R1, R3, R10 and D10: how the Waste Act classifies recovery and disposal
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: loading the digester with organic load — how to calculate and choose
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.
China: amendment to the solid waste law adopted on 29 April 2020. It takes effect on 1 September
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 introduces mandatory waste sorting from 1 May 2020. Four categories and fines for businesses
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.

France adopts the PPE: 14–22 TWh of biomethane injected into the grid in 2028
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.
Gas for Climate: gas decarbonisation pathways to 2050 and a proposal for 10% renewable gases in 2030
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 in biogas upgrading: operating principle and water balance
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.
The Commission publishes guidelines for waste management during the COVID-19 pandemic
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 or digestion of biowaste? A comparison of process, law and odour
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.

Vietnam: Decision 08/2020 — biomass tariff of 7.03 and 8.47 USD cents/kWh
Decision 08/2020/QD-TTg raises the Vietnamese biomass tariff: 7.03 USD cents/kWh for cogeneration and 8.47 cents for non-CHP sources, for 20 years from commissioning. It enters into force on 25 April 2020.
IEA on biogas and biomethane: potential to cover approx. 20% of global gas demand
The IEA special report "Outlook for biogas and biomethane: Prospects for organic growth" estimates that full use of the sustainable potential could cover about one fifth of global gas demand.
Waste pyrolysis: the state of the technology, products, limitations and a realistic assessment
Pyrolysis is the thermal decomposition of waste without oxygen into gas, oil and char. We show the types of process, the product balance, the barriers to scaling up and what to realistically expect from the technology.
Hazer and Water Corporation: ARENA supports biogas from wastewater as a source of hydrogen and graphite
In 2019 ARENA announced up to 9.41 million AUD for Hazer Group for a demonstration plant at the Woodman Point treatment plant (Perth), which is to produce hydrogen and graphite from biogas.
