Scrap Tyre Management Pathways and Their Use as a Fuel—A Review

2016

Abstract:This article provides a review of different methods for managing waste tyres. Around 1.5 billion scrap tyres make their way into the environmental cycle each year, so there is an extreme demand to manage and mitigate the environmental impact which occurs from landfilling and burning. Numerous approaches are targeted to recycle and reuse the tyre rubber in various applications. Among them, one of the most important methods for sustainable environmental stewardship is converting tyre rubber components into bio-oil. In this study, scrap tyre management techniques including landfill, retreading, recycling, combustion, and conversion to liquid fuels was reviewed (including gasification, hydrothermal liquefaction, and pyrolysis). The effects of parameters such as reactor types, pyrolysis temperature, and catalyst on the oil, gas and solid products in pyrolysis process were investigated.

“…The average caloric value reported for ST processed by pyrolysis is 33 MJ/kg [75], equivalent to 9.17 kWh/kg, but energetic values of 38, 37 y 28 MJ/kg, have been respectively reported [29,50,76]. Assuming that a single scrap tire has a mean weight of 10 kg, then it can be inferred that each year Puerto Rico generates 50 × 10 6 kg ST (~137,000 kg/day).…”

“…Being pyrolysis the most recommended procedure for processing scrap tire [38][39][40][41]44], new models deserve to be developed to characterize its kinetics and to interpret the techniques that will result in obtaining a gas or liquid by-product with high calorific value [54], and to validate that energy recovered exceeds the one required to initiate and sustain the process [53]. Certainly pyrolysis presents marketing reticence due to the high costs of installation of the facilities [29,76], but this factor can be addressed through collaboration networks [70], and the fact that initial costs are recovered in the short-term [29].…”

Puerto Rico generates and disposes nearly five million/year scrap tires (ST), of which 4.2% is recycled and 80% is exported. The Island has one of the world highest electrical service tariff ($0.28 kWh), because of its dependency on fossil fuels for power generation. The Government has not considered ST for electricity production, despite more than 13,000 ST are generated daily, and paradoxically exported for that purpose. Theoretically, if ST recycling increases to 10% and assuming that the caloric value of ST be 33 MJ/kg, it was estimated that scrap tires processed with pyrolysis can supply annually about 379 MWh, a potential value that shall not be unnoticed. This paper is a literature review to describe the legal, technical, and economic framework for the viability of ST for power generation in Puerto Rico using pyrolysis, the most recommended process for ST energy recovery. Data of ST from Puerto Rico was used to model the potential of ST for pyrolytic energy conversion. The herein article is intended to invite other insular countries and territories, to join efforts with the academic and scientific community, and with the energy generation sector, to validate ST as a sustainable option for energy generation.

Production of Synthetic Natural Gas from Refuse-Derived Fuel Gasification for Use in a Polygeneration District Heating and Cooling System

2016

Nowadays conventional district heating and cooling (DHC) systems face the challenge of reducing fossil fuel dependency while maintaining profitability. To address these issues, this study examines the possibility of retrofitting DHC systems with refuse-derived fuel (RDF) gasifiers and gas upgrading equipment. A novel system is proposed based on the modification of an existing DHC system. Thermodynamic and economic models were established to allow for a parametric analysis of key parameters. The study revealed that such an upgrade is both feasible and economically viable. In the basic scenario, the retrofitted DHC system can simultaneously produce 60.3 GWh/year of heat, 65.1 GWh/year of cold, 33.2 GWh/year of electricity and 789.5 tons/year of synthetic natural gas. A significant part of the heat load can be generated from the waste heat of the upgrading equipment. The investment in retrofitting the polygeneration DHC system presents a payback period of 3 years.
