New year sees a resurgence for straw
A series of deals involving straw in January highlighted the feedstock’s environmental and cost benefits. In total, five projects which have a connection to straw-fired heat and power moved forward, compared to an average of just two per month in 2017, according to EWB’s database.
One of the deals saw Denmark-based Linka secure a contract to build a new straw-fired heating plant from utility company Mørke Fjernvarme for an undisclosed fee.
The facility, which will be built in Mørke, to the north of Aarhus, will have a capacity of 4.5MWth. The utility company currently has a wood-fired plant, which was also supplied by Linka, but demand for the facility’s heat is being "overloaded" and the new plant is needed as a replacement.
However, Linka also points out that the shift from wood pellets to straw will lead to a "reduction in fuel and operating costs" and reduce CO2 emissions by 909 tonnes over the next 20 years.
Dutch bioenergy plant builder Host also saw the benefits of straw-fired power and heat. It bought Poland-based rival Eurobiomass for an undisclosed fee.
The deal sees Host take over a business with a history of building straw and woodchip-fired facilities dating back to 1996. According to Eurobiomass’s website, the plant builder has delivered 21 straw-fired facilities and 37 woodchip-fired ones.
China-based DP Cleantech also won a contract to overhaul a straw-fired cogeneration plant which had experienced "operational problems" relating to boiler availability, stability and several other issues.
The plant, which is located in Elblag, Poland, and opened in 2014 is owned by utility company Energa Kogeneracja. It will get a new combustion system, including feeding system, grate, grate drive and slag conveyor. The 24MW plant can supply around 220GWh of steam for district heating a year.
In the UK, GMT Biogas submitted new plans for an anaerobic digestion plant after its first application was turned down. Crucially, it will now process straw in place of animal slurry and will not use "any waste materials". The plant, which will in total process 19,250 tonnes per year of biomass, will use more than 7,000t of straw per year.
The application is due to be decided later this year.
Lastly, UK-based investment fund Glennmont says it will target "to-be-built and recently operational assets" as it unveiled plans for a third fund. The refinancing of its 40MWe Sleaford straw-fired plant and its 245MWe Italy-based wind portfolio last year, has allowed it to look for new investments.
The European Parliament’s vote in favour of a 35% renewable energy target for 2021-2030 for the second Renewable Energy Directive, known as RED II, was a boost for bioenergy. MEPs voted down stricter biomass sustainability proposals and refused to introduce harsher rules for the co-firing of biomass in coal-fired power plants. The Brussels-based Confederation of European Forest Owners (CEPF) hailed the vote as a "positive" move for Europe’s bioenergy sector. However, CEPF further called for the criteria for biomass-to-energy to be simplified as talks move on.
Crucially MEPs, while banning palm oil from biofuels also "left room" for a percentage of crop-based biofuels by introducing a 12% target for renewables in transport, according to bioethanol trade body ePure. MEPs also rejected a phase-down of crop-based biofuels in favour of a freeze at the current level of 7%.
UK-based majority biomass-fired power plant Drax will convert a fourth boiler to fire on biomass following the government publishing its consultation into financial support under its Renewable Obligation scheme. The government ruled that power plants will be able to "optimise generation across units and decide whether they use a single unit or more than one unit to generate up to the level of their station cap".
EU statistical office Eurostat reported the percentage of municipal waste sent for energy recovery plateaued at 27% between 2014 and 2016, indicating a "positive trend" according to the EfW sector. Recycling facilities and landfills in 2014 both took 28% of municipal waste produced with a further 16% going to composting facilities. However, by 2016 the amount recycled had risen by two percentage points to 30% while the amount landfilled had dropped by three percentage points to 25%.
EfW trade association ESWET said the European Commission’s proposal to "gradually increase fees and taxes" for energy recovery will not boost plastic recycling. ESWET believes the proposals will mean plastics that cannot be recycled will end up in landfills rather than being turned into useful energy.
