TIRE MANAGEMENT PROCES

Used tires are quite inert material, difficult to recycle, it is not biodegradable and contains substances harmful to environment and population, and therefore it requires recycling. Recycling of tires is transformation of used, useless tires into reusable materials or sources of energy. This process consists of following stages:

Collecting of tires to prevent disposal of tires into illegal waste landfills and nature. Although in Latvia also the management cost is included in the price of the tire, distributors of tires do not have a unified standard how to implement collecting and recycling of tires in real life, therefore this stage is not performed as efficiently as it should be.

Delivery of tires to recycling factories.

Cutting of tires into small pieces that significantly reduces the amount of waste and creates material that is easier to process. This action can be performed in two ways:

  • With mechanical systems;
  • With cryogenic systems by freezing the tire in very low temperature and then chopping into very small pieces.

Separation of the metallic mesh and further processing of the metallic parts.

Inspection and sorting of the parts of tires accordingly to the size of pieces.

Purification of the obtained rubber with the help of water and other cleansing agents.

Packaging and transporting of obtained material to the material manufacturing factories.

How to use recycled tires?

Tires can be recycled in several ways but mechanic recycling is the most common method also providing materials with the widest possible use. By mechanically recycling tires 3 materials can be obtained:

  • Rubber that can be reusable;
  • Metal that can be reusable;
  • Textile that can be used for power generation.

Obtained rubber can be used:

  • In construction as insulation material or filling;
  • Manufacturing of barriers and amortizing construction elements;
  • Manufacturing of explosive carpets (these carpets can be used also for covering of forest roads during the logging);
  • Drainage of landfills;
  • Provision of road insulation;
  • Manufacturing of traffic infrastructure objects;
  • Covering of playgrounds and sports tracks;
  • Manufacturing of soft flooring;
  • Generation of power to reduce consumption of non-renewable fuel;
  • Pyrolysis processes for power generation, further – manufacturing of lubricants;
  • Manufacturing of rubber chips and tire recycling textile;
  • To substitute rubber in manufacturing of new tires and other consumer products.

Regulations of the Cabinet of Ministers state that 80% of collected tires must be recycled in Latvia but there are no traceable data about the recycled amount, besides the capacity to recycle tires imported in Latvia is around 30%. The single form of state involvement into the solving of the tire waste problem is the imposed Natural Resources Tax that is EUR 660 per ton.

Industry data

Every year the amount of uncollected and untreated tires in Latvia continues to increase. In 2016, it reached already 47 767 tons and continuous to increase. In 2016, only 34% from the 15 003 tons of distributed tires were collected and recycled.

ANNUALLY 30% OF THE IMPORTED TIRES IN THE MARKET ARE NOT COLLECTED AND RECYCLED.

Responsible use of tires

  1. Purchase of tires. By purchasing premium quality tires, we can use them longer, preventing waste, besides responsible manufacturers care for the tire manufacturing process to comply with all environmental requirements and be as ecological as possible.
  2. Duration of use of tires. Tires should be changed every 5 to 6 years or when the tread depth is less than 4 mm. Tires should be changed even if they are seldom used. With time material of tires loses elasticity, becomes more rigid and thus does not provide sufficient traction with the surface of road. Safety of driving with tires of insufficient flexibility is identical to safety when driving with worn-out tires.
  3. Inspection of tires. Tires, including the spare tire, should be inspected regularly, at least once a month. Regular inspections are especially important if tires are used for a prolonged period of time. If you see that the rubber of tires is dry, rigid, has cracked, it means that rubber has lost its traits that are essential during the winter period. Winter tires are soft. If they are not soft and have such damages, it means tires are of poor quality and are not safe. You should not use them but purchase new winter tires.
  4. Seasonality of tires. Every year already since 1 October you can change summer tires for your vehicle to tires suitable for the winter season (both studded tires and standard tires). In autumn and at the start of winter, when Latvian weather turns colder and rainier, roads become slippery, therefore Road Traffic Safety Directorate (CSDD) recommends changing tires in due time to make the driving of car as safe as possible. Road traffic regulations state than from 1 December to 1 March all vehicles with the total mass not exceeding 3.5 t, should be mandatory equipped with winter tires. In spring experts recommend to change winter tires to summer tires, as summer tires provide fuel economy, better performance and, most importantly, safety on the road. From 1 May to 1 October it is prohibited to use studded tires.
  5. Types of winter tires. When considering efficiency of tires in various weather conditions, as well as suitability for driving onto different road coverings, winter tires are divided into the following categories: studded tires, ”European” tires and ”Scandinavian” tires.
    Studded tires are perfect for use on icy roads or on roads covered with dense layer of snow but on the dry asphalt or wet roadway it is best to use standard winter tires without studs.
    “European” type tires are developed for driving both on snow and asphalt. It should be noted that car equipped with “European” type tires provides sufficiently good performance also on the wet road cover.
    “Scandinavian” type tires will be utmost efficient on the slippery roads when parts of road are covered with snow.
  6. Utilization of tires. When tires are outdated, they must be delivered for recycling and it is prohibited to dispose of tires in inappropriate places. A fine up to EUR 1000 can be imposed for unwarranted disposal of tires. You can dispose of tires in special tire collecting points (each person can bring 4 tires), please find out addresses of these points in the website atkritumi.lv. Also any service station that changes tires will accept the old tires without extra charge.
