The world´s non-renewable natural resources are being consumed at an unsustainable rate. At the same time, pollution from industry and transportation is approaching levels unbearable for nature and mankind.
Industries can respond to this through many means, including innovations and the development of new clean technologies.

The use of non-renewable natural resources is unavoidable in modern society. However, the amount and manner in which these resources are used make a huge difference. Furthermore, preventing waste at all stages is essential.
Mankind is currently consuming natural resources at a rate 1.5 times faster than our earth can sustain. In a business-as-usual scenario, by 2030 we will consume resources to the equivalent of 2 earths and by 2050 nearly 3 earths.
Modern societies are based on the exploitation of many natural resources, including metals and minerals. Mining activities can cause a significant impact on the environment if appropriate technologies are not used and sound principles not followed.

For Metso, material efficiency has two dimensions: Its own internal manufacturing processes and the technologies, products and services it offers to its customers.
Metso's solutions are particularly related to the energy and raw materials efficiency of our customers’ production processes, the use of renewable energy sources, recycling, the efficient use of water, the reduction of emissions and process optimization.
and components account for about 50% of Metso's total operational costs
Compañía Minera Antamina is a polymetallic mining company in the central Peruvian Andes, some 4,300 meters above sea level. It represents one of the main locations of the Peruvian mining industry.
In collaboration with Metso, Antamina mine has consistently minimized its energy consumption by up to a quarter while exceeding its production targets. This has been achieved by using Metso´s process know-how without significant investments and by integrating and optimizing the structure of the mining process operations.

Fresh water is vital to life and yet it is a scarce resource. Although critical to nature and human communities, the availability of clean fresh water is threatened by numerous factors, including excessive consumption by industry, agriculture and households as well as by pollution through harmful effluents.
Some industrial processes consume so much water that they need to limit competing for scarce water resources with the surrounding habitat, agriculture or local community. New technologies can often help to recycle water and cut effluents far better than before.
Ultimately, saving water can be an attractive business case for industries such as, pulp, paper, mining and energy. Another serious challenge is the treatment of communal wastewater, which boils down to the question of quantity and quality of discharged treated water. Modern embedded measuring and control systems can make a big difference.
Only 3% of all the planet's water is fresh
Of all used freshwater, industries currently use 23%
The mining industry typically uses huge amounts of water for enriching mineral ores. However, by applying modern industrial monitoring, control and automation technology, it is possible to reduce water consumption considerably. This is done through increasing water recycling and improving the efficiency of dewatering equipment.
Instead of controlling individual parts of the process separately, it is now possible to integrate comprehensive water management solutions including process optimization and automatic control systems. These technologies are available not only for the mining industries, but also for the pulp, paper, chemical and other industries.
Metso's Goal 2020 reduce consumption by 15% compared to 2012
Ravensview Water Pollution Control Plant is located along the St. Lawrence River in Canada. In conjunction with a facility upgrade and capacity increase to 95,000 m3/d in 2011, a Metso TS system was installed.
Metso Total Solids Transmitter is based on continuous microwave measurement of solids. It optimizes the existing wastewater process capacity by more efficient follow up of mass balance with reliable measurements. As a result, the pumps are used only when necessary. In addition to reducing water discharge, the risk of digester flooding is reduced and the need for maintenance is minimized.
Volume flow and heating costs down by approximately 10%
Approximately 8% increase in annual gas production
Climate change threatens biodiversity and people’s livelihoods globally. To address this crisis, there is an urgent need to reduce carbon dioxide emissions. At the same time, we have to prepare for the consequences of global warming, which is already taking place.
Greenhouse gases like carbon dioxide exist naturally, but mankind has pushed their level well beyond bearable boundaries. The main causes are emissions from burning fossil fuels for energy (coal, oil, and natural gas) and from transportation. The latter alone is responsible for a quarter of the global carbon dioxide emissions. At the same time, clearing of forests is reducing their own natural counterbalancing ability.
Two years in preparation, WWF's Energy Report presents a challenging scenario, set in 2050, of a world run entirely on renewable energy. This is possible if human ingenuity is focused on the issue on a broad scale.
2013 397 ppm CO2 (parts per million)
2005 378 ppm CO2 (parts per million)
Metso works for sustainability and the abatement of global climate change on two fronts: by providing customers with technological solutions and by working internally to reduce its own ecological footprint.
When used by customers in the natural resources industries, Metso's energy and raw material saving technologies provide a benchmark and evidence of proven solutions. At the same time, Metso sets internal targets and invests in measures to do its best for our environment.

Vaskiluodon Voima's plant in Vaasa, Finland is the biggest biomass gasification plant in the world. The fuel of this plant consists of wood residues of various quality and different humidity levels which traditionally creates challenges for the operation and maintenance.
The Metso DNA automation system with advanced measurement, control and management features secures the optimal burning conditions, high energy yield and a reduced need for maintenance.
Urbanization entails the expansion of densely populated areas; at the same time, industries serving commerce and employment in urban areas have to adapt in many ways. WWF engages with major companies and their supply chains to change the way commodities are produced, processed, transported and consumed.
Manufacturing is always linked to the use of natural resources. Therefore the recognized need to reduce, reuse and recycle resources has become a driver for businesses providing innovations and commercial solutions.
From the sustainability point of view, the life cycle of goods matters. It is a question of not only manufacturing, but the entire process -- from sourcing to manufacturing and the final disposal or reuse of the goods at the end of their lifetime.
The growing concern over the availability of the earth’s resources is already having a strong impact on Metso's customer industries.
Eco-efficient technologies play an important part in adapting to this challenge. For Metso, a key part of its business is to offer solutions that help customers. Not only to save energy and raw material costs, but also to fulfill the environmental requirements they have set for themselves or which are imposed on them by regulatory measures.
The giant aggregate producer Norsk Stein, a subsidiary of Mibau, has operated Scandinavia’s largest quarry in Jelsa, Norway, since 1987.
In 2011, Metso supplied the company with new and optimally designed crushing chambers. In addition to its higher capacity, the chambers have a significant positive effect on Norsk Stein's energy consumption and costs. Metso and Norsk Stein continue their close cooperation to significantly extend the wear life of the chamber.
