Table 4.

Assumptions for economic analysis based on the case study.

7	Gas value based on methane content (IRENA, reference)	$0.22–$0.39/m3
8	CAPEX (please refer to supplementary tables for a breakdown of the equipment, CAPEX based on a quotation from a Chinese manufacturer)	$6448
9	OPEX Annual (5% of CAPEX to cover maintenance, electric consumption and consumables). (Assumption provided by equipment manufacturer)	$322.4
10	Investment in Working Capital. Calculation: 3 years × [9]	$967.2
11	Total investment. Calculation: [8] + [10]	$7415.2
12	Project lifetime (provided by equipment manufacturer)	10 years
13	Discount rate/cost of capital (given)	8%
14	Tax—the project is tax-exempt (given)	0%
15	Depreciation is not accounted for since the project in the case study is tax-exempt. Depreciation will only have an impact on cash flow as a tax shield	Not accounted for
