January 4, 2018 – A report issued by Canada’s National Energy Board shows that the country’s non-hydro renewable power capacity grew by more than 8 percent in 2016, adding nearly 1,300 MW of solar, biomass and wind-generated power. According to the NEB’s report, Canada’s electricity generation was 66 percent renewable in 2016, with non-hydro renewables accounting for 7.2 percent and hydro accounting for 58.8 percent. Canadian biomass capacity increased by 288 MW between 2015 and 2016, reaching 2,702 MW and accounting for 1.8 percent of total capacity in the country. Biomass generation also increased over the same time period, reaching 13,214 gigawatt hours (GWh) in 2016, up from 12,511 GWh in 2015.
January 4, 2018 – Connecticut’s Department of Environmental Protection has selected the Sacyr Rooney Recovery Team to redevelop Hartford’s Materials Innovation and Recycle Authority (MIRA) waste-to-energy facility, as reported by the Hartford Courant. The team comprises the Spanish company Sacry, Manhattan Construction Group, Synagro and CWPM. The plan calls for recycling an estimated 40% of incoming waste, either through anaerobic digestion, composting or enhanced recycling technologies.
January 5, 2018 – Tanga — As the about 500,000 hectares of forest are estimated to be lost every year a university don has said that Tanzania could offset such a threat by utilising its big potential in biogas. Speaking at the Final Evaluation Workshop of the World Wildlife Fund (WWF) Tanzania Country Office three year Energy Programme, Prof Siza Tumbo has said that if Tanzanians decide to fully utilise the present of a large number cattle to build biogas digesters, it could have a positive effect, not only in saving forests but also in spurring growth in the establishment of biogas companies.
January 5, 2018 – Double crops, agricultural techniques characterised by minimum tillage, fertirrigation and natural soil enrichment methods: farms that follow the production strategy promoted by CIB’s (Italian Biogas Consortium) Biogasfattobene model (“Biogasdoneright”) not only improve the levels of biodiversity, quality and soil nutrients, but can also become “carbon negative”. Technologies used in biogas plants can indeed actively capture carbon (in the form of cultivated additional biomass) and store it in the soil through the use of digestates such as bio-fertilizer, thus accumulating more CO2 than produced.
January 5, 2018 – To confront global warming, climate changes and a potential energy shortage, biodiesel received increasing interest as a substitute for diesel fuels in efforts towards sustainable development. Microalgae-derived biodiesel is a promising energy source. The advantages of microalgae as a biodiesel feedstock are many, for example, efficient photosynthesis, high lipid content, efficient CO2 mitigation, noncompetition for farmland, toleration to wastewaters during the growth, less water footprint and more cost-effective farming than energy crops.
January 8, 2018 – In a paper by Texas A&M scientists, biochar shows potential for increasing efficiency of the anaerobic digestion of animal manure. Biochar is a charcoal material composed of agricultural by-products, including manure, crop residues and grasses. The substance can be used as a fertiliser and as a filter to remove contaminants from water and wastewater, including antibiotics, pesticides and hormones; in the process, biochar captures CO2 and ammonia.
January 9, 2018 – It’s beyond doubt: biogas will remain a key player in the German market for a long time to come. It’s essential, however, to aim for “flexible biogas” by renovating existing plants and enabling them to increase or reduce their energy production to adapt to the volatility of the market. Daniel Holder explains that flexibility is a valuable resource in modern energy markets, in which production quotas will increasingly depend on non-programmable renewable sources.
January 9, 2018 – Green gas can make a key contribution to meeting the goals set out in Scotland’s first ever Energy Strategy, according to the UK’s trade body for anaerobic digestion. Charlotte Morton, Chief Executive of the Anaerobic Digestion & Bioresources Association (ADBA), said, “The Scottish Government has set itself ambitious but necessary targets for generating renewable energy in its new Energy Strategy, and renewable heat and electricity produced through AD can make an important contribution to these goals, as well as reducing emissions from landfill, creating rural jobs, and helping to restore degraded soils.”
January 9, 2018 – The designer of ‘the world’s largest’ downdraft gasification plant has announced the issuing of approximately $21.4 million (€17.9 million) of new equity. In addition, Nashville, Tennessee based Aries Clean Energy has received additional commitments from Boston based private equity firm Spring Lane Capital of $25 million for equity in future gasification projects. According to a statement, proceeds from the offering will be used to fund project development, retire debt and other general corporate purposes.
January 9, 2018 – Each day, waste industry workers perform vital functions that keep cities clean and communities healthy. Most of those functions remain fundamentally the same year-to-year: collect material, sort it, recover value and dispose of the rest. And yet, there are shifts each year that change how the industry operates. Composting, glass recycling and the increasing use of compressed natural gas (CNG) helped shape 2016. In 2017, the conversations that moved the industry ranged from China’s ongoing policy changes to how the big companies in the industry responded to natural disasters.
