Mục đích của nghiên cứu là khảo sát đơn yếu tố tỉ lệ phối trộn thích hợp giữa enzyme (E) và chế phẩm vi sinh vật có ích (EM), tỉ lệ nước bổ sung, nhiệt độ ủ, thời gian thủy phân ảnh hưởng tới quá trình thủy phân khô đậu tương bằng chế phẩm enzyme alcalase. Hàm lượng protein hòa tan trong dịch thủy phân được xác định bằng phương pháp Lowry. Kết quả khảo sát tương ứng là: EM 2% + E 1.5%; 4 (ml/g); 45ºC; 8 h. Trên cơ sở khảo sát các yếu tố ảnh hưởng đến điều kiện thủy phân, chúng tôi nhận thấy tỷ lệ phối trộn giữa enzyme và EM, tỷ lệ nước bổ sung, nhiệt độ ủ, thời gian thủy phân là những yếu tố ảnh hưởng mạnh đến quá trình thủy phân. Bằng phương pháp quy hoạch thực nghiệm Box- Behnken đã tìm được điều kiện tối ưu quá trình thủy phân khô đậu tương là tỷ lệ phối trộn giữa enzyme và EM là EM 2% + E 1.5%, tỉ lệ nước bổ sung là: khô đậu tương: 4.2, nhiệt độ ủ 45ºC, thời gian thủy phân 8.53 giờ. Kết quả thực nghiệm cho kết quả có độ tương thích cao với mô hình.

Detoxification Process

Ethanol fermented from potato peels is proposed as one alternative source of renewable energy called bioethanol. In this research bioethanol was produced through four stages namely acid hydrolysis, detoxification, fermentation and distillation. The acid hydrolysis process was carried out using sulphuric acid at 100oC for 60 minutes. The detoxification process was carried out by adding NH4OH into the hydrolyzate prior to fermentation. Distillation was performed up to 100oC and the distillate with the BP of 78-84oC was determined for its ethanol content using gas chromatography. The ethanol produced from 5 grams of dried potato peels through fermentation for 4, 5, 6, and 7 days 3.54%; 4,85%; 5,35%; and 6.15% respectively.

Suitable Process

Recently, textiles and their end-of-life management have become the focus of public and political attention. In the European Union the revised waste framework directive defines textiles as municipal waste and stipulates their separate collection by 2025. In the context of these developments, this paper summarises briefly the current state-of-the-art in textile recycling. It is evident that recycling methods are not yet fully developed. This is especially the case with multi-material textiles, which are composed of two or more polymers that are incompatible for recycling. In the practical part of the communication, results are presented which show that enzymatic hydrolysis is a suitable process for recycling textiles made of cotton and polyester. After a complete removal of cotton, the remaining pure polyester fibres undergo a re-granulation and post-condensation step. The so obtained recycled polyester is fed back into the textile processing chain and finally towels are obtained. The main steering parameters of the enzymatic hydrolysis process are described. The study proves that solutions in accordance with the Circular Economy in the textile sector are available but an industrial implementation has not yet been realised.

In this study, the montmorillonite (MMT) clay was modified with NH4Cl, and then the structures were exfoliated or intercalated in a polylactic acid (PLA) matrix by a torque rheometer in the ratio of 0.5, 3.0, 5.0 and 8.0 wt%. X-ray diffraction (XRD) revealed that the organic modified-MMT(OMMT) was distributed successfully in the PLA matrix. After thermal pressing, the thermal stability of the mixed composites was measured by a TGA. The mixed composites were also blended with OMMT by a co-rotating twin screw extruder palletizing system, and then injected for the ASTM-D638 standard specimen by an injection machine for measuring the material strength by MTS. The experimental results showed that the mixture of organophilic clay and PLA would enhance the thermal stability. In the PLA mixed with 3 wt% OMMT nanocomposite, the TGA maximum decomposition temperature (Tmax) rose from 336.84 °C to 339.08 °C. In the PLA mixed with 5 wt% OMMT nanocomposite, the loss of temperature rose from 325.14 °C to 326.48 °C. In addition, the elongation rate increased from 4.46% to 10.19% with the maximum loading of 58 MPa. After the vibrating hydrolysis process, the PLA/OMMT nanocomposite was degraded through the measurement of differential scanning calorimetry (DSC) and its Tg, Tc, and Tm1 declined.
