Nowadays, traditional energy resources are going into a vulnerable condition gradually. On that note biogas is an emerging subsidiary solution. Generally, cow-dung is used as a basic raw material to produce biogas. In this study, various forms of putrescible waste like kitchen and vegetable waste were giving emphasis to produce biogas as a replacement of cow dung as well as good management of putrescible waste. 2000 kg of kitchen and 1050 kg of vegetable waste were used in a biogas plant continuously for 15 days with a waste/water ratio of 1:1.5. Average 133.33 kg of kitchen and 70 kg of vegetable waste generated 2.27 kg and 1.17 kg of biogas per day respectively. Moreover, the average time of burning of biogas for kitchen and vegetable waste was 7.92 h. and 4.08 h. per day in some respects. The benefit–cost ratio was greater than 1 for both cases that’s why it can be reckoned as an efficacious process. Autoregressive Integrated Moving Average (ARIMA) model was performed to forecast the amount of biogas generation for kitchen and vegetable waste for the next 10 years. The residual sum of square (RSS) value of the ARIMA model for kitchen and vegetable waste was 0.028437 and 0.139524 respectively which indicates accuracy. Finally, predictions of the amount of biogas generation are plotted with a 95% confidence interval. The forecast indicates that biogas from kitchen waste is more proficient than vegetable waste for the next 10 years. So, this putrescible waste can be a prominent raw material for next-gen biogas production.

基于ARIMA模型的餐厨垃圾沼气替代传统方法及未来预测

如今,传统能源正逐渐进入脆弱状态。就此而言,沼气是一种新兴的辅助解决方案。一般以牛粪作为生产沼气的基本原料。在这项研究中,各种形式的易腐垃圾,如厨房和蔬菜垃圾,都强调生产沼​​气作为牛粪的替代品,以及对易腐垃圾的良好管理。2000 公斤厨房垃圾和 1050 公斤蔬菜垃圾在沼气厂连续使用 15 天,废水比为 1:1.5。平均每天 133.33 公斤厨房垃圾和 70 公斤蔬菜垃圾分别产生 2.27 公斤和 1.17 公斤沼气。此外,厨余和蔬菜垃圾的沼气燃烧平均时间为7.92小时。和 4.08 小时。在某些方面每天。两种情况下的收益成本比都大于 1,这就是为什么它可以被视为一个有效的过程。使用自回归综合移动平均 (ARIMA) 模型来预测未来 10 年厨房和蔬菜垃圾的沼气生成量。厨房垃圾和蔬菜垃圾的 ARIMA 模型的残差平方和 (RSS) 值分别为 0.028437 和 0.139524,表明准确性。最后,以 95% 的置信区间绘制对沼气产生量的预测。预测表明,未来 10 年,厨余垃圾中的沼气将比蔬菜垃圾更有效。因此,这种易腐烂的废物可以成为下一代沼气生产的重要原材料。使用自回归综合移动平均 (ARIMA) 模型来预测未来 10 年厨房和蔬菜垃圾的沼气生成量。厨房垃圾和蔬菜垃圾的 ARIMA 模型的残差平方和 (RSS) 值分别为 0.028437 和 0.139524,表明准确性。最后,以 95% 的置信区间绘制对沼气产生量的预测。预测表明,未来 10 年,厨余垃圾中的沼气将比蔬菜垃圾更有效。因此,这种易腐烂的废物可以成为下一代沼气生产的重要原材料。使用自回归综合移动平均 (ARIMA) 模型来预测未来 10 年厨房和蔬菜垃圾的沼气生成量。厨房垃圾和蔬菜垃圾的 ARIMA 模型的残差平方和 (RSS) 值分别为 0.028437 和 0.139524,表明准确性。最后,以 95% 的置信区间绘制对沼气产生量的预测。预测表明,未来 10 年,厨余垃圾中的沼气将比蔬菜垃圾更有效。因此,这种易腐烂的废物可以成为下一代沼气生产的重要原材料。139524 分别表示精度。最后,以 95% 的置信区间绘制对沼气产生量的预测。预测表明,未来 10 年,厨房垃圾中的沼气将比蔬菜垃圾更有效。因此,这种易腐烂的废物可以成为下一代沼气生产的重要原材料。139524 分别表示精度。最后,以 95% 的置信区间绘制对沼气产生量的预测。预测表明,未来 10 年,厨余垃圾中的沼气将比蔬菜垃圾更有效。因此,这种易腐烂的废物可以成为下一代沼气生产的重要原材料。
