Environment industry

When they talk aboutenvironmental industry, many still imagine garbage trucks and sorting lines. This, of course, is part of the truth, but only the tip of the iceberg. In fact, this is a huge complex that begins with preventing pollution at the production stage. This is where the main paradox lies - often the most effective “ecological” ones. solutions are not born in ?green? startups, but at traditional, even “dirty” ones. industries, such as mining equipment. Because who, if not them, knows the entire cycle of impact on nature and has the resources to change it?

From iron and steel to an environmental resource

Let's take our work for example. I have been involved in the industrial equipment sector for many years, and I have seen how the demand is changing. Previously, the main parameter was “performance - cost”. Now it is increasingly heard: “What is the impact on the site and further processing?” This is the entry point intoenvironmental industryfor a machine manufacturer. We are no longer just a supplier of “hardware”, we are becoming a supplier of the technological cycle, where minimizing waste and energy consumption is a key characteristic of the product.

We had a project with one enrichment plant in the Urals. Old equipment resulted in huge losses of raw materials in “tailings”. - up to 15%. Plus, its operation required reagents, which are then difficult to dispose of. We proposed a complex based on separators. I won’t go into technical details, but the point is that we have reviewed the entire chain: from ore supply to concentrate storage. As a result, losses dropped to 4-5%, and the need for aggressive reagents disappeared almost completely. The savings for the client are millions, but what is more important is that the load on the tailings storage facility has been dramatically reduced. Here it is, a practical contribution: better recovery = less waste = less land acquisition area.

This is about the question of “green?” image. You can't just slap on an eco-label. The very essence of the process needs to be changed. And often this requires not revolution, but competent modernization. But there are pitfalls here too. Sometimes engineers, carried away by the efficiency of separation, forget about energy costs. It turns out there is less waste, but the carbon footprint from increased energy consumption negates the benefits. You have to constantly look for balance, and it's always a compromise.

LONGI: How production culture shapes an environmental approach

Here it is appropriate to recall the LONJI corporation (https://www.ljmagnet.ru). I am familiar with their work firsthand. When an enterprise with such a history - ?Shenyang Scientific Electromagnetic Co., Ltd. LONGJI? has been operating since 1993 - and on such a scale (140,000 m2 of space, more than 1,200 employees) it speaks about ecology, it sounds different. This is not marketing, but a matter of survival and responsibility. Producing 4,000 pieces of equipment per year, they simply cannot help but think about the life cycle of their products.

What did I learn from them? Systemic view. Their engineers are not designing just a magnetic separator. They model how it will behave in a specific technological chain of the customer, how it will affect the overall consumption of water and energy, and the wear and tear of associated equipment. This is integration intoenvironmental industry. Their website is not just a catalog; there are many technical notes specifically about increasing efficiency and reducing load. This is a valuable resource.

The personnel issue is also important. They have over 60% of their staff with higher education. This means that at the level of the designer or technologist there is already an understanding that his calculation or drawing will affect not only the operation of the crusher, but also the environmental balance of the entire quarry in 10 years. Such a production culture is the best basis for real, rather than declarative, environmental decisions.

Dips and dead ends: when is it “environmentally friendly?” doesn't mean ?practical?

Not everything was smooth sailing, of course. We had experience in introducing one “super-eco-friendly” one. closed water supply systems for flushing. The theory is ideal: zero discharge, saving water. In practice, the system turned out to be incredibly sensitive to the composition of the pulp, requiring constant monitoring and expensive reagents to maintain balance. The client, a coal mine in Kuzbass, returned to the old scheme with discharge into settling tanks after six months. Why? Because the complexity of maintenance and cost outweighed all savings.

This lesson was worth a lot. He showed that any solution must be adequate to the conditions and competencies of the personnel on site. Sometimes it is easier and more environmentally friendly in a global sense to modernize a settling tank than to introduce a high-tech complex that is not viable under the given conditions.Environment industryshould offer not ideal, but feasible options.

Another dead end is chasing trends without understanding the physics of the process. I remember there was a request for a “fully electric” one. enrichment scheme instead of “wet”. But for many types of ores, “wet” the scheme is not a whim, but a necessity. An attempt to replace it would lead to an increase in dust generation and energy consumption by several times. It took a long time to explain that environmental friendliness is a comprehensive indicator, and not just a rejection of one type of process.

The future: integration and digital

Now I see the main vector in integration. The equipment ceases to be an isolated unit. It becomes a node in the enterprise's digital network. Sensors on the LONGIE separator, for example, can transmit data in real time not only about productivity, but also about the quality of the concentrate, which allows you to flexibly change the operating modes of crushers or mills located earlier in the chain. This leads to preventive resource savings.

Digitalization is not about a beautiful interface. This is about collecting data for life cycle analysis. Knowing how equipment behaves under different conditions, we can design the next generation of machines with even lower energy consumption, longer service life, and taking into account the possibility of easy disposal. This is where the next breakthrough lies forenvironmental industry.

However, there is a risk here too - creating a “digital monster” that will require more resources for its work than it saves. The key, again, is in balance and in the applied, and not divorced from reality, use of technology. The engineer’s task is to remain a practitioner who sees behind the data a real quarry, real water and real kilowatt-hours.

Conclusion: ecology as an engineering discipline

So, back to the beginning.Environment industryFor me, this is primarily an engineering task. These are not slogans, but daily work to optimize processes, materials and energy flows. It is not done somewhere outside, but within traditional industries, by companies like LONGI, who set new standards through their products.

Success here is measured not by reports, but by specific figures: by how many percent losses have decreased, by how many cubic meters of water consumption has decreased, by how many years the service life of the unit has increased before replacement. These are boring, mundane metrics. But it is precisely from them that the real reduction in the burden on the environment comes into play.

Therefore, when people ask me what I do, I no longer just say “mining equipment”. I say - I am working to ensure that resource extraction and processing become part of a circular economy. Slowly, with mistakes, with compromises, but this is the only workable way forward. And it starts from the drawing board in the factory, not from a fancy presentation at a conference.
