for a sustainable eco-mobility with Sweden being the leading country using biogas

as vehicle fuel [14].

The wide range of biogas applications in the mobility and power sector creates a

basis for potential customers. Business leaders ideate biowaste as a nascent energy

source inasmuch orientating to biomethane is beneficial for the bioenergy industry

and may lead to a salubrious economy (Figure 31.1).

Aligned economic and environmental considerations may reinforce the waste

markets. Bolstering efforts to embrace waste treatment practices is conceivable;

however, contemplating efficient techniques to abate wastes is stimulus and

requisite to transit the economy into a sustainable path [16]. Broadly speaking,

mitigation of GHGs, secure supply of energy and commodities, and pursuit to ame-

liorate economies in rural areas are contaminant drivers to assure the leapfrogging

to a green gas economy.

The fickleness of the incumbent business and the uncertainty of the project prof-

itability hinder the boosting of renewable fuels (Figure 31.2). Censure on the biogas

market has been ascribed to the absence of a standardized framework. Albeit the

economic reforms are a pivotal impetus for the biogas industry economy, it may

efface the precariousness derived from biofuel projects [16]. However, the incessant

imminence of technological findings and improvements in the production of other

gaseous fuels might erode its competitiveness.

Anaerobic Biorefinery Approach

The wobbling price of biofuels, elevated power demand, and fossil fuel depletion

are subtle reasons for the transition into the biogas economy. Biogas has become a

point of contention for the biofuel industry that argues the mediocre AD efficiency is