The UK’s biogas sector faces an uncertain future due to "unjustified" increases in charges by England’s Environment Agency (EA), according to trade body Anaerobic Digestion and Bioresources Association (ADBA). The EA, which recently consulted on the proposals, has previously said that its current charges do not "fully cover the cost" of its activities. However, ADBA said in "some cases the increases will double the existing charge", while even small cost increases could "result in greater strain" and "have a detrimental impact" on the sector.
The UK government published a long-awaited response to its consultation into overhauling the non-domestic renewable heat incentive (RHI). The response took away funding for drying of certain wood-fuels (when not replacing fossil fuels) and of waste, but retained the drying of "other, non-woody" biomass as an eligible heat use. ADBA said the government now "urgently" needs to pass legislation that will guarantee higher tariff levels for renewable heat generation and restore confidence to the sector.
The Danish government made DKK25m (€3.3m) of support available for the development of biorefineries, with the hope the facilities would be built "throughout the country".
The UK government launched a technical consultation on a draft version of the secondary legislation required to bring into force its plans to extend landfill tax to cover material disposed of at illegal waste sites. The first of the changes would mean rogue operators caught handling waste illegally would be forced to pay landfill tax.
German-based trade associations and biogas businesses urged the country’s next government to move quickly to cut the country’s use of coal for electricity and boost its biogas infrastructure. A joint statement urged the "sustainable retrofitting of existing biogas plants" instead of supporting coal or "fluctuating" renewables such as solar and wind power.
Increasing Scottish biomethane production could make an "important contribution" to renewable heat targets, according to the Scottish Energy Strategy. Currently, Scotland produces 90% of its renewable heat from burning biomass, while there are just 13 biomethane sites in Scotland connected to the gas grid – although more are in the pipeline.
The UK government plans to bring forward legislation to make coal-fired power stations subject to a new emissions intensity limit as part of plans to end unabated coal generation in Britain by 2025.
The House of Commons’ Environmental Audit Committee called for a 25p recycling charge to be added to every disposable cup sold in coffee shops in the UK in a bid to achieve 100% recycling of coffee cups by 2023. The move has been branded as the "latte levy".
The UK’s House of Lords raised concerns about the UK’s export of waste to Europe after Brexit. It urged the government "to preserve non-tariff, barrier-free trade to the greatest extent possible" for waste as a "lack of clarity over the UK's future policy direction" is a big concern for the waste sector, which has left it "unable to plan" for new business or to make investment decisions, according to the committee.
France-based Suez plans to develop what is says will be Europe’s first facility recovering non-ferrous metals from incinerator bottom ash (IBA) in the port area of Ghent, Belgium. Suez has been working on the project since November 2015, with a pilot-scale facility proving the concept works. The company says it hopes to recover up to 12,000t/yr by 2019 from IBA sourced from European countries such as Belgium, France, the UK and Poland.
Canada-based Enerkem and China-based Sinobioway Group will work on the construction of the 100-plus biofuel-from-waste facilities in China by 2035. So far Enerkem has developed its technology in Canada, becoming the first company to commercially produce bioethanol from waste. It has also been developing a facility in Rotterdam in the Netherlands.
Estonia-based Graanul Invest started moving wood pellets on the open seas itself after launching its first ship, the MV Imavere. The ship, named after the company’s first pellet-making plant in Imavere, can carry about 30,000 tonnes of biomass per voyage.
A draft minerals and waste plan from UK local authority Surrey County Council revealed the municipality is facing large gaps in its treatment capacity for waste through energy recovery and biogas. Surrey is facing an energy-recovery gap of 174,00-278,000t/yr by 2033, while other forms of recovery, which includes biogas production, face a capacity gap of 44,000-116,000t/yr.
Finland-based Fortum launched a tender for flue gas equipment services for a number of its facilities in the Stockholm area. The tender covers plants including the part waste-fired Högdalen, the part biomass-fired Hässelby and the soley biomass and waste-fired Brista facility.
