Wastewater and excreta an untapped resource for solving environmental risks

Published

on

A book by Stockholm Environment Institute (SEI) and the United Nations Environment Programme (UNEP), launched on World Water Day, reports that the sanitation waste of 50% of the global population is still disposed of without having been treated – posing enormous risks to both public health and the environment.

At the same time, this disposal means opportunities are being flushed away; instead, this waste could be used to provide more than 50 million tons of fertilizer nutrient, which would account for 25% of the current global demand.

“We need to reevaluate our view on wastewater and human excreta. Today’s approach to disposal means lost opportunities in the form of nutrients and organic matter which are being flushed away,” says Kim Andersson, Senior Expert at the Stockholm Environment Institute and one of the lead authors ofSanitation, Wastewater Management and Sustainability: From Waste Disposal to Resource Recovery. “Instead, we could use these materials to improve soils or produce clean burning, low carbon biogas. If cleaned properly, wastewater can even be turned into drinking water. Reusing this resource will generate new jobs and business models.”

The second edition of Sanitation, Wastewater Management and Sustainability: From Waste Disposal to Resource Recovery aims to bring about change by showing how improved sanitation and wastewater management can benefit both humans and the environment. The book looks beyond human health, marine environment protection and resource recovery to the many other ways that sustainable sanitation and wastewater systems can contribute to meeting the social, environmental and economic goals of the 2030 Agenda for Sustainable Development. It highlights job opportunities along the entire sanitation and wastewater value chain of the circular economy, as well as potential gains for education, economic productivity and gender equality. 

Important progress has been made in the last few years when it comes to increasing people’s access to basic sanitation. In 1990, around half of the global population did not have access to basic sanitation; by 2017, this number had been reduced to 26%. Current trends, including predicted population growth and the increasingly intensive consumption of natural resources, will continue to expand the need for improved excreta and wastewater management. At the same time, the challenges remain massive:  

  • About 2 billion people still lack basic sanitation. Out of this number, 670 million practice open defecation.
  • Nearly 700 million children do not have access to sanitation facilities in their schools.

“I hope the book will find its way to new audiences and inspire and provide guidance on how to work towards more sustainable sanitation and wastewater management. There is great potential for resource efficiency and recovery linked to sanitation waste streams. Most circular economy initiatives do not capitalize on this component today,” says Birguy Lamizana, Programme Management Officer in charge of wastewater at UNEP.

The book includes a section on the circular economy, since this is an area that has seen a boom in the adoption of policies and plans on regional, national and city levels. One example is the EU, which has launched a series of policies and action plans on the circular economy during the last 5 years.

In addition to the emerging circular economy approach, recent years have seen a stronger focus on business models linked to sanitation and wastewater management, especially from a resource recovery perspective. The book highlights some of the lessons learnt in this area.

Sanitation, Wastewater Management and Sustainability: From Waste Disposal to Resource Recovery is a joint effort, across a global network of researchers and practitioners, to collect successful approaches and experiences which represent diverse geographic and socioeconomic contexts, as well as multiple challenges and potential solutions. The book will be available in English and Spanish and provides guidance on how to work towards more sustainable sanitation and wastewater management.

Norwegian scientists finally find good news from Norilsk Nickel

Published

on

The state of the environment in the border areas is the main topic of the «Pasvikseminaret 2021», organized by the public administrator in Troms county and Finnmark in cooperation with the municipality of Sør-Varanger municipality.

The purpose of the annual Pasvik seminar is to provide the local population and local politicians all information about the environmental situation in the border area Norway – Russia. Program focused on pollution from the Nickel Plant and monitoring of the environment in the border area.

The activities of Norilsk Nickel have been the main focus of the workshop for many years.

For the first time in many years, Norwegian scientists have found only positive news from Russia.

Tore Flatlandsmo Berglen, a researcher at the Norwegian Institute for Atmospheric Research (NILU), noted a significant improvement in air quality in the border area. Berglen remembered the 70-80s of the last century, when one of the divisions of Norilsk Nickel “Pechenganikel” annually emitted 400 thousand tons of sulfur dioxide into the atmosphere, in the 90s this figure dropped to 100 thousand tons. After the closure plant in Nikel in December 2020, the content of sulfur dioxide and heavy metals in the atmosphere at the border between Norway and the Murmansk region meets all international requirements.

“And I know that these emissions from the Kola MMC will continue to decline. Compared to 2015, this figure will be 85 percent. This is very positive news. Air quality issues are being addressed in the right direction. We have been talking about this for many years and finally the problem has been resolved, emissions significantly reduced. This is the most excellent presentation I have ever make! ” – said Tore Berglen.

Earlier it was reported that Russia’s Norilsk Nickel, the world’s largest producer of nickel and palladium, closed its smelter in the city of Nickel in northern Russia at the end of 2020. Kola is a subsidiary of Norilsk Nickel on the Kola Peninsula with mines, processing plants and pellets in Zapolyarny, as well as metallurgical plants in Monchegorsk and a plant in Nikel, which closed at the end of December 2020.

The Norwegian environmentalists who participated in the workshop also noticed positive changes.

