A minitube blanket for landfill gas collection and containment Moreover, due to numerous redundancies of corrugated polypropylene perforated pipes 10 inches (254 mm) apart, the minitube blanket offers a more reliable radius of influence to collect LFG than traditional LFG collectors 50-100 feet (15-30 m) apart. Furthermore, even though the traditional LFG collector had higher vacuum availability, the minitube blanket provided equal if not better flow rates. As presented in Figure 6, the average LFG flow rate for the traditional collector was 67 standard cubic feet per minute (2 standard m3/min), while the average LFG flow rate for the minitube blanket FIGURE 6 Comparative LFG flow rate Quantity Unit KG CO2 eq./lm Excavation Work Waste density 1.5 tons/m3 Trench height 0.5 meters Soil extraction for 1 lm 3 tons lm of trench per day 200 lm/day Tons of soil extracted per hour 85.7 tons Fuel consumption per hour 40 liters Fuel consumption for 1 lm 1.4 liters 30 dollars Soil extraction using machinery 4.12 Soil extraction/application Labor costs per hour Number of workers 2 Dollars for services for 1 lm 3.15 dollars 0.12 3.39 kgs 11.33 Distance to worksite 2000 kms one-way Transport of products 6.77 tons.kms Minitube blanket Name of product Weight per lm DRAINTUBE 500P LFG4 Transport to the site 1.74 Application of the product on-site using machinery lm applied in 1 hour 75 lm Fuel consumption per hour 20 liters Fuel consumption per lm 0.27 liters Labor costs per hour 30 dollars Number of workers 3 Dollars for services for 1 lm 1.2 0.79 Product application (labor) TABLE 1 Kg CO2 eq. emissions per linear meter for the minitube blanket 22 Geosynthetics | August September 2019 dollars 0.04 TOTAL 18.14
