Project summary

Project objectives: design and construction of the equipment for disposal of the wood-working industry waste in the form of chips and sawdust and of the nutrient yeast production waste in the form of technical hydrolytic lignin.

The accomplishment of the project goal is ensured by the following:

- existing modern equipment used in aircraft industry;
- highly skilled personnel;
- scientific and technical expertise of the authors and successful preliminary results;
- organization of production facilities close to consumers- the largest in Russia wood-working factories in Arkhangelsk region, processing of which wastes will take more than a decade;
- permanent and unsatisfied demand, existing on European markets, for the ecologically clean fuel produced on proposed industrial lines for utilization of carbon-containing wastes.

At Present in Russia and many other country branches of industry processing organic materials produce significant amount of wastes, presenting a serious problem for the ecology. Among such facilities are the wood-processing with chips and sawdust as a waste, nutrient yeast production with technical hydrolytic lignin as a waste, paper and pulp production, processing and utilization of organic wastes in agriculture, waste paper, urban garbage, etc. Millions of tons of the carbon-containing wastes have been collected on technological sites and areas of such plants during last 10-12 years. These wastes not only occupy large areas and make them useless for the economy, but also have bad effect on the ecology, spoil air, soil and underground water by chemically harmful agents, mutilate landscapes. For example, hydrolitic legnin contains up to 2% of sulphur and 5-7% of ashes. The disposal of the wastes-transportation, dumping, explotation of the ground, storage is dangerous for the ecology and needs large spendings. Thus, the present state of the practice and technology of the utilization and processing of organic wastes, in particular, in wood working industry, biotechnological (nutrient yeast production)' and other branches of industry, is clearly unsatisfactory from the point of view of economy and technology, it is characterized by high cost losses and harmful effect on the environment because of the large volume of non utilizable wastes.

At the same time there exists a real, guaranteed by the present state of the science and technology, possibility of a drastic improvement of efficiency of the mentioned facilities (wood-processing, pulp and paper production, nutrient yeast production, etc.) through a complex processing and utilization of carbon-containing wastes, obtaining from them useful ecologically clean products. Therefore, from being the object of spendings and ecological danger these wastes become a source of additional profit and income.

The present project is aimed at the design and building of a pilot line for the utilization of carbon-containing wastes, in particular - chips and sawdust in wood-working industries and technical hydrolytic lignin; the proposed technology after slight modifications can be extended to other kinds of organic wastes.

The project is developed on a basis of the scientific and technical experience, gained by the scientific-engineering firm PLL"Ecotech Ltd" (Moscow) and "Inventing firm "New Technologies" (Dubna, Moscow reg.), positive results of laboratory and experimental-demonstrative studies.

Qualification of the project authors is confirmed by a large number of monographs:

2. Complex utilization of raw materials and wastes, M. "Khimiya", 1989, pp.288.

6. Metallurgy and technology of coal, M., "Nedra", 1990, pp.328
7. Briquetting of ores, M., "Nedra", 1989, pp.183

As a result of many year studies, carried out by this organization, an original and efficient technology of the processing of the mentioned wastes has been developed.

Product of such a technology is ecologically safe shaped (pressed) briquets, objects of different sizes and shapes from cylinders with a diameter of 10-15 mm, to "bricks" and tiles without a filler, that presents a unique property in the briquetting technology.

As a result materials for two different purposes can be produced:

1. fuel:

a) for communal-general needs
b) fuel-regenerator, coke substitute, for metallurgy

2. building items-elements, details, decorating materials for non-critical objects, for example, cover plates, blocks for sidewalks, lattice for picket fences, etc.

These materials are especially efficient as a high-grade, sulfur-free low-ash fuel, having low cost and good consumers' properties (rigidity, moisture resistance, dust-freedom, etc.).

The fuel obtained from briquettes using carbonization can replace with a high economical and technological efficiency the coke and other expensive regenerators (charcoal, regenerating gases, hydrogen, some metals) in regenerating metallurgical processes, conversions, meltings. Among these processes: blast furnace melting, ferroalloy production, direct production of the steel from the iron-ore materials (enriched ore, concentrate, etc.) in smelting furnaces, as well as some other processes of the regeneration of metals and other materials from oxides through the use of solid regenerators in the general technology of the processing of mineral raw materials, wastes and intermediate products. Such a clean regenerator, better than coke, is highly valued on the international market.

The ecological cleanness of the produced material results from the absence of dangerous components, filler, i.e. chemically aggressive agents in it. All this in combination with the above mentioned performance and consumers' properties and advantages makes the products, fabricated from the wastes, safe for handling at the production stage as well as at home.
