BIOVALSA将开发一种新的工艺，能利用农业废料制造生 物塑料，成为石油基合成替材料的可持续代品。该项目旨在研 发从稻草中回收生物价值的可替代方式，从而避免高昂的酶制 剂成本。具体而言，其思路是用其它处理方法取代常规方法（ 酶制剂），用来回收木质纤维素生物质（lignocellulosic bio- mass）中纤维素（cellulose），半纤维素（hemicellulose ） 和木质素（lignin）这三种成分，用于生物塑料工业中所感兴 趣的各种应用。 纤维素可用来生产乳酸（lactic acid），乳酸是生产聚乳酸 （PLA）的关键化合物，而聚乳酸又是应用最为广泛的生物塑 料；半纤维素可用来生成琥珀酸（succinic acid），琥珀酸是 生产另一种可持续生物聚合物聚丁二酸丁二醇酯（PBS）的必 要材料，PBS具有较优的柔韧性和耐热性；木质素的抗菌特性 使其被回收用作添加剂来防止微生物繁殖，这进一步提高了这 些可降解可堆肥废料的市场价值，并拓展了其潜在应用。 合作公司和研究中心 BIOVALSA项目由AIMPLAS塑料技术中心协调，分享其在 废物回收和有机聚合物合成方面的宝贵经验，并联手瓦伦西亚 理工大学（Polytechnic University of Valencia）食品工程学院 （FoodUPV）的专家们和其它三家位于瓦伦西亚自治区的企 业。Bioban公司将贡献其基因组分析能力，确定最适合处理 废料的细菌菌株；Viromii公司将研究拓展用于生物复合材料新 工艺的经济可行性；Prime Biopolymers公司作为终端客户， 将负责生产生物材料，并分析项目期间产出材料的适用性。 该项目正在其发展的第一年，在采用不涉及有毒物质的替 代方法分离稻草成分方面已取得进展。同时也正在测试能够分 解纤维素和半纤维素并生成乳酸和琥珀酸的不同细菌和微生物 菌株，用来生产生物塑料的必要材料。 BIOVALSA项目符合由IVACE+i Innovation推动的战略专 业创新委员会（CEIE）关于循环经济和技术赋能战略。在循 环经济方面，它符合通过研发材料和技术，利用废料生产高附 加值产品的战略。在技术赋能方面，它倡导应用生物技术来改 善工艺和产品。该项目也契合瓦伦西亚自治区只能专业化战略 （S3）的主旋律，该战略由该地区工业、旅游、创新和贸易 部共同协调。 B IOVALSA will develop a new process that will enable the use of agricultural waste to manufacture bioplas- tics, a sustainable alternative to petroleum-based synthetics. This initiative aims to develop alternative routes for recovering value from rice straw biomass, thereby avoiding the use of costly chemical compounds. Specifi- cally, the idea is to replace the usual treatments with others that allow the three fractions (cellulose, hemicellulose and lignin) that make up the lignocellulosic biomass to be re- covered for use in various applications of interest to the bioplastics industry. Cellulose will thus be used to produce lactic acid, a key compound in the manufacture of PLA, the most widely used bioplastic, while hemicellulose is expected to yield succinic acid, which is necessary for the production of PBS, another sustainable biopolymer with greater flexibility and heat resistance. Finally, the antimicrobial properties of lignin make it suit- able for recovery and use as an additive to prevent the pro- liferation of microorganisms, which increases the market value and expands the potential applications of these bio- degradable and compostable materials. Collaborating companies and centres Coordinated by AIMPLAS, which contributes its experi- ence in both waste recovery and biopolymer manufactu- ring, “BIOVALSA” also brings together specialists from the University Institute of Food Engineering at the Polytechnic University of Valencia (FoodUPV) and three other compa- nies based in the Valencian Community. Bioban will con- tribute its genomic analysis capabilities to identify the most suitable bacterial strains for carrying out the treatments, while Viromii will study the economic viability of new pro- cesses for obtaining biocomposites. Finally, Prime Biopo- lymers, as the end customer, will be responsible for producing the biomaterials and analyzing applicability of the materials obtained during the project. The project is in its first year of development, during which progress has been made in separating the compo- nents of rice straw using alternative methods that do not involve toxic substances. Different strains of bacteria and microorganisms capable of breaking down cellulose and hemicellulose to generate the lactic and succinic acids ne- cessary for the production of bioplastics are also being tested. BIOVALSA is aligned with the conclusions of the Strategic Specialised Innovation Committees (CEIE) on Circular Eco- nomy and Enabling Technologies, promoted by IVACE+i In- novación. In the first case, it responds to the development of materials and technologies for the production of high added-value products from waste and, in the second, it urges the application of biotechnology to improve proces- ses and products. It also falls within the main axes of the Valencian Community's Smart Specialisation Strategy, S3, which is coordinated by the Regional Ministry of Industry, Tourism, Innovation and Trade.
