AVE’s Activity in 2016

The use of waste as alternative fuel and secondary raw material in Portugal.

AVE - Gestão Ambiental e Valorização Energética turnover amounted 10,865,213 euros in 2016. The figure reflects the 457,278 tons of waste managed by the company, of which 299,153 tons accounted for Alternative Fuels (AF).

Destruction of animal originated flours lost meaning in the turnover of the company, due to self-consumption of this waste in the animal byproducts processing plants. Thus, in 2016 8,310 tons of animal originated flours from the production of factories in Portugal and Spain were valorized with a ratio of 5% and 95% respectively.

The relationship with the tire industry, through its hiring with its managing entity, Valorpneu, allowed to continue establishing a relationship with the homologous entity of Spain and France and with operators of the Netherlands and England, thus allowing to import fragmented tires (Chips). The amount of tires and their fragments that were moved to the factories amounted to 48,390 tons in 2016, reducing by 16% compared to the year 2015.

AVE - Gestão Ambiental e Valorização, was also responsible for managing 194.000 tons in 2016 (218 thousand tons in 2015) of Refuse-derived Fuel (RDFs).

During the year 2016, experiences of pellet consumption were successfully carried out, which allows to consider this flow as strategic for the future.

Container imports have made it possible to increase the competitiveness and diversity of supply from new origins in the CDR flow.

The Industrial Hazardous Waste (IHW's) line that undergo a prior treatment at the blending facilities with preparation capacity provided for a total of 21.698 tons in 2016, reducing 4% in relation to 2015.

Market Position

The clarification of Alternative Fuels (AF) evaluation rules, based on a policy that provides a win-win relationship, has served as based for AVE – Gestão Ambiental e Valorização Energética’s proposals to be well received in the by enterprises, the economy and society as a whole in the country.

In 2015, AVE – Gestão Ambiental e Valorização Energética was part of an outstanding panel of speakers during the presentation of the Green Growth policies, sponsored by the Ministry of the Environment. In this context, it demonstrated the sustainability of co-processing.

As part of the participation in the SWP Waste Cluster - Smart Waste Portugal, in 2016, AVE – Gestão Ambiental e Valorização Energética is part of the work group regarding the disqualification of the CDR’s from waste to product. This work is an initiative proposed by urban waste operators, with a view to creating a potential market for the destination of the CDR’s.

The year 2016 was marked by the consolidation of a series of studies and projects that supported strategic initiatives in the market, which definitively marked the company's activity in the future, through the recognition of waste coprocessing and associated material valorization activity, which Clinker production supports.

The company continued to identify technical solutions to improve the quality of the CDR's on the market, particularly with regard to the reduction of moisture in urban solid waste.

In this regard, AVE – Gestão Ambiental e Valorização Energética optimized the exercise of laboratory analysis of the chemical and thermal components of AFs, having monitored about 1000 waste samples. This department is essential to support waste procurement and the essential quality control that will help ensure AF’s quality and stability alongside with economic evaluation.

In addition to the calorific parameters, chlorine and humidity, AVE – Gestão Ambiental e Valorização Energética, SA proceeded to implement two more analysis parameters, ash and grain size, essential for the process of assessing the quality / value of alternative fuels.

AVE – Gestão Ambiental e Valorização Energética, SA was incorporated in October 2003 with waste management purpose and its material or energy valorization for the cement industry using the co-processing method.

Co-processing

The co-processing consists of the complete destruction of waste - previously prepared and identified as suitable for replacing fossil fuel and / or raw materials in clinker production in cement kilns, ensuring product quality standards, energy efficiency and environmental protection in line with the official certification of these plants.

The use of waste as fuel and / or alternative raw material contributes to the preservation of limited and not renewable natural resources. Despite being part of an industrial process, co-processing of waste in cement kilns does not imply any excess - since there is no residual waste - or any environmental liabilities.

This technique widely used in various countries around the world since 1976 is scientifically proven as one of the best environmental and economic solutions as final destination of numerous waste streams, assuming as a preferred solution for the sustainable development of contemporary society.
