
The company H. Cegielski-Poznań holds a licence to produce Dynamic Biogas plants. A 0.5 MW pilot is operating at the experimental farm of the Poznań University of Life Sciences in Przybroda.
On 27 May 2020 the Commission proposed a post-pandemic recovery fund: EUR 750 billion, of which EUR 500 billion in grants and EUR 250 billion in loans, combined with a strengthened EU budget for 2021–2027.
A report of the REGATRACE project, whose renewable gas work was coordinated by the EBA, compared biomethane markets in Europe: from 10 TWh in Germany to approx. 1.2 TWh in France.
The European Commission has approved the Danish scheme SA.55891: DKK 4.15 billion (about €550 million) for existing biomass power plants, with a premium of up to DKK 0.11/kWh, until the end of 2029.
Communication COM(2020) 381 announces a reduction of nutrient losses by at least half and a 20% cut in fertiliser use by 2030. This matters for digestate and manure management.
Chemical absorption in amines gives methane losses below approx. 0.1–0.2% and pure CO₂, but requires heat of approx. 110–140°C. We discuss the energy balance and operating requirements.
Rwandan prisons are among the pioneers of biogas in Africa: from 2008 to 2011 the number of institutions with biogas rose from eight to fourteen. Why do such installations differ in effectiveness?
The R and D symbols from Annexes 1 and 2 to the Waste Act end up in the permit and in reports. We explain what R1, R3, R10 and D10 are, and where fermentation and the use of digestate fit in.
OLR is the mass of volatile solids fed per m³ of digester per day. We show the formula, a worked example, typical ranges and the effects of overloading.
On 29 April 2020 the Standing Committee of the National People's Congress adopted an amendment to the law on preventing solid waste pollution: waste sorting, higher fines, plastic restrictions.
Beijing has joined the cities with mandatory waste sorting. Residents divide waste into kitchen, recyclable, hazardous and residual, and violations can cost from 50 to 50,000 yuan.
Decree 2020-456 of 21 April 2020 set the French multiannual energy programme. The target for injected biomethane: 6 TWh in 2023 and 14–22 TWh in 2028.
The Gas for Climate consortium published a Guidehouse study according to which biomethane and hydrogen in the existing infrastructure can reduce transition costs by more than EUR 200 billion per year.
Water scrubbing removes CO₂ thanks to its good solubility in water under pressure. We describe the absorption and desorption columns, the water balance, methane losses and limitations.
On 14 April 2020 the EC issued guidelines intended to ensure the continuity of waste collection and treatment during the epidemic, in line with EU waste law.
Composting is aerobic and yields compost; digestion is anaerobic and yields biogas and digestate. We compare the two processes in terms of law, animal by-products (UPPZ), the end product and odour nuisance.
