A concept designed to utilize the entire biomass feedstock , Renewable Raw Materials-RRM, producing bio-products that displace products originated from petroleum or high cost food feedstocks, extracting value in a series of staged industrial processes to optimize economics of production

The future biorefinery concept of science and industry is defined as a biorefinery that converts a variety of feedstocks, including residues, into a portfolio of products with improved energetic chain efficiency, improved economy and improved environmental effects, compared to standalone processes often producing only one or two products. This concept is also known as the third generation biorefineries.

• A typical example of a first generation biorefinery is a dry milling ethanol plant, which utilizes cereals as feedstock and a fixed production line consisting of ethanol, feed co-products and carbon dioxide • A phase two biorefinery is the wet milling technology which allows the production of various end-products depending on product demand using one feedstock (mainly grain) • To date, the third generation biorefineries have not yet been built, but are in research and development.

Based on Kamm et al., 2006; Kamm & Kamm, 2004b, four concepts of third generation biorefineries are in discussion and under development: 1. Lignocellulosic Feedstock (LCF) biorefinery 2. Whole-crop biorefinery 3. Green biorefinery 4. Two-platform concept

This model requires integration of processes and flows of inputs, optimization of industrial utilities and transportation logistics It also requires high yield conversion and large scale production for the purpose to reduce production costs, promote diversification and enable flexibility of production to respond to market demands, similar to the model used by the petrochemical industry . Biorefineries belong to the category of agribusiness and it should be considered as an extension of agricultural production chain and thus integrated physically in the process of planting, harvesting, processing and transformation of these plantations.

Why Biorefinery?
1. There is an increase in renewable resources (biomass)
2. Renewable resources becoming increasingly cheaper

some interesting Information……. - every year 27.712 Million tones of CO2 are emitted - The plastic-consumption utilizes about 6% of oil and 80% of this oil is used for transportation and heating - only 21% ( around 546,000 tons / year) of plastics produced in Brazil are recycled - Brazil produces 230,000 tons / day of solid waste - 22% of waste is plastic

• Current predictions indicate that by 2025, more than 30% of raw materials for the chemical industry will be produced from renewable sources …..
• Are you going to be part of it ?
•.....that will translate into cost savings , improvement of our enviroment and a creation of a new market......
