The NDRC and the construction ministry presented a municipal waste infrastructure plan for 2021–2025: incineration capacity of 800,000 t a day and about 60% material utilisation of household waste.
The International Energy Agency's "Net Zero by 2050" report describes the path to neutrality in the energy sector: no new oil and gas fields and a four times faster pace of wind and solar additions.
Communication COM(2021) 400 brings together EU targets on air, water, soil and waste. It assumes, among other things, a 50% reduction in nutrient losses and halving residual municipal waste by 2030.
On 20 April 2021 Serbia adopted a renewables act: a market premium awarded in auctions for 15 years, with tariffs only for small sources. Until now biogas had about 17 eurocents/kWh.
The UNEP and Climate and Clean Air Coalition report of 6 May 2021 estimates that reducing anthropogenic methane emissions by about 45% by 2030 will avoid almost 0.3°C of warming by 2045.
Orlen Południe and the Polish Oil and Gas Company (PGNiG) signed a letter of intent on a network of biomethane plants. The investments are to be carried out by a special purpose company in which Orlen Południe will take 51% of the shares and PGNiG 49%.
On 29 April 2021 China's parliament passed a law against food waste: obligations for restaurants, fines for misleading customers and the possibility of charges for leftovers.
The government sent the National Recovery Plan to Brussels. The March 2021 draft envisaged, among other things, EUR 437 million for offshore wind, EUR 97 million for energy communities and investment in hydrogen.
The Polish Development Fund (PFR) provided mezzanine financing to the ITPO Olsztyn project: an installation with a throughput of at least 100 thousand tonnes per year, which is to supply the district heating network and replace a coal-fired source.
Landfill gas forms from the decomposition of biodegradable waste and usually contains about half methane. We describe the phases of its formation, composition, risks and the degassing obligations under the directive and national rules.
Pumping slurry, digester slurry and digestate is a job for several types of pump. We compare features, applications, wear and typical failures.
Biomethane is settled on the basis of energy: a gas meter measures the volume and a chromatograph the calorific value. We describe the metering system, propane for calorific correction and quality supervision.
On 21 April 2021, the Commission presented the taxonomy criteria for climate objectives. They cover, among others, biogas production, digestion of biowaste and sewage sludge, and landfill gas capture.
The European Parliament and the Council agreed on 21 April 2021 the text of the climate law: binding neutrality in 2050, a 55% net target by 2030 and a limit of 225 Mt CO₂ on the contribution of removals.
The ABPP programme (SNV, Hivos and the Dutch Ministry of Foreign Affairs) covered Ethiopia, Kenya, Tanzania, Uganda and Burkina Faso. The figures given by the organisers differ; we explain what follows from them.
The Council of Ministers adopted a draft amendment to the RES Act extending the auction system to the end of 2027 and FIT/FIP to mid-2024, and raising the licence threshold from 0.5 to 1 MW.
Mixing determines homogeneity and the distribution of sediments and scum. We compare submersible, central and long-shaft mixers, and the criteria for selection, energy use and servicing.
Gas in the grid must smell so that a leak can be detected. We explain what biomethane is odorised with, where, and in what dose, and how the odorant affects sulphur measurement.
Orlen bought 70.15% of the shares in CHP Energia, the owner of a 1.2 MWe biogas plant in the Podlaskie region. The sale agreement was signed on 18 March 2021, after the purchase of the biogas plant in Konopnica.
A biogas plant receiving waste must operate in BDO: register entry, records and a KPO for deliveries, and every year a waste report by 15 March. Check who this applies to and what to do.
The Estonian scheme gives a premium of up to €53.7/MWh for 12 years. It declines when the market price exceeds €39.3/MWh and disappears at €93/MWh. Since 2019, auctions have competed for support for biogas plants.
The Romanian green certificate system (Law 220/2008) rewards electricity from biomass and biogas. The certificate price corridor is EUR 29.4–35, and the scheme has been closed to new participants since 2017.
METI and NEDO launched a Green Innovation Fund worth 2 trillion yen, which supports hydrogen among other things: up to 300 billion yen for the supply chain, 70 billion for electrolysis and 193.5 billion for hydrogen in steelmaking.
How to start a new or emptied digester: filling, inoculum, gradual heating, gas control and a safe path to the full feed rate over weeks.