“The smelter is closed and Norilsk Nickel is working hard to become a ‘green’ metallurgical company – it reduces emissions, uses advanced technology and cooperates with Pasvik nature reserve which is our good partner in Russia. Today, a lot of interesting things are happening in the border areas. We have many common interests and there is a certain key to ensuring that everything works out for us – this is good coordination, cooperation, a large knowledge base,” said the representative of the environmental center NIBIO Svanhovd.

Other studies examining water resources, fish, berries, also prove that nature in the border area is recovering. All this testifies to the work of ecologists who care about the environment.

“We see examples of what has already been done. And this allows us to plan with confidence our future joint work, projects,” says senior adviser representative Anne Fløgstad Smeland at the county governor in Finnmark.

New project to help 30 developing countries tackle marine litter scourge

Published

on

A UN-backed initiative aims to turn the tide on marine litter, in line with the global development goal on conserving and sustainably using the oceans, seas and marine resources. 

The GloLitter Partnerships Project will support  30 developing countries in preventing and reducing marine litter from the maritime transport and fisheries sectors, which includes plastic litter such as lost or discarded fishing gear. 

The project was launched on Thursday by the Food and Agriculture Organization (FAO) and the International Maritime Organization (IMO), with initial funding from Norway. 

Protecting oceans and livelihoods 

“Plastic litter has a devastating impact on marine life and human health”, said Manuel Barange, FAO’s Director of Fisheries and Aquaculture.  “This initiative is an important step in tackling the issue and will help protect the ocean ecosystem as well as the livelihoods of those who depend on it.” 

Protecting the marine environment is the objective of Sustainable Development Goal 14, part of the 2030 Agenda to create a more just and equitable future for all people and the planet. 

The GloLitter project will help countries apply best practices for the prevention and reduction of marine plastic litter, in an effort to safeguard the world’s coastal and marine resources. 

Actions will include encouraging fishing gear to be marked so that it can be traced if lost or discarded at sea. Another focus will be on the availability and adequacy of port reception facilities and their connection to national waste management systems.  

“Marine litter is a scourge on the oceans and on the planet”, said Jose Matheickal, Head of the IMO’s Department for Partnerships and Projects. “I am delighted that we have more than 30 countries committed to this initiative and working with IMO and FAO to address this issue.” 

Five regions represented 

The nations taking part in the GloLitter project are in Asia, Africa, the Caribbean, Latin America and the Pacific. 

They will also receive technical assistance and training, as well as guidance documents and other tools to help enforce existing regulations. 

The project will promote compliance with relevant international instruments, including the Voluntary Guidelines for the Marking of Fishing Gear, and the International Convention for the Prevention of Pollution from Ships (MARPOL), which contains regulations against discharging plastics into the sea.

Paris goals still ‘long way off’

Published

on

The world is “a long way off” from meeting the goals of the landmark Paris Agreement on Climate Change, the President of the crucial upcoming UN climate conference, COP26, said on Thursday.

British politician Alok Sharma was speaking during a global discussion on the ‘green’ transition in sectors such as energy, transport and food systems, held as part of the 2021 Spring Meetings of the World Bank and the International Monetary Fund (IMF). 

“Oceans are warming, storms are intensifying, and yet we are a long way off meeting the goals of the Paris Agreement”, he told the virtual meeting.  “Unless we act now, the human, economic and environmental cost will dwarf anything that humanity has seen before.”  

John Kerry: Last chance to get serious 

COP26, which will be held this November in Glasgow, Scotland, aims to accelerate action towards the Paris treaty goals, which centre around limiting global temperature rise to 1.5 degrees above pre-industrial levels by curbing greenhouse gas emissions.   

John Kerry, US Special Presidential Envoy for Climate, called the conference “the last best opportunity we have to get real and serious.” He particularly urged developed countries to step up efforts to reduce emissions. 

“It is essential we raise ambition; we make Glasgow the next step in defining not what we’re willing to do but what we really need to do in order to be able to get the job done.” 

Prince William: Invest in nature 

For Prince William, the Duke of Cambridge, COP26 represents an opportunity to put nature at the heart of the climate fight.  He called for banks to invest in nature, noting that spending so far has been minimal.  

“We cannot recover sustainably from coronavirus, eradicate global poverty, achieve net-zero emissions, or adapt to climate change, without investing in nature”, he said. 

UN envoy on energy for all 

Energy access must also be part of the green transition, according to Damilola Ogunbiyi, Chief Executive Officer at Sustainable Energy for All (SEforALL), a UN partner.   

Globally, nearly 800 million people do not have access to electricity, while 2.8 billion lack access to clean cooking sources, she said, which is equivalent to the populations of Africa, Europe and China combined. 

To change their lives, she recommended that governments focus on policies in the areas of promoting renewable and sustainable energy, and on ease of doing business and regulations. Again, financing here is needed, together with commitment. 

“We all see that globally, when we come together, just the amazing work we can do, and the COVID vaccine is a perfect example”, said Ms. Ogunbiyi, who is also the Special Representative of the UN Secretary-General for Sustainable Energy for All. 

“We literally have to have a COVID vaccine response to help a lot of developing countries because it’s not that they don’t want to transition, or they don’t want to do the right thing. It’s a fact that if you do need to transition, there is a lot of funding that is needed.
