Global consumption of water and goods is not only draining our planet’s resources, it is also pressuring the treatment systems that ensure proper separation of harmful components and disposal of the remaining material. Treatment processes for wastewater, bio-waste and solid waste are often highly energy consuming and pose a growing expense for local governments running the treatment facilities.
There is a great potential for resource recovery and energy production within processes such as wastewater treatment and waste incineration. Harnessing this potential holds great economic incentives as the right treatment processes could create new sources of energy and help solve several challenges, including landfill pollution as well as soil and groundwater contamination.
Danish Minister: we are obligated to help countries turn growth into green growth
Yesterday, the Danish Minister for Climate, Energy and Utilities met the international press at State of Green in Copenhagen to discuss the green transition, climate ambitions and Denmark’s international role in mitigating the effects of climate change.
95 per cent of this type of plastic is not recycled: Danish companies are about to change that
New Danish partnership between companies and researchers are developing a new method of recycling plastic, which would otherwise end up incinerated or as landfill. The technology can help reduce oil consumption and CO2 emissions – and be a really good business for Danish companies.
Funding offered to partnerships focused on sustainable development
The next application round for P4G funding to partnerships with a sustainable business model is open. Funding of between USD 100,000 to USD 1,000,000 is available to either partnerships with a start-up or a scale-up concept.
Sonderborg reduced CO2 by nearly 40 per cent despite increased energy consumption
Sonderborg municipality’s total CO2 emissions have been reduced by a further 2.7 percentage points in 2018, and overall CO2 emissions have fallen by 38.3 per cent since 2007. Meanwhile, energy consumption in 2018 increased by 1.7 percentage points.
Port of Aarhus is going green: Focus on electricity from renewables
The local energy company NRGi and the Port of Aarhus are entering into a partnership that will make Aarhus more sustainable. The focal point of the agreement is green electricity from the sun and wind and the development of other energy solutions in the port.
Wastewater and seawater tested as sources for Copenhagen district heating
A new heat pump in Copenhagen will collect energy from both wastewater and seawater and test how the energy can be used in district heating. The capacity of the heat pump corresponds to district heating for 1,100 Copenhagen households.
From Coal to Biomass at Avedøre Power Station
Ramboll works innovatively with the transformation of the energy sector from fossil fuels to renewable energy. At Avedøre Power Station (in English: Avedore Power Station) in Copenhagen, Ramboll is assisting Ørsted in converting power station units from coal to biomass. The plant itself is unique in its efficient use of fuel and its ability to produce heat […]
Sludge Treatment Plant Provides Copenhagen With Clean Energy
Disposal of sludge from wastewater treatment plants in large cities is an environmental problem , however there are solutions. In Copenhagen, a new sludge incineration plant has been put into operation in 2011 at the plant Lynetten owned by BIOFOS, jointly owned by 15 municipalities in the central part of the Copenhagen region. As part of the […]
Buildings account for up to 40% of society’s energy demand and thereby play a key role in the green transition. This White Paper can be used as a tool for inspiration to spot the potential or implement building automation and energy-efficient measures in new and existing buildings globally.
From sustainable biomass to competitive bioenergy
Today, approximately 70% of renewable energy consumption in Denmark is bioenergy-based, mostly in the form of straw, wood and renewable wastes. This White Paper gives an overview of Denmark’s solutions, cases and experiences in transforming sustainable biomass resources into competitive bioenergy solutions.
ASHBACK Center for Safe Biofuel Recycling
Ash from combustion of bio-fuel in power plants contains heavy metals and is currently regarded as a waste product only to be recycled to plantations and cultivated fields in small amounts. ASHBACK aims to improve the economy of bio-fuels by enabling more ash recycling through increased knowledge about both its safety and side effects. Centre […]
Waste-to-energy CHP Vestforbraending in Copenhagen, Denmark
Vestforbraending is one of the largest waste management companies in Northern Europe. The company owns and operates a combined heat and power producing waste-to-energy plant with an annual capacity of 600,000 tonnes of waste. All the heat produced is utilized as the plant is interconnected with the regional district heating system in Copenhagen. Ramboll has, […]
Data Optimising Waste and Biomass Plants
Computational Fluid Dynamics (CFD) – Value Creation of the Future The use of CFD in Combined Heat and Power Plants (CHP) means that you can have access to data on combustion processes, which otherwise would be impossible or very difficult to get as it either requires multiple stops in production or building an exact model […]
Wind energy – driving the global market
As the first country in the world, Denmark has decided to lead the transition and become entirely independent of fossil fuels by 2050. One element in reaching this target is to expand the share of renewable energy harnessed from wind, and this encompasses driving the development of an intelligent energy system capable of managing the intermittency of renewable energy.
Egaa Wastewater Treatment Plant is transformed to energy producer
Total energy renovation of the treatment plant at Egaa, just outside Aarhus, means that Aarhus Vand is setting new standards for developing treatment plants from energy guzzlers into energy producers. This has happened through entirely new technologies that exploit the green energy-production potentials in wastewater. The topping-out is a milestone in the technological development of […]
From wastewater to valuable fertiliser
At Aaby and Marselisborg Wastewater Treatment Plants Aarhus Vand extract phosphorus from the wastewater and sell it as valuable fertiliser under the name PhosphorCare. In 2013, Aarhus Vand opened the first full scale demonstration plant in Denmark at Aaby Wastewater Treatment Plant to test the viability of renewable phosphate production in Denmark. Today the plant […]
Converting Food Scraps into Biomass
Food waste and vegetable or fruit peelings are directly emptied into the BioMaster® and then converted into a homogeneous biomass. The need for additional water is minimal as the food already contains a high volume of natural liquid. The biomass is pumped by a specially designed pump through a closed system into a Biotank. The […]
Innovative Methods for Phosphorus Recycling
Enhanced demands for food production will increase the global demand for fertilisers such as phosphorus. The global sources of phosphorus are limited, and the increased demand will result in rising market prices and a global fight for control over the limited reserves emphasising the need for methods enabling phosphorus recycling. In such a market situation […]
Waste fuel recovery
PureDry is a revolutionary high-speed separator capable of recovering reusable fuel from waste fuel oil, a process that requires separate tanks for waste fuel oil and waste lube oil. It returns up to 2% of the consumed fuel volume to the fuel oil bunker tank, leaving only super-dry solids that can be landed as waste. […]
