Abstract: Testing of fuels comprising a domestic, commercial or bulky refuse fraction produced by multiple mechanical comminution, sorting and optionally drying operations, involves examination of individual fractions by using near infrared technology. Troublesome materials are removed, so that defined chlorine and Fl (not defined) or cadmium levels are attained at a defined heating value.  Independent claims are also included for:  (1) A fuel consisting of an undried domestic refuse fraction (50-100 mm) produced by multiple mechanical comminution and sorting operations, in which individual fractions are examined by means of near infrared (NIR) technology and troublesome materials are removed, so that at a heating value of 8000-13000 kJ/kg the chlorine content is 0.15-0.6% and the Fl (not defined) content is 20-100 mg/kg;  (2) A fuel consisting of an undried domestic refuse fraction (100-200 mm) produced by multiple mechanical comminution and sorting operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 12000-16000 kJ/kg the chlorine (Cl) content is 0.15-0.5% and the Fl (not defined) content is 40-100 mg/kg;  (3) A fuel consisting of an undried domestic refuse fraction (over 200 mm) produced by multiple mechanical comminution and sorting operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 13000-19000 kJ/kg the Cl content is 0.15-0.6% and the Fl content is 40-100 mg/kg;  (4) A fuel consisting of a classifier light fraction of undried domestic refuse fraction produced by multiple mechanical comminution and sorting operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 12000-16000 kJ/kg the Cl content is 0.3-0.9% and the Fl content is 20-100 mg/kg;  (5) A fuel consisting of undried domestic refuse produced by multiple mechanical comminution and sorting operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 8000-19000 kJ/kg the Cl content is 0.15-0.9% and the Fl content is 20-100 mg/kg;  (6) A fuel consisting of a dried domestic refuse fraction (50-100 mm) produced by multiple mechanical comminution, sorting and optionally drying operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 9500-15000 kJ/kg the Cl content is 0.2-0.8% and the Fl content is 25-115 mg/kg;  (7) A fuel consisting of a dried domestic refuse fraction (100-200 mm) produced by multiple mechanical comminution, sorting and optionally drying operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 13500-18000 kJ/kg the Cl content is 0.19-0.63% and the Fl content is 45-115 mg/kg;  (8) A fuel consisting of a dried domestic refuse fraction (over 200 mm) produced by multiple mechanical comminution, sorting and optionally drying operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 14500-22000 kJ/kg the Cl content is 0.19-0.75% and the Fl content is 45-115 mg/kg;  (9) A fuel consisting of a classifier light fraction of dried domestic refuse fraction produced by multiple mechanical comminution, sorting and optionally drying operations, in which individual fractions are examined by means of NIR technology and troublesome materials are removed, so that at a heating value of 13000-18000 kJ/kg the Cl content is 0.35-0.9% and the Fl content is 25-120 mg/kg;  (10) A fuel consisting of dried domestic refuse produced by multiple mechanical comminution, sorting and optionally drying operations, in which individual fractions are examined by means of NIR technology and troublesome materials are remove
