This document discusses the challenges and opportunities in optimizing biomass supply chains for bioenergy and biofuel production. It reviews the main routes for producing bioenergy from terrestrial and aquatic biomass feedstocks. Global biofuel production is growing due to benefits like increased energy security, lower emissions, and rural development. However, fossil fuels are finite and causing environmental damage, so alternatives are needed. The document examines optimizing supply chains from various biomass sources and the technologies used to produce ethanol, biodiesel, and other biofuels and their intermediates. Biochemical and thermochemical conversion processes are outlined.

Biomass-to- bioenergy and biofuel supply chain optimization:Ove rview, key issues and challenges presented by : Herson andres gonzalez
introduction  This paper describes the main challenges and opportunities in modeling and optimization of supply biomass bioenergy productions. It reviews the main routes of energy from biomass for bioenergy from terrestrial and aquatic products for biofuels.
introduction  Global biofuels production is growing steadily and will continue. Biofuels offer greater energy security, reduced greenhouse gas emissions and particulate matter, rural development, better vehicle performance and a reduction in oil demand.
Why? It is not a secret that fossil fuels (hydrocarbons) are finishing and we only hace resources for 20 years more, these are causing pollution, greenhouse damage to the ozone layer and therefore global warming; this is the reason why new alternatives are sought to meet these energy demands.
Cause  In this paper we study the ability of biomass to produce biofuels as these are more environmentally friendly, inexpensive and can be obtained from a variety of sources; that is the reason for studying several alternatives for the production of these.
How?  We look for to optimize supply chains of biomass for bioenergy, from aquatic and terrestrial biomass, moving from the laboratory to industrial plants behave like looking at these substrate concentrations to reproduce, high pressures and temperatures than operate among others.
Terrestrial raw materials  Many types of biomass are available, the first group includes grains of corn, sugar cane, soybeans, oilseeds, etc.. These raw materials are high in sugar or fat, and have a high yield after converted into bioethanol or biodiesel.
Terrestrial raw materials  the use of these raw materials for the production of biofuels could cause problems in terms of food prices and production.  The second group of materials are not edible starch, agricultural waste and forestry residues other crops
Aquatic raw materials  Aquatic Biomass includes a diverse group of photosynthetic algae and cyanobacteria ranging from (microalgae and cyanobacteria) to large seaweeds (macroalgae) Many macro algae, micro algae and cyanobacteria serve to drive the rapid growth of biomass. Certain strains make extremely efficient use of light and nutrients to grow.
Principal Products  Ethanol and other alcohols  Bio-diesel  Drop-in biofuels
Intermediates products  Sugars or carbohydrate derivatives  lipids  Syngas  Bio-oil
methodologies used  biochemical technologies The main biochemical conversion processes include pretreatment, hydrolysis, biological or chemical processing.  thermochemical technologies used in addition to high temperature catalysts to change the physical properties and chemical structures of biomass resources. There are two major pathways thermochemical reaction: gasification and pyrolysis.
Process Diagram
inference These are endless advantages and applications which have the production of biofuels, since they reduce the environmental impact considerably and also help meet the demand for oil in the world, as this is more cost-effective renewable and more environmentally friendly.
Thanks
